## About

```text
At Irembo, I designed and implemented an LLM chatbot using vector embeddings, and developed web applications with Java backend services and Angular. I also contributed to the MSD project to deliver 100 services within 6 months.

At Pomme-Health, I architected and built the backend system, including scalable RESTful APIs and database schemas. I also led backend–frontend integration and managed deployment and CI/CD pipelines.

At Carnegie Mellon University - Africa, I built J.A.M.B.O., an AI-powered English and French WhatsApp support agent for JA Africa using RAG over curated knowledge bases. I led bilingual testing and evaluation and authored client-facing technical documentation.
