About Me

Solutions Engineer with 3 production AI systems shipped in fintech — RAG pipeline, agentic SMS automation, and vector-search knowledge base. Full pre-sales cycle (discovery through POC) for 20+ enterprise partners, plus Stripe Connect architecture and SOC 2 compliance implementation.

Started in QA (yes, I found all the bugs), pivoted to solutions engineering, and now I'm deep in the AI/ML space building production systems. I believe in never stopping learning — and moving fast while doing it.
