I’m a full-stack developer with a strong focus on backend engineering, cloud infrastructure, and scalable system design. I specialize in building production-ready web applications, APIs, and distributed systems that are reliable, secure, and built to scale.

I don’t just write code — I design systems that solve real problems.

What I do best
. Build robust backend systems using Node.js, Express, PostgreSQL, and Prisma
. Design REST APIs with proper validation, authentication, and rate limiting
. Architect scalable cloud solutions on AWS (S3, ECS, Lambda, SQS, CloudFront)
. Implement caching, background jobs, and async workflows using Redis
. Develop modern full-stack applications with React, TypeScript, and clean UI architecture

Real-world experience
. I’ve built and shipped a production-grade platform that includes:
. Cohort and group management with role-based access
. Secure authentication (OAuth, JWT)
. High-concurrency APIs with caching and DB optimization
. An event-driven video processing pipeline using Docker, FFmpeg, AWS ECS, Lambda, and SQS
. Secure media delivery via CDN using signed URLs / cookies

This means I’m comfortable working on non-trivial systems, handling edge cases, failures, and performance bottlenecks.

How I work
. I focus on clean architecture and maintainable code
. I ask the right questions before coding
. I communicate clearly and give regular updates
. I think in terms of scalability, cost, and long-term maintainability

Tech Stack
. Backend: Node.js, Express, PostgreSQL, Prisma, Redis
. Frontend: React, TypeScript, Vite, Zustand, Tailwind CSS
. Cloud & DevOps: AWS (S3, ECS, Lambda, SQS, CloudFront), Docker
. Other: FFmpeg, REST APIs, OAuth, JWT, Zod, CI/CD, AI Agents, RAG pipelines

Ideal projects
. Full-stack web applications
. API development & system design
. AWS architecture & cloud automation
. Performance optimization & refactoring
. Startups or teams looking for a reliable long-term developer

If you’re looking for someone who can own features end-to-end, write clean code, and think beyond just “making it work,” let’s talk.
