Currently building: Smart Money DeFi Tracker Bot

builds working software,
not demos.

Software engineering student at Zetech University, Kenya. I ship Telegram bots, DeFi tooling, and full-stack platforms — then stay until the edge cases, geo-blocks, and session leaks are actually fixed.

// about

From class projects to production bots

I'm a software engineering student who learns by deploying — most of what I know came from debugging a live Telegram bot at 1am, not a lecture slide. My work spans three areas: automation tools that remove repetitive manual work, blockchain/DeFi tooling that talks to real chains and exchanges, and full-stack platforms that connect people to services.

I work incrementally and precisely — one file, one error log, one confirmed fix at a time. That habit comes from shipping bots that handle real money and real users, where a silent bug isn't acceptable.
