I build scalable, production-ready backends using Node.js and NestJS, along with Python and FastAPI when it fits the problem. TypeScript keeps everything predictable, maintainable, and safe as systems grow.
I design data layers with PostgreSQL, MongoDB, and Redis, and build APIs that stay reliable under real-world load. I also integrate real-time systems, background jobs, and AI-powered features when they add real product value.
For larger systems, I design microservices with clear boundaries and maintainable communication patterns. Whether it’s modular monoliths or distributed systems, I focus on keeping complexity under control.
I understand frontend concerns from past experience, which helps me design better APIs around real UI needs like pagination, loading states, and error handling. My focus is backend, but I build with the full product in mind.
I ship systems to production using Docker, CI/CD pipelines, and cloud infrastructure. From deployment to runtime, I focus on stability, observability, and systems that are easy to debug when things go wrong.
My professional progression through backend engineering, system architecture, and technical leadership.
I focus on backend systems and getting them to production reliably. Here's a snapshot of the stack I use most, especially APIs, data, and delivery.
