FOCUS
Useful AI, not AI for show
I enjoy turning complex problems into simple, deliberate systems that make a real difference — especially where software engineering and applied AI meet.
My background spans enterprise integration, RAG systems, computer vision and full-stack product work. The common thread is understanding the system deeply enough to make the solution feel straightforward.
06 / LET'S BUILD SOMETHING GREAT
Good ideas start with a conversation.
If you're building something ambitious, solving a messy systems problem, or exploring where applied AI genuinely helps, I'd be happy to talk.
