I’m a Backend Developer with around 2 years of professional experience designing and developing Node.js/NestJS APIs for financial, e-commerce, and payment systems. I started as a self-taught developer in 2023 and grew through continuous learning, solving technical challenges, and building practical projects.

In my recent work, I’ve built backend services for retail ERP/POS, a closed-loop credit payment platform, and B2B/B2C wholesale marketplace using NestJS and Prisma with PostgreSQL. I focus on stable, maintainable, and testable services—implementing authentication with secure session management, role-based access control (RBAC), RESTful APIs, and microservices patterns (including RabbitMQ queues, Redis caching, and clear error handling). I also prepare services for staging deployment and collaborate on final testing in production-like conditions.
