CTO at Shamiri in Nairobi, Kenya. I lead a team of 4 engineers building AI and health tech for youth mental health care.
- shamiriAI: LLM evaluation that scores therapy session fidelity and flags safety concerns in code-switched English, Swahili and Sheng.
- whisper-shamiri-200: Whisper Small fine-tuned on Swahili and English code-switched therapy audio.
- Shamiri Digital Hub: Next.js and PostgreSQL. I migrated it from Prisma to Drizzle and built a k6, Playwright and Lighthouse load-test setup. In load tests, median page load fell from 1.08 s to 63 ms and one server handled 5.4x more traffic.
Before Shamiri: Ilara Health (Head of Technology, Product Manager) and PayGo Energy (Software Engineer, OpenPAYGo token and LPG meter systems).
