About

Senior AI engineer for software people can trust.

I build AI tools, backend platforms, and workplace software with clear evidence, careful controls, and human oversight.

02_Professional summary

I am a Senior AI Engineer with eight years of software engineering experience across AI, backend platforms, distributed systems, and applied machine learning. I graduated in Software Engineering from the Harare Institute of Technology.

Since 2018, I have led engineering teams, built founder-led products, and scaled an AI platform at Africai past 20,000 active users as CTO. Contract work with teams in the UK and US has kept the stack honest across backend, frontend, Web3, and IoT.

Today I work independently on LangGraph/LangChain AI workflows and RAG services with FastAPI on AWS. I focus on clear limits, useful records, and software that is ready for real users.
