United StatesWhat I'm looking for
I am a senior full-stack engineer with 8+ years building large-scale, revenue-critical ads, fintech, and productivity platforms using React/Next.js, TypeScript, Node.js, Go, C#/.NET, and Python. I focus on shipping resilient features that boost engagement and conversion while aligning engineering, product, and data science on measurable outcomes.

I emphasize observability, test-driven development, accessibility (WCAG), and platform resiliency using Docker, Kubernetes, AWS, Terraform, and CI/CD practices. I enjoy mentoring peers, collaborating cross-functionally on compliance and risk, and delivering production systems for millions of users.
