How I build
One idea. Six steps. Real users.
- P1
Diagnose in writing
Before touching anything, the gap goes on paper. My own ISO 9001 diagnostic named my department's worst finding.
- P2
Rules in the database
Business rules live in PostgreSQL. The client gets no write privilege it does not need.
- P3
Tests in CI
SQL assertions against a disposable database, Vitest on the app, five-stage pipeline before anything ships.
- P4
Ship to real users
Internal tools go live for the people who asked for them, on the shop floor, the same week.
- P5
Report the KPIs
The numbers I report come out of the systems I wrote, including the unflattering ones.
- P6
Iterate
Overrides from the panel, not from a redeploy. The system changes with the operation.
Experience
Learning by doing. Since 2019.
