About this gig

I work with PostgreSQL every day as an SQL and backend developer, and I build Python backends on top of it with Django, Django REST Framework or FastAPI.


PostgreSQL work: slow queries found with EXPLAIN ANALYZE and fixed with the right indexes or a rewrite, schema design for a new project, views, functions and SQL reports, migrations and data cleanup.


Recent example: SmartStock, a multi-tenant inventory SaaS. I designed the PostgreSQL database and built the full backend: isolated company data, warehouses, stock transactions, roles, JWT auth, analytics, Excel export and a Telegram bot on the same database.


Bug fixes too: 500 errors, broken endpoints, failed migrations or slow pages in an existing Django or FastAPI project. I find the cause, fix it and explain what was wrong.


What you get:

A clear database design and REST API

Authentication, roles and permissions

API documentation for your frontend or mobile developer

Docker setup and deployment to your server


Please message me before ordering so we can agree on the scope. I test every query and endpoint myself before delivery.
