Languages

TypeScript and JavaScript across the web stack, Python for data analysis, Java and Groovy for production backend services, and Bash for tooling and automation.

Frontend

React for the customer-facing web app — including ownership of accessibility and end-to-end testing with Playwright.

Infrastructure

AWS is the primary cloud, with GCP also in use. I own services end to end — from Docker image to production — running on Kubernetes managed by our platform team.

Data

Owning schema design and migrations for PostgreSQL across the services I build. Redis and Kafka are consumed from layers that other teams own.

Product

Owning product metrics and experimentation in Amplitude, and triaging production issues through Sentry.
