I need an experienced Windows specialist to jump in remotely and keep my small network running smoothly. The environment spans Windows Server 2016, Windows Server 2019 and a handful of Windows 10 workstations. Typical assignments range from one-off fixes to short configuration sprints, so I’m looking for someone who can respond quickly, diagnose accurately and document any changes made. Scope of work Over the coming weeks I expect help with: • Service configuration – DNS, Active Directory, and File & Print Services • Issue troubleshooting – anything from failed roles or features to odd workstation errors • Performance and security checks – tightening policies, reviewing event logs, tuning resources You will connect via remote session (VP...

Heavy bursts of visitors are knocking my landing page offline. Each spike fills the nginx error log with 2026/02/09 20:32:47 [error] 949181#949181: *409046 connect() to unix:/var/run/php/ failed (11: Resource temporarily unavailable) while connecting to upstream, client: , server: , request: "GET /pW321xkxUy/?zoneid=9843359 HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/:", host: "" I’ve confirmed the trigger is a high number of simultaneous users, not bots or unusual request types. What I need—urgently—is a Linux-savvy engineer who can stabilise the stack so the site stays up no matter how fast traffic arrives. Stability and uptime are my top priorities; raw speed tweaks are welcome only if they don’t compromise resilience. You...

My PHP 8.x application has picked up a fair amount of dead weight—unused files, legacy snippets, and the odd warning that only shows up in the logs. I need a developer who can open the hood, keep what truly matters, and scrap the rest while making sure everything that stays runs flawlessly. Here’s what I’m asking you to do: • Read the entire codebase, identify the core file(s), and strip away anything that isn’t required. • Hunt down every notice, warning, or fatal error and resolve it so the script executes cleanly on PHP 8.x with error reporting turned up. • Where you see obvious performance wins—query consolidation, tighter loops, lighter includes—go ahead and tune them. • I’m not entirely sure which smaller features ...

My custom e-commerce site is built on Laravel, not on Shopify or WooCommerce, and I need a sharp developer to tidy up a few pain points. First, a handful of pages are throwing 404s or directing to the wrong place. I’d like those links traced, corrected, and any underlying routing issues cleaned up so future content changes don’t break again. Second, page loads feel sluggish. I’ve spotted heavy database queries, un-optimised images, and a couple of third-party integrations that look chatty. I’d like you to profile these bottlenecks, refactor the queries, compress or lazy-load media where it makes sense, and audit the external calls so they only fire when truly needed. Deliverables • All broken links/pages resolved and verified • Average page load tim...

My team and I have a logistics-focused FlexSim model that is about halfway complete, but the process flow stalls the moment entities reach the very first node. The start node keeps throwing “process call function” errors, so the rest of the flow never activates. I need someone who knows Process Flow inside out to: • inspect the current model (including the embedded FlexScript we have already written) • pinpoint why the start-node call is failing • apply the correct fix so tokens move forward and downstream logic resumes without side effects Once the error is removed, please run a short validation to show data is handed off accurately and the model cycles through at least one end-to-end run without manual intervention. A brief note outlining what was wrong ...

Project Description My current production workload runs entirely on AWS EC2, and while usage grows, monthly costs are increasing and application response times are degrading. I’m looking for an experienced AWS / DevOps engineer to perform a data-driven infrastructure audit and recommend optimizations. The engagement will begin with a deep-dive assessment of the existing environment, followed by a cost- and performance-balanced architecture proposal. All findings must be supported with measurable evidence, not assumptions. Phase 1 — Infrastructure Audit The audit should cover: EC2 CPU, memory, and disk I/O utilization Database behavior and performance (MySQL) Network flow and latency analysis CloudWatch metrics and logs review Identification of bottlenecks, ...

I run several mission-critical applications on AWS and I’m looking for a seasoned C#/.NET engineer who can extend our backend, shape new APIs, and keep deployments rock-solid. Day-to-day you’ll work with AWS Lambda for serverless jobs and EC2 for long-running services, containerise everything in Docker, then roll it out to our Kubernetes clusters. All data lives in SQL Server, so you’ll need to be comfortable with T-SQL, indexing, and performance tuning. Development happens on Linux, version-controlled with Git, and we sync up during US-CST hours—daily status notes are required so nothing slips through the cracks. Compensation is in the USD 500-1,000 monthly range and can scale with proven results. WPF, Redis, Grafana, or SIP/VoIP expertise would be a welcome ...

