Senior Backend Engineer with 8+ years architecting high-throughput distributed systems from thousands to millions of daily requests. Expert in Node.js, TypeScript, NestJS, and cloud-native infrastructure. Proven track record integrating Gen-AI to drive 95%+ efficiency gains.
I'm a Senior Backend Engineer with 8+ years architecting high-throughput distributed systems, handling 2M+ requests/day across Node.js, TypeScript, NestJS, PostgreSQL, Kafka, Docker, and Kubernetes. I've worked across product teams, leading engineering initiatives and building systems for real-world business workflows.
My expertise spans TypeScript, Node.js, NestJS, Express, Fastify, REST APIs, GraphQL, microservices, PostgreSQL, MongoDB, DynamoDB, Redis, AWS, GCP, Docker, Kubernetes, Kafka, and CI/CD. I also integrate OpenAI, Claude, and Gemini into production 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.
