I architect frontend platforms that scale across teams

6+ years building frontend platform infrastructure. Module Federation for decoupled deployments, service discovery on Kubernetes, and shared libraries that give teams a consistent foundation without tight coupling. I focus on the architecture that lets product teams ship fast and independently.

What I focus on

Microfrontend Architecture
Designing module boundaries, runtime integration layers, and automated service discovery on Kubernetes that dynamically registers modules per customer instance. Battle-tested Module Federation powering real customer deployments.
Frontend Platform Engineering
Building the UI shell, shared libraries, and developer tooling that let 6+ product teams deploy independently without coordination overhead. Consistent patterns and guardrails so teams can focus on shipping product.
Scaling Teams & Architecture
Leading multidisciplinary engineering teams through architecture decisions, technical discovery, and the solution design that frontend-at-scale demands. From hiring and onboarding to setting technical direction across teams.