I’m ready to launch an e-commerce storefront and need someone who can take the project from blank page to live, fully-tested site that loads quickly and functions flawlessly. The core build must include: • Product search with robust filtering so shoppers can zero in on size, color, price, or other attributes in milliseconds. • A clean review and rating system that feels native to the store, encouraging trust and repeat sales. • Multiple payment gateways (credit/debit, wallets, and at least one local option) configured and verified in both test and live mode. I haven’t locked myself into Shopify, WooCommerce, Magento, or any other stack yet, so if you can justify a platform choice—or even propose a headless solution that outperforms the usual suspects&...

My BMX-lifestyle site, , is built the old-school way—pure HTML, CSS and a touch of JavaScript. I need a developer who can give it a spring-clean so every page loads fast, looks brighter and delivers a smoother ride for visitors. Here’s what I’d like done: • Performance tune-up – audit the current code, compress images, minify and combine files, and add any light-weight caching or lazy-loading tactics that make sense for a static build so pages feel instantly responsive. • Visual polish – keep the bold, bright and colourful vibe but tighten spacing, tweak typography and clean up any inconsistent styling so the overall design feels cohesive. • Subscription button – drop a clearly visible opt-in (Mailchimp, TinyLetter or similar; I&rsqu...

My Linux server is ready, Laravel is in place, and I now need gblicense v15 fully installed, configured, and served through an Nginx reverse-proxy. Default gblicense settings are acceptable; the key requirement is that every feature runs smoothly behind the proxy without breaking existing Laravel routes. What you will do • Compile or obtain the correct gblicense v15 binaries, deploy them to the server, and wire them up to the current Laravel stack. • Configure Nginx as the single entry point, including HTTPS termination (certbot is already available) and clean routing so that gblicense runs on its intended port while remaining invisible to the end user. • Optimise basic network security inside the app and proxy layers (a separate firewall is not planned). • Tro...

We are looking for an experienced developer to build a small Linux utility that communicates with a U.2 NVMe SSD over SMBus (NVMe-MI). The project involves low-level hardware and software work, not application development.

The frontend of the project is done. However, I am unable to integrate Supabase as it crashes when I do. I am not familiar with Supabase. This project has user management, with separate portals for Admin, Interpreter, Client, and Staff. It has various workflows (example: Registration-> User Management; Booking Request-> Job Creation -> Assignment Tracking -> Completion Report -> Invoicing -> Payment) and integrations between users (Admin <-> Interpreter, Admin <-> Staff). It is also important that email integration is seamless.

I have roughly 30 slot game files built entirely with plain HTML, CSS, and JavaScript—no external libraries or frameworks. When I launch them, certain functions refuse to fire and the console fills with both syntax and runtime errors. Here’s what I’ll provide: • Full source folders for each game • Step-by-step reproduction notes • Detailed browser console logs What I need in return: • Clean, well-commented fixes that eliminate the current syntax and runtime errors • Assurance that every game spins, pays out, and resets exactly as designed • Compatibility when hosted locally (e.g., from a simple HTTP server) and when deployed to a public website • A short report outlining what was broken, what you changed, and any best-pra...

I pull live messages (roughly 2 000 users, no media) from one of my own Telegram channels through the raw Telegram API in a Python script, yet every event reaches me several seconds late. That lag ruins the downstream logic I built, so I need another pair of eyes to pinpoint the bottleneck and get as close to true real-time as the API allows. What’s already in place – Python 3.11, Telethon (latest) inside a small async service – Standard getUpdates loop plus a simple database write – No proxy/VPN in between Where I’m stuck Even with a bare-bones handler, the gap between a message appearing in the Telegram client and being processed in my script stays at 4-6 s. I have ruled out network latency and local disk I/O. Your task • Analyse the curren...

I’m working with a Windows batch (.bat) file that has been heavily obfuscated and is now difficult to read or maintain. I need it fully decoded into clean, human-readable form so I can keep using it with confidence. Once it’s legible, the job continues with performance-focused edits: streamline redundant calls, tighten loops, and generally make the script run faster and leaner without changing its core behaviour. Here’s how I see the flow: 1. Deliver a beautified, well-indented version of the original script, with comments that map sections back to the obfuscated source so nothing is lost. 2. Identify and implement performance optimisations—anything from smarter variable usage to consolidated commands—then supply a revised .bat file. 3. Provide a brief chang...

