● Available for new work
Let'sbuildsomething.
I'm a backend engineer who ships clean, boring, well-tested APIs. If you have an idea that needs a real backend — or an existing one that needs love — I'd like to hear about it.
What I can do for you
Four flavors of work. If yours doesn't fit, message me anyway.
REST API design & build
FastAPI services from zero — auth, validation, OpenAPI docs, tests, and clean migrations.
Backend for your product
Database modeling, business logic, integrations (Stripe, email, storage), and deploy pipeline.
Performance & cleanup
Audit slow endpoints, fix N+1 queries, add caching, tighten schemas, write the missing tests.
Technical sparring
Hourly calls to review architecture, debug a gnarly bug, or pair on a tricky migration.
