$ whoami → problem solver, AI + DevOps background

Jehoiada Wong

I like building solutions to real problems. I just happen to have a deep background in AI and DevOps, so they tend to come out automated, smart, and built to stay up.

Finance first, then infra

I made my first stock trade at 15, back when making money was the whole point. Then a mentor on the technology side of investment banking introduced me to algorithmic trading, and I wanted to know how firms build the infrastructure and strategy that give them an edge. That pulled me into DevOps engineering for trading infrastructure and AI-driven algorithmic trading.

These days I just like building solutions to real problems. A deep background in DevOps and AI is the toolkit: infrastructure that stays up, and intelligence wired in where it actually helps.
