Gathering my backend expertise...
Backend Developer specializing in scalable systems.
I’m a Backend Developer with strong experience in building scalable, secure, and high-performance backend systems using Node.js, NestJS, Python, FastAPI, and TypeScript.
My work focuses on designing robust RESTful APIs, managing databases such as PostgreSQL, MongoDB, and Redis, and building real-time features, background processing, and AI-powered services. I take pride in writing maintainable, production-ready code and building systems that scale reliably.
Contributing to the backend of a large-scale, configurable microservices system.
Built real-time logistics and trip tracking systems (Uber-style) with dynamic route updates, multi-party coordination, and weather-aware routing.
Contributed to the development of 20+ production websites within a large-scale monorepo architecture.
