ENTRY 04/POSITION

On the record.

I've been the CTO who answers for the database at 3 a.m. — twice. The work is JavaScript end to end: marketplaces, booking systems, crypto payment infrastructure. Systems with real users, real money, and real edge cases.

01

Business first

Map how the product makes money before writing any code.

02

Schema before screens

Data models and API boundaries come first; every feature after gets cheaper.

03

Interfaces that explain themselves

Complex workflows compressed into screens nobody needs a manual for.

04

Boring deploys

Performance budgets, readable code, software the next developer moves fast in.

ENTRY 05/REGISTRY
