Capabilities

The parts I’m good at.

Most of my work sits between layers: where an event becomes state, state becomes an interface, and failure has to become a product decision.

Real-time systems

Designing event-driven flows that carry reliable state from background processing to responsive web interfaces.

Azure Functions · Cosmos DB · Web PubSub · Next.js

Quality engineering

Building production-like automated testing around the workflows most likely to fail at system boundaries.

Playwright · Vitest · Testcontainers · CI/CD

Resilient product UX

Making loading, offline, validation, and transient-failure states deliberate parts of the product experience.

React · TypeScript · Service workers · Accessibility

Typed integration

Keeping browser, API, queue, and persistence contracts explicit so changes remain understandable and recoverable.

TypeScript · Zod · OpenAPI · C#/.NET

Experience

Six years, three product teams.
