About this gig
Production-ready Python APIs, built and deployed. I specialize in FastAPI backends that are clean, fast, and secure from first endpoint to live traffic.
What you get:
- RESTful API with clean endpoint design
- Authentication (JWT, OAuth2, API keys)
- Database integration (PostgreSQL, SQLite, Redis)
- Input validation, error handling, and logging
- Auto-generated Swagger/OpenAPI docs
- Deployment guide (Docker, Nginx, Linux)
Why me: I'm the founder of Fallen Angel Systems, where I built a real-time AI security API processing thousands of requests with sub-100ms response times. Live in production, real customers, real traffic. I built every layer ML inference to Nginx deployment. This isn't tutorial-level work. I build APIs that ship. Perfect for:
- Startups needing an MVP backend fast
- Teams adding endpoints to an existing app
- Projects needing auth, database, and deployment done right
- Migrating from Flask to FastAPI
Also experienced with: Flask, Django, SQLModel, Pydantic v2, WebSockets. Every project includes source code, docs, and a deployment guide. Message me with your project details I'll reply within hours with a clear scope and timeline.

Founder of Fallen Angel Systems. I built Guardian (AI defense - prompt injection scanner) and Judgement (AI offense - red team attack console). Active bug bounty hunter with submissions to Microsoft MSRC and HackerOne.
I specialize in AI security, Python/FastAPI backends, ML pipelines, and Linux infrastructure. Published red team research on Claude, GPT-4o, and Sonnet model security.
I don't just run tools and hand you a report. I understand the attacks because I built the defenses.

FAQ
What do you need from me to get started?
A brief description of what your API needs to do, what data it handles, and any specific tech requirements (database preference, auth type, hosting). I'll ask clarifying questions if needed.
Do you deploy the API or just deliver code?
Both options available. I can deliver clean source code with a deployment guide, or I can deploy it to your server (VPS, Docker, cloud). Deployment is included in Standard and Premium packages.
Can you work with an existing codebase?
Absolutely. I can add endpoints, fix bugs, refactor, or extend an existing FastAPI, Flask, or Django project. Just share the repo and I'll scope it out.
How fast can you deliver?
Basic APIs (3-5 endpoints) in 3-5 days. Larger projects with auth, database, and deployment typically 7-10 days. Need it faster? I offer expedited delivery.
Do you provide documentation?
Every project includes auto-generated Swagger/OpenAPI docs, a README with setup instructions, and inline code comments. You'll be able to understand and maintain the code after delivery.
