I will develop python fastapi backend and django rest api
Hanzlah
About this gig
Need a fast, secure backend for your app or SaaS? I build high-concurrency, async architectures using FastAPI and Django. Clean, optimized Python code built for speed.
Tech Stack:
FastAPI, Django, DRF, AsyncIO
PostgreSQL, MySQL, Redis, Grafana
Docker, AWS S3, Nginx, Sentry
Services:
Basic: Up to 5 async endpoints, CRUD, DB setup. Ideal for webhooks/automation.
Standard: Up to 10 optimized endpoints, JWT/OAuth2 Auth, clean DB design.
Premium: Complex schemas, Redis caching, Celery queues, Docker, Swagger/ReDoc docs.
CRITICAL: This is a STRICTLY BACKEND GIG. No UI/Frontend (React/WordPress). In the pricing table, "Pages" translates directly to Core Data Models or Feature Modules.
Why Me? AsyncIO performance focus, clean architecture, and easy integration for frontend developers.
MESSAGE ME BEFORE ORDERING to discuss your database architecture and project scope!

Hi, I'm Hanzlah, a Software Engineer specializing in Python backend development, web automation, and data engineering. I help businesses eliminate manual workflows, build high-performance REST APIs, and engineer secure, scalable data systems.
What I do:
→ Web Scraping & Automation (Playwright, Selenium)
→ Custom Backend & APIs (FastAPI, Django)
→ ETL & Data Processing (Pandas, SQL, MongoDB)
→ AI & LLM Pipeline Integration (OpenAI)
I focus on delivering clean, containerized, and production-ready code. Let's discuss your project requirements!
FAQ
Do you use FastAPI or Django for the python backend?
It depends entirely on your system requirements. I use FastAPI paired with AsyncIO when your system requires high-concurrency, low-latency microservices and rapid data processing. I utilize Django when your project needs a mature, robust framework with built-in admin panels, powerful ORM powers.
Will my REST API come with integration documentation?
Yes. Every python backend and REST API I build via FastAPI automatically includes interactive Swagger UI and ReDoc documentation. For Django projects, I implement Django Rest Framework with Spectacular/Swagger to ensure your frontend or mobile teams have immediate and clear documentation.
Do you containerize the backend application using Docker?
Yes. For production-ready environments, I configure Docker files and docker-compose configurations. This ensures your FastAPI backend, Django API, and databases (like PostgreSQL) deploy consistently across any cloud infrastructure without dependency conflicts.
Do you design the frontend, user interface (UI), or visual website?
No. This is a strictly backend engineering gig. I do not create user interfaces, HTML/CSS, React components, or WordPress layouts. I build the underlying engine—the databases, APIs, server logic, and security systems—that powers your mobile app or frontend website.
FastAPI vs. Django—which framework should I choose for my project?
If you aren't sure, message me and I will recommend the best fit for your project.
Do you handle deployment, server setup, and hosting?
Cloud or VPS deployment (Docker, Nginx, AWS S3, Linux setup) is fully included in the Premium Tier. For the Basic and Standard tiers, I deliver a clean, locally running codebase with installation guides, but you can easily add production deployment as a Gig Extra.
What do you need from me to start working on my project?
1. An API specification or endpoint list. 2. Frontend wireframes, user flow diagrams, or database schema concepts. 3. Any 3rd-party service requirements (Stripe, Twilio, SendGrid, etc.).
Can you optimize an existing Python backend that is slow?
Yes! I can review your existing codebase to implement asynchronous optimizations, clean up database queries (eliminating N+1 query problems), set up Redis caching, and improve response times. Please message me first with your current codebase repository to discuss a custom offer.
