Python Django/FastAPI Backend Developer | SaaS APIs & AI

🎁 A 100% refund if I set the wrong expectation and can’t deliver. I’m a Python Backend Developer specializing in Django, FastAPI, REST API development, API integrations, and scalable backend systems. I help startups, SaaS companies, and growing businesses build secure, reliable, and production-ready backend applications that support real users and business operations. My focus is not just writing API endpoints. I design the complete backend structure, including database models, authentication, permissions, business logic, integrations, testing, documentation, and deployment. My Technical Skillset Backend: Python, Django, Django Rest Framework Frontend: React.js, Bootstrap Scraping & Automation: BeautifulSoup, Selenium Database: PostgreSQL, MySQL, SQLite DevOps: Docker, Heroku, Bash/Shell Scripting Cloud Technologies: AWS, Google Cloud, DigitalOcean Version Control: Git, GitHub, GitLab, Bitbucket What I Can Help You Build ✅ Python backend applications using Django, FastAPI, and Django REST Framework ✅ Secure and scalable REST APIs for web and mobile applications ✅ Third-party API integrations and webhook processing ✅ Authentication, authorization, JWT, OAuth, and role-based access ✅ PostgreSQL database design, migrations, and query optimization ✅ SaaS backend systems with subscriptions, user roles, and payments ✅ Background jobs and asynchronous processing using Celery and Redis ✅ API validation, pagination, filtering, logging, and error handling ✅ Existing backend debugging, refactoring, and performance improvements ✅ Swagger and OpenAPI documentation ✅ Unit testing and integration testing ✅ Docker-based development and cloud deployment 👉 PYTHON DJANGO SERVICES: ✅ Django Web Development & Django REST API Development ✅ Python Django Full-Stack Solutions with React/Vue.js integration ✅ Django Backend Development with PostgreSQL, MySQL, MongoDB databases ✅ Python Automation, Web Scraping, and Django Migration Services ✅ Django REST Framework for mobile and web APIs ✅ AWS Deployment for Django applications and Python projects ✅ Django Custom Application Development & API Integration 👉 FRAMEWORKS & TECHNOLOGIES: ✅ Backend: Django, Django REST Framework, Flask, FastAPI (Python) ✅ Databases: PostgreSQL, MySQL, SQLite, MongoDB, AWS DynamoDB ✅ Frontend Integration: React, JavaScript, jQuery, HTML5, CSS3, Tailwind, Bootstrap ✅ Cloud Services: Amazon Web Services (AWS), Digital Ocean, Heroku, Firebase ✅ DevOps & Tools: Docker, Redis, Nginx Server, Git, GitHub, Bitbucket ✅ Other Python Skills: Selenium, WebSocket, Bash Scripts, Celery, Scrapy, Pandas, NumPy Core Technologies Backend:** Python, Django, Django REST Framework, FastAPI, Flask Databases:** PostgreSQL, MySQL, SQLite, MongoDB APIs:** REST APIs, third-party API integration, webhooks, Swagger, OpenAPI Security:** JWT authentication, OAuth, role-based authorization Background Processing:** Celery, Redis, scheduled jobs Cloud and DevOps:** Docker, AWS, Microsoft Azure, GitHub Actions, CI/CD Frontend Integration:** React, Next.js, JavaScript, TypeScript - Django REST APIs: authentication (JWT, OAuth2, RBAC), serializers, admin panels, background tasks with Celery - FastAPI: async endpoints, Pydantic validation, OpenAPI docs, high-performance microservices - AI/LLM integration: Google Gemini, OpenAI API, LangChain, RAG pipelines, AI assistant backends, prompt engineering - Real-time features: Django Channels, WebSockets, Redis channel layer, event-driven systems - Database: PostgreSQL, MySQL, schema design, query optimisation, indexing - Infrastructure: Docker, Redis, AWS (EC2, S3, RDS), CI/CD pipelines How I Work I first understand your business workflow, users, existing system, and technical challenges. I then prepare a practical implementation plan before starting development. My priorities are: • Clean and maintainable Python code • Secure and well-structured APIs • Scalable backend architecture • Clear communication and regular updates • Proper testing and technical documentation • Reliable delivery without temporary fixes I am comfortable joining a project at any stage, whether you need to build a backend from scratch, add new Django or FastAPI endpoints, integrate an external service, fix an unstable API, improve PostgreSQL performance, or modernize an existing Python application.
