Growth Engineer

Taking fine-tuning to the next level

While I’ve shipped a lot of growth wins (literally the first line on my resume), I’m actually very far from a prototypical growth engineer. That said, in this piece, I want to explore a bit more into what it’s like being a growth engineer and what makes you good at being one. Growth engineers are generally 1 -> 100 experts instead of 0 -> 1. They fine-tune every little detail by running a lot of experiments with marginal changes to understand the user problem and drive growth impact (line goes up). ...

Product Growth Opportunities

Finding ideas that brings you from 1 -> 100

It’s never easy to come up with new ideas that help with growth, but identifying the problem makes it easier. You’ll notice that for the most part in this piece, I’ll talk about “where” the opportunities are instead of “what” because that’s usually very domain specific and highly depends on the type of problem you ended up needing to solve. This is part of a series (The Opinionated Engineer) where I share my strong opinions on engineering practices. ...

A/B Testing

Basic guide to running a good A/B test

This is a basic introduction on how to run a good A/B test. A/B testing is a method where your user pool is segmented into multiple groups, allowing you to test different product interactions and understand how these changes affect user behavior. For any metric / data driven team, A/B testing serves as a critical tool in measuring success. This is part of a series (The Opinionated Engineer) where I share my strong opinions on engineering practices. ...

No Blame SEV (Incident) Culture

Less finger-pointing, more preventions

Every time there’s a major outage at Meta, the first question I get from friends and family is usually “did they fire the person who caused it?” which is where I have to explain this concept of No Blame SEV Culture. Especially for an outage so big that a significant number of users are affected, the individual causing it likely does not have ill intent and there are likely multiple different processes and systems that failed along the way to get us here in the first place. ...

Code Review Culture

Review today or debug tomorrow

Ask a programmer to review 10 lines of code, he’ll find 10 issues. Ask him to do 500 lines and he’ll say it looks good. - @girayozil Code review is a really subjective thing where each team or even individual runs things very differently. However, a bad code review process can lead to bad code smells and unnecessary tech debt (just ask all the vibe coders out there 🫣). I will try my best to share my rather opinionated takes while explaining the reasoning behind each of them. ...

The Art of Posting

It's both self-promotion and communication

This piece is specifically more about Meta’s unique culture of “posting” about things but I imagine it can be a useful reference on communication in general. Many people loathe this process and complain about how it’s just a lot of “self-promotion” and while there’s definitely some truth to it, it’s also a valuable communication avenue that you can leverage to your advantage. As we will explore further below, posting by itself is more of a bonus as the post will still require actual substance (which is your work lol). ...

Push Fearlessly with Automated Testing

Move faster by moving slower

Conventional wisdom is that writing tests slows you down, because the alternative is that you don’t need to write tests. In fact, Meta (then Facebook) was famously lacking of automated test inline with it’s famous “move fast and break things” mantra. However, from what I’ve seen, I beg to differ.
