Freelance Full-Stack Web App Developer

This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Freelance Full-Stack Web App Developer in India.

This role offers the opportunity to build and refine interactive, production-ready web applications in a hybrid environment where human engineering expertise is combined with AI-assisted development workflows. You will work across the full stack, developing both frontend interfaces and backend systems for real-world tools such as dashboards, SaaS-like applications, and data-driven web products. The position requires strong architectural thinking, as you will be responsible for ensuring code quality, performance, and maintainability across complete application flows. You will collaborate in a flexible, remote freelance setup, contributing to fast-paced, iterative development cycles. The environment is highly technical and innovation-driven, requiring independence, precision, and problem-solving skills. This is an opportunity to work at the intersection of software engineering and AI-enhanced development.

Accountabilities:

In this role, you will be responsible for designing, building, and improving full-stack web applications while ensuring reliability, scalability, and clean architecture across all components.

  • Develop interactive web applications using modern frontend frameworks (React, Next.js, Vue, or similar)
  • Build and maintain backend APIs using Python (FastAPI, Flask) and/or Node.js (Express, NestJS)
  • Design and implement data models and persistence layers using SQL or NoSQL databases
  • Develop and integrate authentication systems, sessions, and role-based access when required
  • Connect third-party APIs and AI/LLM services into application features
  • Manage application state, validation, error handling, and loading states across the stack
  • Create standalone Python scripts or tools for data processing or backend utilities
  • Review, debug, and refactor AI-generated code to ensure correctness, security, and performance
  • Write clean, testable code and resolve end-to-end issues across frontend, backend, and database layers
  • Contribute to the full lifecycle of feature development from design to deployment
Requirements:

This position requires strong full-stack development experience and the ability to independently design, build, and ship complete web applications.

  • Minimum 3 years of experience in full-stack web development or building production web applications
  • Strong proficiency in JavaScript/TypeScript and at least one modern frontend framework
  • Solid backend experience with Python (FastAPI, Flask, Django) and/or Node.js (Express, NestJS)
  • Experience with relational databases (PostgreSQL, MySQL, SQLite) and schema design
  • Strong understanding of REST APIs, authentication flows, and error handling
  • Experience with Git version control and basic testing practices
  • Familiarity with deployment platforms (Vercel, Netlify, Render, Railway, or similar)
  • Ability to work independently and architect end-to-end solutions
  • Strong attention to detail and commitment to production-quality code
  • Upper-intermediate English proficiency (B2 or above)
  • Portfolio of shipped web applications (required)

Nice to have:

  • Experience integrating LLM or AI-based APIs into applications
  • Experience building AI-assisted or data-driven products
  • Background in advanced architecture or scalable system design
  • Experience with performance optimization and security best practices
Benefits:
  • Remote freelance work with flexible schedule (task-based 10–20 hours/week estimate)
  • Competitive compensation up to $35/hour equivalent, depending on experience and contribution level
  • Opportunity to work in a hybrid AI + human development environment
  • Hands-on experience building AI-integrated, production-grade web applications
  • Exposure to modern full-stack workflows and advanced engineering challenges
  • Performance-based opportunities for additional rewards and bonuses
  • Work independently with full ownership of features and technical decisions
  • Global, remote collaboration environment
