Polyglot by habit, what I reach for depends on the problem.
APIs, data flows, and the boring-reliable plumbing.
Relational by default. Strong preference for raw SQL, ORMs are fine when they fit.
Components, state, and the CSS in between.
Google cloud, or running the server myself when needed.
Unit, integration, E2E — whatever the layer demands.

Disk-backed key/value cache for go. Atomic writes via tmpfile + rename, per-key file locks for concurrent access, symlink-based TTL expiration.
github →CLI that generates typescript types from openapi schemas (yaml or json). Written in go, ships as a single cross-platform binary.
github →Client-side SHA-256 for multi-gigabyte files. Streams data through web workers and hash-wasm to sidestep web crypto's full-file memory limit.
github →Backend interview take-home. Go + postgres api with a vue frontend, role-based access, openapi-validated, dockerized end-to-end.
github →# These are independent projects. Many more on github.
# For a full overview of professional work, request an interview.
