Hi, I’m Yudhiesh.

I’m Lead Data Scientist at OneCredit, based in Kuala Lumpur. I work on machine learning and the engineering needed to make it useful in practice.

Before OneCredit, I worked on ML infrastructure for quant trading at Trontal Group and built ML platforms at MoneyLion, helping data scientists get their models into production.

This blog is my engineering notebook. I write about questions I run into, experiments I try, and the trade-offs that show up once a system has real users. Lately, that’s meant vector search, LLM safeguards, and the data behind them.

A little teaching, too

I’ve taught more than 1,500 engineers through courses at Uplimit:

Teaching is a useful test of whether I understand something well enough to explain it. Writing here serves much the same purpose.

Say hello
