What I'm looking for

I’m looking for a backend-focused role where I can own API architecture and shipping end-to-end SaaS features. I want a team that values security, performance, clean design, and fast iteration with real user feedback.

I’m a freelance backend developer and independent full-stack engineer building production SaaS products end-to-end. I focus on system design, API architecture, reliable deployments, and user feedback to turn ideas into shipped features.

In my current role, I engineered 4 production SaaS platforms serving 50+ users using Node.js, Express.js, MongoDB, PostgreSQL, and REST API architecture. I led the full product lifecycle—design, API structure, deployment, and iteration—and integrated 5+ third-party APIs (Stripe, Razorpay, Gemini, Cloudinary) to reduce integration time by 35% per release.

I also care deeply about performance and correctness: I optimized state management with Zustand, Redux Toolkit, and React Query to cut redundant API calls by 40% across Next.js frontends, and strengthened API security with HTTP-only JWT, RBAC, Helmet.js, rate limiting, and XSS sanitization. Alongside product work, I contribute to open-source and expand my stack with Drizzle ORM, NeonDB, LangChain, and TensorFlow.js for AI-powered applications.
