I’m a full-stack product engineer with 10 years of experience shipping production software in regulated health-tech, logistics, and agency delivery environments. I build end-to-end features from ambiguous requirements through design validation, stakeholder alignment, and frequent releases—often where compliance, data accuracy, and reliability matter. I also create LLM-powered tools and agent workflows as part of my day-to-day development, and I work comfortably with both technical teams and customers thanks to my earlier career in frontline sales, negotiation, and client management. Whether I’m integrating real-world device protocols, unifying complex data into clean APIs, or speeding up delivery with internal AI tooling, I focus on practical outcomes and smooth adoption for real users.
