Mindrift: Freelance Full-Stack Web App Developer
Headquarters: Saudi Arabia
URL: http://mindrift.ai
Description
Mindrift is looking for skilled Full-Stack Web App Developers (JavaScript/TypeScript + Python or Node) to join the Tendem project and build interactive browser-based applications within our hybrid AI + human environment. In this role, as an AI Pilot, you'll collaborate with Tendem Agents that handle repetitive tasks, while you provide full-stack engineering expertise, architectural judgment, and quality control to ensure web apps are functional, robust, and ready for real users. This part-time remote opportunity is ideal for professionals with hands-on experience in modern frontend frameworks, backend APIs, databases, and shipping interactive web products end-to-end.
What We Do
The Mindrift platform connects specialists with AI projects from major tech innovators. Our mission is to unlock the potential of Generative AI by tapping into real-world expertise from across the globe.
About the Role
This is a freelance role for a Tendem project. As a Full-Stack Web App Developer, you'll design, build, and refine browser-based applications with real logic, state, persistence, and user input — from habit trackers and budgeting tools to internal dashboards, mini-SaaS tools, and AI-powered apps. You may also work on standalone Python applications and data-processing scripts that sit alongside or behind these products.
Key Responsibilities
- Build interactive web applications with frontend (React, Next.js, Vue, or similar) and a backend API (Python/FastAPI/Flask or Node/Express).
- Design and implement data models, schemas, and persistence layers using SQL (PostgreSQL, SQLite) or NoSQL stores.
- Implement authentication, sessions, and basic role-based access where needed.
- Integrate third-party APIs and AI/LLM services (OpenAI, Anthropic, or similar) into product features.
- Handle state management, user input validation, error states, and loading states cleanly.
- Build standalone Python tools and scripts where required by the task (data processing, API clients, lightweight backend utilities).
- Evaluate AI-generated full-stack code and refactor it for correctness, security, performance, and maintainability.
- Write clear, testable code and debug end-to-end issues across frontend, backend, and database.
Requirements
- At least 3 years of relevant experience in full-stack web development or shipping interactive web applications (required).
- Bachelor's or Master's Degree in Computer Science, Engineering, Information Technology, or related technical fields is a plus.
- Strong foundation in full-stack web development, modern frontend frameworks, backend architecture, and building interactive browser-based applications end-to-end.
- Strong command of JavaScript/TypeScript and at least one modern frontend framework (React, Next.js, Vue, Svelte, or similar).
- Solid backend experience in Python (FastAPI, Flask, Django) and/or Node.js (Express, NestJS).
- Hands-on experience with relational databases (PostgreSQL, MySQL, SQLite) and basic schema design.
- Experience implementing REST APIs, request validation, error handling, and authentication flows.
- Familiarity with deployment platforms (Vercel, Netlify, Render, Fly.io, Railway, or similar).
- Experience integrating LLM APIs or other AI services into product features is a strong plus.
- Comfortable with version control (Git) and basic testing practices.
- Strong attention to detail and commitment to building working, robust products.
- Self-directed work ethic with the ability to architect, build, and ship features independently.
- Portfolio of shipped web applications (required).
- English proficiency: Upper-intermediate (B2) or above (required).
Project Time Expectations
Tasks are estimated to require around 10–20 hours per week during active phases, based on project requirements. This is an estimate, not a guaranteed workload, and applies only while the project is active.
Compensation
On this project, contributors can earn up to $60 per hour equivalent, depending on their level and pace of contribution. Compensation varies across projects depending on scope, complexity, and required expertise.
