You’ll be doing real full-stack work, not simulated exercises, so the code you write will ship to production. Most of your day will revolve around hands-on web development. On the front end you’ll craft responsive views with HTML, CSS and JavaScript, then wire them up with either React JS or Angular—whichever you’re most comfortable with.

    I need an end-to-end AI solution that can locate, filter and deliver up-to-date scientific studies to research fellows on demand. The core idea is simple: a user enters a topic, keyword, DOI or even an abstract snippet and instantly receives the most relevant peer-reviewed papers, neatly ranked with key metadata and brief AI-generated summaries. To make that happen, the tool should draw from open databases such as PubMed, arXiv, Crossref and any other free or licensed sources you recommend, then apply NLP techniques—semantic search, named-entity recognition, topic clustering—to surface only the most pertinent results. A clean web interface or a lightweight desktop app is fine; what matters is accuracy, speed and an intuitive workflow for researchers who will be using it daily....

    I’m ready to build a brand-new mobile application and need one partner who can handle the entire full-stack effort from first commit through store release. The project starts at concept stage, so you’ll help shape both the client-side experience and the server-side architecture. On the front end, I’m open to native or cross-platform approaches (React Native, Flutter, Swift/Kotlin, etc.) as long as the result is smooth, responsive, and ready for iOS and Android distribution. Server-side work includes selecting the tech stack, designing the database, creating secure REST or GraphQL APIs, and setting up cloud deployment with basic CI/CD. Key deliverables • Fully coded mobile app (iOS & Android) • Production-ready backend, database, and API documentation &...

    I already have an unfinished application that needs attention in four intertwined areas: Frontend UI/UX, Backend server logic, AI model enhancement, and the overall move toward a reliable SaaS offering. The existing code base is functional but fragmented; the original developer left limited documentation and I’m not completely sure which tech stack was finally chosen. You’ll start with a brief audit of the repository to identify the frameworks and libraries in place, then recommend whether we keep, refactor, or replace any layer. Frontend • Polish the current interface, improve component structure, and ensure responsive behaviour across desktop and mobile. • I’m aiming for a friendly, modern look—feel free to leverage React, Angular or Vue once you co...

    >> Senior Integration Developers & Workflow Automation Engineers (Multiple Hires) - >> Project Overview We are the core engineering team behind RailCall, a governance-first automation layer for AI-driven workflows. Every action an AI agent takes on our platform goes through a strict `preview -> approve -> execute -> signed receipt` loop (the "cryptographic airlock"), ensuring enterprise-grade security. We are currently expanding our ecosystem and are looking to hire multiple talented developers to build local-first agent tools, UX upgrades, and integration workflows on the RailCall Engine. We have a total budget of $5,000 allocated for this phase of development, and we will be awarding contracts to the best developers across four specific tracks. ->...

    I have several real interviews for full-stack software engineer positions in the tech industry coming up soon, and I want to rehearse under conditions that feel as close as possible to the real thing. I’m looking for someone who has actually hired, managed, or technically screened full-stack developers—ideally with recent experience across both frontend (React/TypeScript, modern CSS) and backend (Node.js/Express, REST/GraphQL, SQL/NoSQL, basic cloud design). Here’s how I picture the engagement: • We meet on Zoom or a comparable video platform for two separate 60-minute mock interviews. • Each session mirrors a standard technical loop: a brief resume deep-dive, a live-coding algorithm/problem segment, and a discussion of system or API design that probes scala...

    I need a seasoned full-stack developer to take my concept for a job-sales website from idea to production. The core of the build is an intuitive admin panel where I can create, edit, sort and eventually archive job listings. On the front end, candidates (or buyers) must be able to register with a standard email-and-password flow, manage their profiles, review past orders, and track their applications. Payments will run through both Stripe and PayPal, so the checkout flow, webhooks, and order recording all need to be airtight and PCI-compliant. A smooth, responsive UI is non-negotiable; phone, tablet, and desktop users should all enjoy the same polished experience. Beyond the basics, two extras are important to me: • An internal application-tracking view so I can follow each candidat...

    I need a full-featured corporate job portal built from the ground up. Because we do not yet have formal branding guidelines, you will have creative freedom on the look and feel as long as the result is clean, professional, and consistent across desktop and mobile. Core features I must see on launch: • Employee profiles • Job postings with robust search filters • End-to-end job application tracking (from application to hire) A simple admin dashboard for posting roles, approving profiles, and pulling basic hiring reports is expected as part of the delivery. I’m open to your preferred stack—popular choices such as Laravel, Django, Node, React, or similar frameworks are all fine—as long as the final code is well-documented and easy for an in-house tea...
