I've built production AI systems for SimplifiedIQ, Zummit Africa, Cogrea, and Theyas Inc., spanning multimodal grading, legal research, real-time voice AI, recruiting, and education. My work includes Examurai, a grading platform with async OCR, ARQ orchestration, webhook delivery, rubric generation, and Redis idempotency controls.

At SimplifiedIQ, I rebuilt a question-generation engine to run 5x faster at 30x lower cost, built a 12-stage plagiarism and authorship pipeline, and developed AI course generation and educator-development tools. At Zummit Africa, I built RAG support systems that cut response time by 65% and human workload by 70%, alongside CV matching, recommendation, forecasting, and live computer-vision products.

I work across the full ML lifecycle: designing RAG and multi-agent workflows, deploying FastAPI services, managing retrieval and session infrastructure, and improving reliability after launch. I care about making complex AI systems safe, measurable, and dependable under load.
