What I'm looking for

I seek backend or full-stack roles where I can build scalable APIs, work with microservices and payments, and improve reliability through CI/CD and monitoring.

I am a backend developer focused on building scalable, reliable services using Node.js, NestJS, and PostgreSQL. I design APIs, optimize database schemas, and implement CI/CD and automated testing to ensure smooth deployments and high availability.

I've built transportation, routing, tipping, and in-app purchase systems, integrating mapping APIs and payment platforms for Apple and Google. I have experience with microservices, event-driven patterns, Redis caching, and message brokers to support real-time operations.

I collaborate effectively with cross-functional teams to deliver performant full-stack solutions, and I prioritize maintainability, monitoring, and performance optimization in every project.
