About Me

I build systems that bridge the gap between infrastructure and intelligence.

With over 6 years managing complex IT ecosystems across 12 companies, I've developed a deep understanding of what it takes to keep production systems running reliably. Managing everything from Windows and Linux servers to network architecture and database administration taught me one critical lesson: the best technology is invisible when it works.

Over the past year, I've channeled that operational mindset into AI engineering — designing and deploying production RAG systems, building AI-powered applications, and integrating LLMs into real business workflows. I don't just prototype; I ship systems that handle real data, for real users, at scale.

I'm driven by the challenge of taking complex problems and engineering elegant, maintainable solutions — whether that means orchestrating AI agents or architecting server infrastructure.
