What I'm looking for

I’m looking to lead and build reliable backend systems as a Senior Python Engineer/Tech Lead/Engineering Manager in HealthTech, FinTech, or enterprise SaaS—combining deep Python architecture with team leadership, Agile delivery, and performance-focused engineering.

I’m a results-driven Senior Python engineer and people leader with 15+ years designing and delivering backend systems in high-stakes domains—US healthcare payer workflows and UK financial lending platforms.

At Zeomega, I led backend engineering teams through complex architectural refactors, improving platform reliability and significantly reducing production incidents. I architect and build REST APIs that handle millions of clinical and financial transactions while keeping data secure and HIPAA-compliant.

I enjoy bridging hands-on technical depth with leadership—mentoring engineers, driving Agile/Scrum delivery, and turning performance and reliability investigations into lasting fixes. I’m now seeking a Senior Python Engineer, Tech Lead, or Engineering Manager role in HealthTech, FinTech, or enterprise SaaS.
