Kishan
About this gig
Are you looking for a full stack developer who can build secure, scalable, and production-ready web applications?
I develop full stack applications using React for the frontend and FastAPI (Python) for the backend, with strong database integration and clean system design.
I have worked with both self-hosted and managed database services such as Supabase (PostgreSQL) and MongoDB Atlas to ensure reliability, scalability, and easier maintenance in production environments.
Skills & Tech Stack
- Frontend: React.js (modern UI, responsive design)
- Backend: Python FastAPI (REST APIs, async development)
- Databases: PostgreSQL, MongoDB
- Cache / performance: Redis (when required)
- Deployment: Docker, Nginx, VPS hosting
- API integration and system design
Security & Production Practices
Security is always a priority in my development process. I implement:
- JWT authentication using HTTP-only cookies
- Role-Based Access Control (RBAC) for user and admin systems
- Secure API design with proper validation
- Protected routes and authorization layers
- Environment-based configuration for safe deployments
