What I'm looking for

I seek a technical leadership role building compliant, scalable backend systems in fintech or healthcare, with strong engineering practices and cross-functional collaboration.

I am a lead back-end engineer with deep experience designing and delivering scalable, secure backend systems for fintech and healthcare platforms.

At PowerPay I oversaw back-end architecture for a financial platform, drove legacy modernization, and implemented features to streamline NACHA processes and HubSpot integration for rapid internal data visualization.

Previously at Vessel Partners I led API and backend development for HIPAA-compliant healthcare applications, instituted CI/CD and code-quality practices, and partnered with university researchers on a social-needs app to deliver resources to users.

At CashWay I migrated monolithic systems to microservices, built secure payment and account-management APIs, and led cross-functional teams to deliver mobile banking MVPs, focusing on reliability, compliance, and user-centered features.
