What I'm looking for

I seek roles building scalable AI-enabled full-stack systems in collaborative, engineering-driven teams where I can lead architecture, mentor engineers, and deliver measurable product impact.

I am a Senior Software Engineer and AI specialist with over nine years of experience designing full-stack, cloud-native systems and production AI solutions. I have led development of scalable microservices, multilingual AI chatbot platforms, and no-code tooling while improving deployment cadence and operational efficiency for enterprise clients.

My work spans backend and frontend engineering, DevOps, observability, and mentoring teams to raise engineering standards. I deliver secure, high-performance products across fintech, HR, and industrial automation, and I focus on pragmatic architecture, automation, and measurable business impact.
