What I Do
A disciplined approach from architecture to deployment.
I design scalable microservices and REST APIs using NestJS, Spring Boot and Node.js — with async messaging, SOLID principles, and clean architecture for long-term maintainability.
I build complete products end-to-end: backend APIs, web interfaces with React and Next.js, and mobile apps with Flutter — covering the full lifecycle from database schema to UI.
I deploy services on AWS, Railway and Docker, integrate payment gateways, and connect complex systems with event-driven patterns and RabbitMQ for reliable async processing.
