Freelance Full-Stack Web App Developer

Mindrift is seeking experienced Full-Stack Web App Developers (JavaScript/TypeScript + Python or Node) for a part-time remote freelance role to develop interactive browser-based applications within a hybrid AI + human environment, collaborating on the Tendem project.

Location: Remote

Salary: Up to $35 per hour

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
• Bachelor's or Master's Degree in Computer Science, Engineering, Information Technology, or related 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 — not demos
• Self-directed work ethic with the ability to architect, build, and ship features independently
• Portfolio of shipped web applications
• English proficiency: Upper-intermediate (B2) or above

Benefits

• Work fully remote on your own schedule with just a laptop and stable internet connection.
• Gain hands-on experience in a hybrid environment where human expertise and AI agents collaborate.
• Participate in performance-based bonus programs that reward high-quality work and consistent delivery.
