What I'm looking for

I seek backend roles building scalable, secure services with strong CI/CD, cloud deployments, and opportunities to mentor and improve system performance.

I am a Backend Developer with over six years building scalable Node.js/NestJS services, REST APIs, and CI/CD pipelines, focused on performance and reliability. I have a proven record of optimizing databases (PostgreSQL, MongoDB) and leading microservice migrations to reduce maintenance overhead.

In recent roles I boosted production system performance threefold through indexing and caching, integrated secure APIs with central banking systems, and implemented Dockerized AWS deployments using ECS, Lambda, and S3. I also build API documentation with Swagger and automate releases with GitHub Actions.

I mentor junior engineers, advocate clean architecture and testing best practices, and seek roles where I can design modular, event-driven systems, improve system observability, and help teams deliver secure, high-performance backend platforms.
