Senior backend engineer specializing in Node.js/NestJS microservices, scalable APIs, and secure authentication.
BangladeshWhat I'm looking for
I’m a Full Stack(Backend Focus) Engineer with 5+ years of experience designing and scaling production-grade systems using Node.js, NestJS, and TypeScript. I focus on microservices architecture, high-performance APIs, and distributed systems, with deep expertise in database optimization, messaging systems (Kafka, RabbitMQ), and secure authentication (OAuth 2.0, JWT, Clerk). In recent roles, I’ve improved API performance through query optimization, database indexing, and caching, and I’ve led backend architecture decisions in fast-paced, remote-first environments.
As a Senior Backend Engineer, I’ve designed and deployed microservices that handle high-volume daily requests, implemented event-driven processing, and strengthened authentication and authorization. I also enjoy turning requirements into scalable backend modules—whether building event booking seat-management services, RBAC-based directory and SaaS platforms, or multi-role e-commerce backend systems—while mentoring junior developers and maintaining clean, maintainable architecture.
