About

As a Backend Developer with 5+ years of experience, I specialize in Node.js, Golang, TypeScript, and microservices, building cloud-native, scalable distributed systems for fintech, e-commerce, and logistics. I have strong expertise in AWS (EC2, Lambda, S3, SQS, API Gateway), PostgreSQL, MongoDB, Redis, Docker, Kafka, and robust CI/CD pipelines. I focus on clean architecture, system design, and performance optimization to deliver secure REST APIs and high-availability services.

I thrive in collaborative Agile environments, continuously learning and mentoring others, and I am ready to contribute to complex technical challenges while ensuring reliable delivery and maintainable code.
