AI engineer and full‑stack developer building scalable web and voice‑driven AI systems.
ZimbabweWhat I'm looking for
I am an AI engineer and full‑stack professional with nine years’ experience delivering high‑scale web applications and AI‑driven products. I specialize in backend architecture, LLM orchestration, agentic workflows, and real‑time voice AI systems.
As Founder and Full Stack Engineer at AI Lab, I built a voice‑driven AI coach with a real‑time STT → LLM → TTS pipeline, agentic workflows, RAG integration, and analytics for monitoring and A/B testing.
In technical co‑founder roles I architected a payment platform for cross‑border UPI transactions and developed OCR + NLP and LLM‑powered semantic search systems for AI hiring, focusing on secure, high‑volume transactions and improved candidate‑job matching.
I develop end‑to‑end systems solo and in small teams—Python backends (AWS, Gunicorn, PostgreSQL, Nginx), SvelteKit/React frontends, multi‑process scaling, rate limiting, and database optimization—always prioritizing low latency, reliability, and measurable product outcomes.
