About Me

I'm a Senior Backend Engineer with 7+ years of experience scaling high-throughput systems from thousands to millions of daily requests. I've worked across startups and enterprise-level products, leading teams and architecting systems that power real-world business growth.

My expertise spans Node.js, TypeScript, NestJS, PostgreSQL, and cloud-native infrastructure including Docker, Kubernetes, AWS, and GCP. I specialize in building microservices, optimizing database performance, and integrating Gen-AI (OpenAI, Claude, Gemini) to drive 95%+ efficiency gains in critical workflows.

When I'm not coding, you'll find me exploring new technologies, contributing to open-source projects, or sharing knowledge through technical blogs. I believe in continuous learning and staying updated with the latest trends in backend development and AI.
