Three full-stack projects

Backend-focused full-stack developer building products that actually ship.

I build the server side — typed APIs, layered architecture, auth, migrations and payment flows — and take products all the way to a deployed, running site. Below are three that are live right now.

Selected work

Each project is deployed and running — the cards link straight to the live sites.

The backend decisions I don't skip

The interesting work lives on the server. Across these three projects, a few production-minded choices show up every time.

01

Correctness around money

Prices stored in cents, idempotent payment endpoints keyed by an idempotency_key, and typed Pydantic v2 boundaries — financial flows that don't drift or double-charge.

02

Security by default

JWT + bcrypt auth, per-endpoint rate limiting to resist brute-forcing, and file downloads resolved from the database — closing path-traversal holes instead of trusting the URL.

03

Built to run

Layered routes → services → models, Alembic migrations, Docker and GitHub Actions CI, and pytest suites — so each service deploys cleanly and stays alive in production.

Available for work

Have a product that needs building end to end?

I take projects from the first API route to a deployed, running site. Let's talk about yours.
