About me
Intro
Software engineer turned founder with 8+ years building products that actually ship. Specialized in fintech and AI systems. Built multiples SaaS companies from zero to acquisition. I balance technical depth with business reality - code that scales, features customers actually use, and infrastructure that doesn't break the bank. Big believer in starting simple. If it doesn't solve a real problem for real users willing to pay real money, it's not a good idea.
