I build Python backends with security handled properly — authentication, access control, and data protection built in from the start, not added later. Authentication & Security — JWT and OAuth authentication, role-based access control (RBAC), and permission layers. Multi-tenant data isolation so one client's data never reaches another. Secure API patterns and abuse prevention. Security treated as a baseline, not an afterthought. Backend APIs — FastAPI, Django, and Flask. REST APIs designed to be versioned and extended safely. Async processing, background jobs, and webhook workflows. Clean structure with clear boundaries. Database & Deployment — PostgreSQL schema design, Redis caching, Docker, AWS, and CI/CD. Backends built to run reliably in production. Beyond the API — When a project needs the frontend handled, I build the server-rendered side of Django/Flask: templates (Jinja / Django templates) with the HTML, CSS and JavaScript around them, so you get a complete app rather than just endpoints. AI integration — I've built LLM and RAG features into backends, wired securely to your data and APIs. It's not my main focus, but when a project calls for it, I build it in properly. I'm a good fit when: - You're building something with authentication, permissions, or sensitive data - You need multi-tenant systems with proper data isolation - You want security handled correctly, not bolted on at the end - You need a reliable backend that's built to last Tech: Python, FastAPI, Django, Flask, PostgreSQL, Redis, JWT, OAuth, Docker, AWS, JavaScript
