Writing about analytics, experimentation, and lessons from building data-driven products.

Coming Soon

I'm working on writing up my learnings from building ML models, running experiments, and finding cost leakage in operational data. Check back soon!

Topics I'm planning to write about:

ML Coming Soon

Why our ML recommendation model beat rule-based matching by 80%

The architecture, training data choices, and surprising lessons from A/B testing a recommendation engine at scale.

Experimentation Coming Soon

The anatomy of a good A/B test: lessons from 10+ experiments

What makes an experiment actually useful? Hypothesis quality, metric selection, and when to ship vs when to kill.

Cost Coming Soon

Finding S$457K in cost leakage nobody knew existed

How I audited the entire payout pipeline and found three separate cost leakage vectors that were invisible to the finance team.

Engineering Coming Soon

Building self-serve analytics: from data requests to data independence

The flat table architecture and internal tools that cut our team's analysis overhead by 40%.
