Tools I actually reach for

Frontend

React and Next.js for product surfaces, TypeScript everywhere, Vitest/Jest to keep regressions honest.

Backend

Started with Java, grew up on Node.js, and these days I lean on Go for performance-sensitive services. PostgreSQL for data, Redis for cache and queues.

Cloud & ops

AWS is home base, with detours into GCP. Docker for everything, Terraform when infra needs to live in code, Datadog and Sentry to know what's actually happening.

AI

Spending a lot of time on agent workflows lately — building copilots that plug into existing stacks instead of replacing them.
