What I'm looking for

I seek a leadership role where I can grow engineering teams, drive product impact, mentor engineers, and improve operational reliability in a collaborative, product-focused culture.

I am an Engineering Manager with 15+ years in product development and over five years leading high-performing teams on consumer-facing platforms. I focus on scaling teams, improving developer productivity, and delivering reliable systems.

At Amazon I led an organization of 20 engineers owning ~15 customer-review platforms, reduced on-call incidents by ~40%, and promoted five engineers while balancing long-term roadmaps, technical debt, and team sustainability.

My background includes senior software engineering, tech lead and cofounder roles across startups and scale-ups where I built frontend architectures, full-stack systems (including Ruby on Rails), and led small teams to improve funnels and customer experience.

I prioritize people development, operational excellence, and product impact, partnering closely with Product and UX to deliver customer-facing improvements while reducing technical surface area.
