Andrew O — Backend Development freelancer in Akure

Django and FastAPI backends that are production-ready, scalable, and built for AI integration — for startups and SaaS teams that need it done right the first time. I'm Andrew (Drew), a Python backend developer working with startups and established products on Upwork. Top Rated with a 100% Job Success Score across every completed contract. Every client who's left a review has mentioned communication specifically, not as an afterthought, but as a standout. Right now I'm working on two production systems simultaneously: a fintech API for Diba (Django REST Framework, live in production) and an NGO platform where I'm integrating OpenAI to deliver a personal AI assistant to end users. The lead backend engineer at Diba described my work as "consistently delivering high-quality work with strong attention to detail." What I build: — REST APIs with Django REST Framework: JWT\u002FOAuth2 auth, RBAC, serializers, pagination, admin systems, Celery background tasks — FastAPI services: async endpoints, Pydantic models, full OpenAPI documentation — AI\u002FLLM integration: OpenAI API, LangChain, RAG pipelines, conversational assistant backends, AI-powered automation — Real-time systems: WebSockets via Django Channels, Redis channel layers, live event-driven UIs — Database design: PostgreSQL, MySQL, query optimisation, indexing, migrations — Infrastructure: Docker, Redis caching, AWS (EC2, S3, RDS), CI\u002FCD pipelines How I work: I start by understanding what you're actually building and why — not just the spec. I flag problems early, explain technical decisions in plain language, and don't disappear mid-project. Clean, tested, documented code is the baseline, not the goal. If your backend needs to be production-ready — not just functional — send a message or invite me. I'll respond within 4 hours and I'd like to hear what you're working on.
