I’m a backend developer with strong experience in Node.js, TypeScript, and building scalable microservices using NestJS, Express, and MongoDB/PostgreSQL. I’ve worked across domains like fintech, SaaS, and enterprise systems, handling API design, authentication (JWT/OAuth), and performance optimization.

I’ve also worked with AWS (EC2, S3, ECS), Kafka/RabbitMQ for event-driven systems, and have exposure to CI/CD pipelines and Docker-based deployments. I enjoy solving system design problems and building reliable, high-performance backend systems.

Right now, I’m looking for a backend or full-stack backend-focused role where I can contribute to scalable product development, work on system architecture, and grow in a strong engineering team.
