Django Backend Developer | Python, DRF, FastAPI, PostgreSQL APIs

Django and Python backend developer building secure, scalable REST APIs and full production systems. If your backend needs clean APIs, a solid PostgreSQL schema, and an architecture that holds up under real load, I ship it end to end. With 5+ years in backend and full-stack development, I turn requirements into maintainable, tested, deployed systems, not prototypes. I work in Python, Django, Django REST Framework, and FastAPI, and I design for scale from day one. WHAT I BUILD Backend and API development - REST API design with authentication, permissions, and versioning - Django, Django REST Framework, and FastAPI services - Clean, modular, well tested code from the first commit - Query and performance optimization, caching, and load handling Databases and data engineering - PostgreSQL and MySQL, schema design, migrations, complex filtering - ETL and multi source data pipelines - Background and scheduled jobs with Celery and Redis - Web scraping and third party API integration Full stack and SaaS platforms - End to end SaaS from database schema to deployment - Multi tenant apps, admin dashboards, reporting backends - Auth, roles, billing, and user management - Dockerized deployments built for long term growth AI integration (when your product needs it) - Claude, OpenAI, and LLM integration with structured, reliable outputs - Automated scoring, reporting, and processing pipelines built into real products RECENT WORK - Built a business risk scoring platform: custom scoring engine, automated data aggregation, and AI generated narrative reports that replaced a fully manual process. - Engineered a Django, Celery, and PostgreSQL backend handling real time and scheduled processing at scale. - Developed multi source pipelines pulling state records, licensing platforms, and external APIs into one unified verification platform. HOW I WORK Clear communication, replies within a few business hours, and delivery you do not have to babysit. You get documented, tested, production ready code and an architecture built to grow. If you need a backend that will not fall over as you scale, send me a message with a short description of your project and I will reply with how I would approach it.
