I build products that work in the real world – from coffee brands sold in local stores to AI systems powering enterprise platforms.
At 19, I launched BREW-N-FILL® and personally onboarded with local retailers. That taught me business isn't about ideas – it's about execution, compliance, and trust.
Now I bring that same mindset to technology: I've architected API platforms on Google Apigee, built RAG-powered LLM chatbots with LangChain, and shipped production systems that handle real traffic.
