What I'm looking for

I’m looking to build scalable, fault-tolerant backend systems—especially Go microservices with Kafka-style event flows—where I can own system design, concurrency, and reliability. I value clear service boundaries and pragmatic engineering for fast delivery.

Software Engineer with hands-on experience in backend development, distributed systems, and full stack web applications. Specialized in Golang and Node.js/NestJS with strong foundations in event-driven microservices, Kafka, Redis, and cloud-based deployments on AWS. Built high-performance systems including distributed processing pipelines, reverse proxy cache servers, and multi-tenant SaaS platforms. Comfortable working across the stack with React and Next.js on the frontend.
