What I'm looking for

I'm seeking a Backend Engineer Internship at Metasys, where I can deliver reliable API microservices, transactional domain logic, and high-performance backend systems.

At W3 Engineers Ltd, I developed, refactored, and maintained production RESTful backend services using Node.js and Express.js, following clean architecture and modular separation of concerns. I also designed PostgreSQL schema migrations and optimized queries for dependable data retrieval.

In my projects, I built backend systems for event management, collaborative classrooms, and mobile banking. This work includes RBAC, Prisma-based relational data models, JWT authentication, and transactional logic with ACID data integrity.
