What I'm looking for

I’m looking for teams that value ownership and correctness—especially in regulated environments—where I can build backend/API and event-driven systems, ship reliably with strong audit trails, and collaborate across product, QA, and customers.

I’m a Senior Software Engineer and former founder/CTO with 17 years across software, data, and product delivery. I’ve built production systems in high-accountability environments—banking BI for Ailos, healthcare/life-sciences regulatory intelligence at Redica Systems, and a founder-led SaaS processing 4M receipts/day.

I bring practical ownership, backend/API depth, event-driven architecture, and a strong auditability mindset in regulated industries. My work blends Python/FastAPI microservices, PostgreSQL/Oracle (plus Redis, Docker, and legacy integrations), with compliance-aware delivery—supported by AWS and CI/CD practices, and shaped by customer discovery, roadmap ownership, and mentoring.
