I’m a systems architect and technical leader who ships. With 12+ years building products from concept to scale, my non-traditional path through international business and self-directed learning—including 15+ years living and working across Asia, Middle East and Europe (Singapore, Thailand, Malaysia, China, Iran, UAE, Turkey, Portugal)—has made me stronger: I understand users, markets, and the business impact of technical decisions. I excel at translating complex specifications into working systems—whether implementing WebRTC from RFCs or OIDC/CIBA from standards documents—while building and guiding teams to deliver. I design and build secure, scalable platforms end to end—translating ambiguous business goals into simple, reliable systems. I thrive in high-ownership, fast-moving environments because this is more than a job to me.
