Growth Engineer · SINCE 2017

Topan Growth Engineer

Performance marketing run with an engineer's mindset. I came up through frontend and technical support, so I read the tracking stack as fluently as the media plan, and I put AI in as a new layer, not a new job title.

STEPS
READ THE FULL METHOD

I Build.

I Ship the Product.

I Measure the Product.

I Learn the Product.

  1. 01 Build Everything that has to exist before money moves: account structure, tracking, creative, landing page. Built so each part can be read separately — when something works, I know which part did it.
  2. 02 Ship Live in market, deliberately small at first, against a CAC ceiling written down before launch. A launch is not a bet; it is a question posed cheaply enough to answer.
  3. 03 Measure Cohorts, payback and blended CAC, read honestly and on a schedule. A campaign that is running is not a campaign that works until the data has said so.
  4. 04 Learn What the numbers taught goes straight back into the next build — structure, audience, creative, or the tracking itself. The loop restarts better informed than it began.

YEARS IN GROWTH

// 2013 ────────────── 2026

// THE PRACTICE

I started in frontend engineering and technical support, then moved into performance marketing without leaving the technical side behind. Today I run paid acquisition at Gotrade (YC S19) for the Indonesian market and build XerAds, an AI-native growth platform. I am as comfortable debugging a tracking pixel as optimising a campaign budget.
