About Me

Building the future of distributed systems

A seasoned engineer passionate about creating scalable, efficient, and reliable backend systems

My Journey

Over the past 5 years, I've evolved from a Junior Software Engineer to a Senior Backend Engineer, specializing in cloud infrastructure and DevOps practices.

My most significant achievement was spearheading a strategic migration from cloud providers to self-hosted infrastructure, resulting in a 75% cost reduction while maintaining enterprise-grade reliability.

I'm passionate about mentoring developers, optimizing system performance, and building resilient distributed architectures that scale.
