    I need a full-stack build for a new e-commerce website. The flagship feature is a lightning-fast product catalogue with robust search and filtering so visitors can narrow thousands of SKUs in just a few clicks.

To move forward, send me a detailed project proposal that covers: • Your proposed tech stack and hosting approach • The method you’ll use to deliver the search/filter experience (faceted search, full-text indexing, Elasticsearch, etc.) • Milestones with clear timelines and deliverables • Links to live e-commerce sites you’ve built that showcase similar functionality Clean, well-documented code in Git...

The finished site must feel just as fast as the current demo, but with production-ready code and a modern tech stack you are comfortable supporting.

I am open to adding Google OAuth as an extra convenience once the primary flow is solid. • Full e-commerce layer: product catalogue, flexible pricing, shopping cart, checkout, order history and a basic admin to add or edit products.

    For my final-semester project I need a fully functional restaurant website that feels modern and clean from the first click. The core pages should showcase the menu in an appetising, easy-to-navigate layout, collect customer reviews that can be moderated from a simple back-end, and allow visitors to book a table through an online reservation form (email notification is enough; full booking engines are welcome if you already have one). Because this is an academic submission, clear documentation is almost as important as the code itself: a brief read-me explaining folder structure, any frameworks or libraries used, and instructions to spin the project up locally will be required with the final hand-off. Responsive behaviour across common breakpoints is essential so I can demo it on both des...

    I need a web-based administrative panel that lets me oversee several IPv4 proxy servers running 3Proxy from one place. The panel should: • Auto-configure new or rebuilt servers, applying 3Proxy settings and firewall rules without manual SSH work. • Push software updates, configuration edits, and security patches to every connected host remotely. • Expose a documented RESTful API so other systems can create, suspend, rotate, or delete proxies programmatically. • Support multiple user roles—at minimum Admin plus one or more limited roles—with a clean permissions model. • Display real-time status (online/offline, traffic, errors) and basic analytics for each proxy. A straightforward, responsive UI is essential; think login, dashboard, server list...

    I’m preparing a migration from our Sapiens ID3 platform into the FAST Technology system and need a precise field-by-field mapping created. The source data centers on policy records, and I must be sure that every element tied to the customer—name and contact details, policy-specific attributes, and related transaction history—lands in the correct destination tables in FAST. Right now each field is stored in ID3’s proprietary format. I will supply sample extracts as well as the FAST data dictionary; your task is to analyse both structures, match every like-for-like field, and flag any gaps where a transformation or new target field is required.

    I need a reliable ABAP developer who can slot straight into my backlog and keep the sales (SD) side of our SAP system moving. Day-to-day work will swing from creating or extending tables and views in the Dictionary to building ALV-driven reports, tweaking module-pool screens, and coding OO-ABAP classes.
