About

I am a Senior Software Engineer with more than a decade of experience building scalable web systems and distributed architectures.

Currently contributing at enterprise scale, I specialize in Golang, microservices architecture, Kubernetes, Redis, and Elasticsearch. My focus is on reliability, performance optimization, and system scalability.

Beyond engineering, I founded Santekno — a technology education platform where I share practical tutorials and insights to help developers grow and innovate.
