Hire Me
I’m a staff engineer with 15+ years of experience helping teams turn product goals into reliable systems, scalable platforms, and measurable business outcomes.
My background spans mobile, backend, platform quality, observability, and AI-enabled workflows. I’m most effective in roles that combine hands-on technical depth with architecture leadership, cross-team influence, and a strong focus on delivery quality.
In my latest role, I’ve led work that increased support automation to 75%, saved $10M+ annually, and strengthened mobile observability and release quality for a product with 60 million monthly active users. I care about building systems that create real customer value and helping teams adopt better tools and practices in pragmatic ways.
