About this gig

I build the backend so your app, dashboard, or SaaS product actually works: fast, secure, ready for real users.


Proof: I built a FastAPI + PostgreSQL system spanning 240+ tables and 25 schemas, holding sub-100ms response times under a 117-role permission system, plus a real-time platform serving 10,000+ live users at 99.9% uptime, with a dedicated async scheduler syncing live data every 5 minutes without blocking requests.


What I build:

FastAPI REST API development

PostgreSQL database design and integration

JWT authentication and authorization

Role-based access control (RBAC)

Async CRUD endpoints

Real-time data delivery (WebSocket / polling, sub-100ms)

Swagger / OpenAPI documentation

Redis caching and rate limiting

Input validation and error handling

Database migrations

Deployment assistance


Fits SaaS apps, internal tools, dashboards, mobile backends, and ERP-style systems.


Message me what your app needs to do before ordering, and I will outline the exact structure I would build, free.

I design and build the databases and backends behind data-heavy products. PostgreSQL/MySQL architecture, multi-tenant SaaS with database-level tenant isolation, FastAPI backends with JWT/RBAC security, and ETL pipelines processing 2+ billion rows. Recent work: a 240+ table university ERP API across 3 databases and 25 schemas with a 117-role RBAC system, and a real-time FastAPI platform serving 10,000+ users at sub-100ms latency. Tell me your data or backend problem and I will tell you exactly how I would solve it.
