The Challenge 🚧

At a Trinity Wizards, our release process was broken:

  • 4 long-lived env branches — dev, staging, preprod, production
  • Human error — wrong commits shipped, hotfixes lost between branches
  • No automation — manual cherry-picks, merge conflict roulette
2+
hrs/week lost per feature

The Solution 💡

I proposed a single-branch strategy with feature flags and environment-based configuration.

As a new joiner, it took 1.5 years of advocacy — RFCs, proof-of-concepts, and persistent conversations with leadership.

The hardest part wasn't the code. It was changing minds.

The Results 🎯

3x
remove code duplication
(before 3 branch copies)
2+
hrs/week reclaimed
per developer
100%
prevent cherry-picking & conflict resolution bugs

A good engineer writes code that works.
A great engineer builds systems that make the
whole team better.

It ain't much but it's honest work meme

Why me? I've shown here that: 🏆

Everything Engineered — I practice systems thinking
Quality Certified — I try to do increments properly
High Vis — I communicate openly and lead by example

“Multiply the engineering power of the built world” — that's a mission I resonate with
