What I'm looking for

I’m looking for a role where I can build scalable backend services and RESTful APIs, own authentication/security, and improve performance in an agile team using modern cloud and container tooling.

I am an experienced Node.js Developer with 5 years' expertise in designing and maintaining scalable backend applications and RESTful APIs. I’m proficient in Node.js, Express.js, and NestJS, and I focus on delivering reliable software solutions in agile environments.

I build RESTful APIs and microservices architectures, implement authentication and authorization with JWT and OAuth, and design/optimize MongoDB and PostgreSQL databases. I also integrate third-party APIs and payment gateways, and develop real-time applications with Socket.IO.

I deploy and manage applications using Docker and AWS, improving performance, scalability, and security. Across Go, Python, C#, and PHP projects, I’ve consistently delivered secure, maintainable services and production-ready systems.
