A UK company gave me a freelance project. They liked the work, gave me another, then hired me as their Senior AI Engineer. That was a year and a half ago. I'm still there. One pipeline I built for them cut a 3–4 day process down to 5 minutes — now running for 5,000+ users. That’s the level of impact I focus on. What my client say about me: ✅ "Not just executing but thinking along the line with me" ✅ "Exceeded our expectations" I build Python backends where AI is doing actual work inside your product — not just a demo, not a chatbox bolted on the side. OpenAI, Claude, Gemini — I've worked across all of them, using frameworks or native SDKs depending on what fits. FastAPI, Flask, Django — whichever makes sense. I also handle Docker, CI/CD, and deployment, so you end up with something live and running — not code that only works on my machine. — We're probably a great fit if you're thinking: ⚡ "I have an idea but I don't know how to make it real" ⚡ "My prototype works — now I need it to handle actual users" ⚡ "I don't want to pay someone to build something I'll need to rebuild in 6 months" ⚡ "I want someone who communicates clearly — not someone who disappears and sends code" ⚡ "I need AI that actually works — not another demo" — Probably not a fit if: ✗ You're looking for the cheapest option — good production AI has a real cost ✗ You want someone who executes without question — I'll always say if I see a better way ✗ You need a quick prototype with no plans to maintain it ✗ You're still figuring out if you want to build — come back when you're ready — I only take on work I know I can deliver properly. If something's outside what I do well, I'll tell you upfront — before we start, not halfway through. If you're building something serious with Python and AI at the core, let's talk. — Python · FastAPI · Flask · Django · OpenAI · Claude · Gemini · Agno · Docker · PostgreSQL · Redis

Most backends are functional. The ones I build are production-ready, maintainable, and ready to integrate AI when your product needs it. I'm Andrew, a Python backend developer specialising in Django REST Framework and FastAPI. 16 contracts delivered on Upwork, every reviewed client gave 5 stars. Two production systems showcase the range: - Diba Fintech API (Django REST Framework, live in production). Lead engineer Alerechi Ordu: "a great asset to the team, consistently delivering high-quality work with strong attention to detail." - Doctor AI (Django 5 + Google Gemini API) — a health analysis platform with 23 custom system prompts across diagnostic categories. Live demo: andrewoduola.online/projects/doctor-ai Core services: - 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 this works in practice: The first conversation isn't about the spec, it's about what you're actually building and why. You get a clear plan with trade-offs flagged before any code is written, regular check-ins so nothing drifts, and clean, tested, documented code as the baseline. Disappearing mid-project isn't a thing that happens. Every reviewed client on Upwork has mentioned communication specifically, not as a side comment, but as a standout. If your backend needs to be production-ready, not just functional, there are two ways to start: - Send your spec, and you'll get a written technical plan back within 4 hours, or - Book a 15-minute call, and we'll walk through your stack and constraints together. Whichever fits your week. - Andrew (Drew), Lagos. Available now, working across US, EU, and APAC time zones.

7+ Years of Experience | Top Rated Plus Most businesses don't struggle because of a lack of ideas—they struggle because their systems can't keep up.
