I build production Python backends and LLM-powered document intelligence systems.

I've built Django e-commerce platforms at Odne Consulting and Naijazone Online, improving bookstore sales by 8% and delivering vendor inventory, ordering, analytics, and payment workflows.

At Turing, I generated 500+ code datasets and evaluated 1,000+ AI-generated outputs for RLHF workflows. I also produced SFT examples, red-teamed computer-using agents, and collaborated with ML engineers on reusable data-quality standards and evaluation frameworks.

My work spans FastAPI, Django, PostgreSQL, Docker, Kubernetes, AWS EKS, and CI/CD. In DocuChat-Py, I built an async RAG document chatbot with OpenAI embeddings, Celery, Redis, JWT authentication, Docker Compose, and local Ollama inference.

I've also trained more than 5,000 students in robotics and Python, creating hands-on learning materials and mentoring computational thinking.
