Message

At Tangazoletu Limited, I take Credit Pro services from design through production rollout and monitoring. I wrote a SQL parser and evaluator that serves cached reads with Oracle-equivalent results, reducing the same query from 1.9 seconds to 0.5 seconds.

I also replaced an n8n onboarding workflow with a C service, bringing processing time from about 90 seconds to 2–4 seconds on roughly 1.2 million cells. At Blink Electrics, I shipped a real-time IoT CO2 monitoring platform and built ginnery monitoring across 43 sites for Tanzania Cotton Board.
