摘要Abstract

I build across the stack: an AI platform for founders, a bank's OpenAPI service in the middle of a database migration, a trading stack from an empty repository. Different domains, same job. Make the system hold up when real people and real money touch it.

The interesting work isthe part nobody scoped.

  1. Ship the whole path

    Frontend, API, migration, the part nobody scheduled. A feature is not a pull request.

  2. Boring where it counts

    Auth, money and data get the least clever code I can write. The risk belongs in the model, not the plumbing.

  3. Learn the domain

    Credit risk, order books, publishing queues. The code is downstream of the model, so read the model first.

  4. Leave a trail

    Tests, docs and dashboards are how the next person moves faster than I did.
