What I'm looking for

I'm looking for opportunities to build and deploy practical AI and NLP products, combining machine learning, MLOps, and full-stack engineering in remote or relocation-friendly teams.

I led the development of bantu.info’s multilingual sentiment analysis and retrieval platform, training and deploying NLP models for Shona, Ndebele, and English. I built its ingestion pipelines, FAISS semantic search, RAG capabilities, and Dockerised FastAPI service on Google Cloud Run.

At Visyn Technologies, I lead architecture and delivery across four products, building full-stack systems and shared API and data standards. I bring production experience across Python, JavaScript, PHP, cloud deployment, CI/CD, testing, and technical mentoring.