I maintain a Node.js / TypeScript code-base that submits Jito bundles to the Solana network at high frequency. The current version works, yet under heavy load it saturates network bandwidth, slows slot confirmation, and leaves a larger attack surface than I’m comfortable with. I’d like you to jump in, profile the pipeline, and return an implementation that is measurably better across three axes—performance, scalability, and security. What performance means here is simple: bundles must reach the leader faster so more of them land profitably. I’m especially keen on lowering the chatter between my service and Jito’s relays so network bandwidth is used far more efficiently. You’ll have full access to the existing TypeScript modules, aggregator logic, and t...

Our mission-critical stack—OpenShift, WebLogic, and Oracle DB—relies on Dynatrace, yet the current installation is tangled with mis-tuned parameters and component clashes. Configuration issues (incorrect settings and several compatibility quirks) are disrupting reliable monitoring and even nudging performance in the wrong direction. Here’s what I need: an expert hand to inspect every layer of the existing Dynatrace footprint, untangle the bad configs, and re-establish a clean, fully integrated deployment. That includes verifying the Dynatrace Operator on OpenShift, tightening up WebLogic JVM instrumentation, restoring deep-monitoring hooks for Oracle, and confirming all alerting pipelines fire correctly once we’re done. Deliverables • Complete audit rep...

I’m looking for an expert who writes production-ready code with Angular 19+, Signals, NGXS, Angular Material, Reactive Forms, and advanced mixins, and who is equally passionate about explaining the why behind every line. The goal isn’t to build a green-field app; it’s to accelerate a highly motivated senior developer (myself) to the next level through focused, practical learning. What I need from you • Deep-dive guidance on Angular best practices—architecture, performance tuning, and the new Signals mindset. • Hands-on state-management help with NGXS: refin­ing existing stores, adding selectors, and structuring large-scale feature modules. • Advanced Reactive Forms and mixin patterns that keep complex UIs maintainable and testable. &bul...

My current Wix site doesn’t let my promotional videos shine, so the first order of business is an upgrade that delivers cinema-level quality without slowing anything down. Video quality and presentation sit at the top of my priority list, yet speed, optimisation and a polished cross-device experience remain just as critical. What I need you to tackle: • Integrate high-resolution promotional videos on the homepage and selected inner pages, using the best combination of codecs, adaptive streaming, thumbnails and lazy-loading to keep everything fast. • Optimise overall site performance—minify code, compress images, refine fonts and leverage Wix speed tools—so the site scores well on both desktop and mobile. • Refresh the visual design where necessary to...

I have an SSIS package that pulls data from an Oracle database through an connection and loads it downstream for ETL processing. The transfer works, but network-level performance is far below what I need. Here is what I’m looking for: • Diagnose the current ADO.NET-to-Oracle connection, identify any network, buffer, or packet-size bottlenecks, and benchmark the baseline throughput. • Tune the SSIS data flow (buffers, rows per batch, commit size, async settings, etc.) and, if necessary, adjust the Oracle driver or provider configuration. • Provide an updated package or detailed change list so I can reproduce the performance gains in other environments. • Produce a concise report summarizing findings, before-and-after metrics, and next-step recommendations....

I am completing a capstone project that must showcase end-to-end work inside Power BI. The source data sits in SQL Server and is modest in size—well under 10 k rows—so performance tuning will centre on clean Query Folding rather than heavy aggregation tricks. Here is what I need done: • Connect Power BI to the SQL Server instance through Power Query, document each step, and keep every transformation foldable. • Shape and load the tables, then model them with the correct many-to-many relationship where required. Please do this in the Model view so the links are visually clear. • Create essential DAX measures—CALCULATE(), RELATED(), and any supporting columns you find helpful—so the model answers typical summary and slice-and-dice questions. &bu...

I want to move beyond day-to-day administration and master the advanced stack of Oracle Database technologies through live online sessions.

I have a custom-coded site that runs on CorePHP with front-end HTML/CSS only—no page builders, no frameworks to hide behind. Eighteen to twenty pages now crawl along, and they all need to hit a minimum 80+ score on Google PageSpeed Insights for both mobile and desktop so my Google and Facebook ad spend is not wasted. The home page, every product page, and the contact page are the priority, but the remaining pages must meet the same benchmark once we are done. You will be working directly in the raw codebase, so please be comfortable fine-tuning CorePHP templates, compressing and lazy-loading images, minifying CSS/JS, setting correct cache headers, and implementing any server-level tweaks (Gzip, Brotli, HTTP/2, etc.) that make sense. I expect best-practice solutions only—no cos...
