I am a Senior Full Stack Engineer dedicated to building scalable, high-performance web applications. With deep expertise in the TypeScript, Python and Java ecosystem, I bridge the gap between responsive user interfaces and resilient backend architectures.
My professional journey is defined by end-to-end delivery. From designing database schemas and optimizing server-side logic (Node.js/NestJS/Python/Java/Springboot) to crafting pixel-perfect, intuitive frontend experiences (React/React Native), I manage the full lifecycle of complex software products.
I don't just write code; I engineer solutions. Whether optimizing legacy systems for speed or architecting new platforms for high concurrency, my focus is always on reliability, maintainability, and clean code. I have a proven track record of delivering mission-critical systems in dynamic environments, ensuring stability even under heavy load.
