About this gig
Need a clean, scalable backend for your app, MVP, dashboard, automation tool, or AI product?
I will build a custom FastAPI REST API with a database backend, clean project structure, request validation, documentation, and optional advanced features such as authentication, WebSockets, frontend integration, Docker, deployment support, and custom AI integration.
I specialize in Python backend systems that are easy to understand, extend, and deploy.
What I can build
- FastAPI REST APIs
- PostgreSQL, SQLite, or MySQL database backends
- SQLAlchemy / SQLModel models
- Alembic database migrations
- CRUD endpoints
- Authentication and user roles
- Admin or user-facing API workflows
- WebSocket features for real-time updates
- React, Next.js, or basic frontend integration
- Docker / Docker Compose setup
- Third-party API integrations
- Custom AI integration using OpenAI, local LLMs, Ollama, Hugging Face, vector databases, or RAG pipelines
- Internal tools, MVPs, SaaS backends, automation APIs, and data-driven apps

FAQ
Can you build the frontend too?
Yes. I can build a simple dynamic frontend, admin dashboard, or API-connected interface. More complex frontend work should be quoted separately.
Can you add AI integration?
Yes. I can integrate AI features such as chatbots, document Q&A, RAG pipelines, local LLMs, OpenAI-compatible APIs, Ollama, Hugging Face models, or custom model endpoints.
Can you use my existing database?
Yes, as long as you can provide the schema, sample data, or connection details. For security, use test credentials or temporary credentials.
Do you provide deployment?
Deployment is available as an extra. I can prepare Docker, Docker Compose, Nginx, Cloudflare Tunnel, VPS deployment, or cloud deployment guidance.
Do you provide source code?
Yes. All packages include source code unless we agree otherwise.
Can you work on an existing FastAPI project?
Yes. Please send the repository structure, current issue, and what you want added or fixed.
Which database should I use?
For most production apps, I recommend PostgreSQL. For small prototypes or local tools, SQLite can be enough.
Do you build WebSocket APIs?
Yes. I can add real-time updates, notifications, streaming responses, live dashboards, or chat-style features using FastAPI WebSockets.
Do you write tests?
Basic tests can be included in Standard or Premium packages. More complete test coverage can be added as an extra.
What do you need from me to start?
I need your app idea, required features, database entities, endpoints, authentication needs, deployment target, and any frontend or AI requirements.
