...UI clips to showcase two things: • the clean, intuitive user interface and overall visual design • the technical functionality that makes everyday workflows smoother The end goal is a crisp explanatory video that immediately shows potential users what they can expect the moment they log in—no fluff, just clear feature highlights in motion. If you feel an occasional 2D or 3D accent would amplify a scene, let’s discuss, but the backbone must remain kinetic typography. I’ll supply brand guidelines, color codes, logo assets, and short screen recordings. From you I’ll need: 1. A brief concept or storyboard so we agree on pacing and key callouts 2. The finished video in HD (and a version optimized for social feeds) 3. Source project file...

I need an experienced Python engineer who works confidently with AWS Glue to build and manage a small suite of data-integration jobs for a Hyderabad-based project. The core of the work is to design and automate Glue ETL pipelines that pull data from our production databases, catalog it accurately, and transform it into analytics-ready tables. Here is what I expect from the engagement: • Develop, test, and deploy Glue ETL jobs in Python. • Populate and maintain the Glue Data Catalog so new tables are discoverable and properly version-tracked. • Implement efficient transformation logic that cleans, enriches, and partitions data for downstream reporting. • Optimise job performance and cost by selecting the right worker types, job parameters, and database co...

...we will wire in automated campaigns, broadcasts, and transactional flows that talk to the existing user database. I am still weighing the provider, with AWS EUM and Twilio at the top of the list. If you have a smarter alternative I’m open, but I expect you to be fully comfortable with either of those stacks and the surrounding data science needed for deliverability, tracking, and optimisation. A full-stack mindset is useful because you’ll be touching both the messaging layer and the web application that triggers it. Key deliverables • 10DLC setup, brand and campaign registration approved • API integration with the chosen provider (AWS EUM or Twilio) for SMS and email • Template and workflow automation that can be managed from our admin UI...

We are looking for an experienced DNS and domain reputation specialist to help resolve an ongoing production issue affecting users on certain mobile networks (specifically T-Mobile). The specific error users see is: DNS_PROBE_FINISHED_NXDOMAIN Our platform is hosted on AWS (Route 53 + ALB / CloudFront). DNS is correctly configured and resolves properly on most networks (Google DNS, Quad9, etc.). Our domain reputation has already been reviewed and corrected by major security providers. However, users on T-Mobile are still experiencing DNS-based blocking or resolution issues. This appears to be related to carrier-level DNS filtering or residual reputation/security classification behavior — not core infrastructure misconfiguration. ⸻ Scope of Work • Diagnose carrier-le...

I’m ready to amplify my brand’s presence across Facebook, Instagram, and Twitter and I need a skilled digital marketer who can own the entire process. My priority is brand awareness, so every touchpoint—from the tone of voice to the hashtags you choose—should reinforce recognition and recall. What you’ll handle day to day is crafting engaging written posts that suit each platform’s nuances, scheduling them for maximum visibility, and actively monitoring comments and messages to keep the conversation flowing. A thoughtful content calendar, clear copy guidelines, and on-brand visuals or curated images that complement the text will all be part of your remit. To keep us aligned, I’d like: • A two-week content plan delivered up front (post...

...signals action without turning into visual noise. The mood I’m after is unmistakably action-packed: bold poses from in-game characters up front, dramatic explosions or particle blasts behind them, and a neutral, well-balanced colour palette that keeps the scene readable even on small screens. What has to be there: • Character images as the clear focal point • Explosions or similar effects to amplify movement and tension • A balanced mix of greys, whites, and muted accent colours so the brighter effects pop Weapons are optional accents if they support the composition, but they shouldn’t compete with the characters and explosions. Deliverables: • 1280 × 720 px thumbnail in PNG or JPG, under 2 MB • Layered PSD (or AI) so I can edit...

I have the complete source code for BDonor, a live web-app that is currently down because Clerk Auth hit its “100 user limit.” The break means I can’t even reach the admin panel, so I need a clean redeployment from the ground up. Right now the site is hosted on Vercel, but I’m open to keeping it there or shifting to something like AWS or Google Cloud if that would eliminate the Clerk ceiling and future-proof the project. I’m not certain which environment variables, build flags, or third-party hooks are mission-critical, so I’ll rely on your guidance to audit the repo, document what matters, and carry it over correctly. Key objectives • Spin up a fresh production instance under my own new accounts (hosting, auth, database, any other services...
