I will build a rest API backend with database


About this gig
A REST API that still makes sense six months from now, from a software architect with 12 years of professional experience.
I build backends in Python (FastAPI, SQLAlchemy) and PHP 8, with the database designed on purpose instead of grown by accident. Live examples: a multi-tenant SaaS with subscription plans and background workers, membership automation over Patreon and Twitch OAuth, and real-time platforms over WebSockets.
WHAT YOU GET
- REST endpoints with validation and proper error handling
- Relational schema design and migrations
- Authentication: JWT, OAuth 2.0 or API keys
- Webhooks, background jobs, queues and caching
- Integrations with anything that has an API: payments, Discord, Telegram, Twitch
- Interactive API docs, so your frontend developer never has to ask you
- Deployment on your server, Windows or Linux
Unlimited revisions until it does what you asked. Full source code and documentation, always.
Not sure which package fits? Message me with your endpoints and I will tell you, or send you a custom offer.

FAQ
Can you work with my existing database?
Yes. Send me the schema and I will build on it, and tell you if something in it will cause you trouble later.
Do you write documentation?
Interactive API docs come with every package, so your frontend developer can work without asking you anything.
Python or PHP?
Both. If you have no preference, tell me what the API is for and I will recommend one and explain why.
Will my frontend developer be able to use it?
That is the point. Standard REST, predictable errors, and docs they can click through.
Can you also deploy it?
Yes, Windows Server with IIS or Linux, included in Premium and available as an extra on the others.
