What I'm looking for

I want to keep owning features end-to-end on teams where I can collaborate across product and leadership, handle reliability and integration-heavy work, and mentor engineers while planning roadmap execution.

I’m a senior full-stack engineer focused on integration-heavy, realtime features and end-to-end ownership—from scoping through deployment and whatever breaks after.

At my latest role (Responsive, Apr 2023–Present), I led performance and architecture work that cut response times on the lowest endpoints by more than half using service decomposition and targeted infrastructure changes.

I’ve also shipped customer-facing APIs/services for content library workflows, modernized authentication (JWT/refresh token rotation and SSO), and delivered frontend replacements for legacy screens (Jan 2021–Mar 2023).

Earlier, at Maritz (Jan 2019–May 2021), I built full-stack redemption and event registration features, modernized frontend performance, and added automated regression test suites ahead of high-traffic registration events.
