The build.
Indonesian Stock Exchange disclosure data tool — surfaces public company filings with structured queries.
What I learned.
01
Start from the failure mode.
Define what 'broken' looks like before defining what 'working' looks like. The contract follows.
02
Single source of truth.
Whether it's a CV file or a domain entity — pick the one canonical place it lives, and shape the rest of the system around reading from it.
03
Boring tech, novel problem.
The interesting part is the problem framing. The stack should be the dullest viable option.
Outcome.
Shipped to a small audience or running for personal use. Available to walk through privately.
