About

Repeat founder with 10+ years building products. Now focused on AI - the practical applications that create real value, not the hype. Documenting everything in real-time.

Journey

10+ years building full-stack products β€” from e-commerce platforms to SaaS tools. Started multiple companies, shipped features used by thousands, learned what separates ideas from execution.

Now I'm focused on building AI products. Not chasing trends, but solving real problems: How do we build AI tools people actually use? What makes an AI product sticky vs. a demo? I'm building, testing, and documenting everything.

This blog is my lab notebook. AI implementation patterns, product decisions, technical deep-dives, startup lessons β€” raw and unfiltered. If I learned it the hard way, you'll find it here.
