About

I'm a language-agnostic engineer with experience across the stack. My journey began with frontend development, and I'm now deep in the world of backend systems. I primarily work with JavaScript, while staying sharp in Python and actively learning DevOps. I choose stacks by fit — not by familiarity — and care more about correctness, observability, and shipping than about the next shiny thing.

I have had the opportunity to closely work with my senior and colleague at the company, and I can confidently say that he is an exceptional and highly capable engineer. He has made significant contributions across multiple critical areas, including building internal tools that improved overall team productivity, independently handling full-stack development across frontend, backend, and DevOps, and designing the company’s DevOps infrastructure from scratch to ensure scalability and reliability in production systems. He consistently demonstrates strong ownership by taking responsibility for features end to end and delivering high-quality solutions. One of his notable achievements includes developing a career portal that successfully managed over 1200 applications within just one week. He is currently working on a complex multi-tenant CRM system that requires deep architectural understanding and careful system design. In addition, he has shipped multiple production-ready products that are actively used within the company.
