   Specification first

   Before writing code I write down the use cases, the state transitions and the money rules, and I record architecture decisions so the next developer knows why, not only what.

2. 02

   Tests for the expensive failures

   I test the paths that cost money when they break: a payment confirmed twice, a failure right after a charge, two people taking the last slot.

3. 03

   A shared starting point

   At AAIT I was the main contributor to the internal Laravel starter kit the backend team built on: base services, API error handling, settlements and scaffolding commands. Around 8 to 10 developers used it on more than 15 projects.

   A workflow for AI agents

   I built a workflow that cuts a design file and a business analysis into small feature packs, then has AI agents implement each one under the architecture rules I write. I review every change and own the decisions. I taught it to other developers. My earlier projects were written entirely by hand.
