02 · Overview
What it does.
Battery service locator for TAB across Serbia. The driver use case is unforgiving: it's the side of the road, the rain, the dead battery. App goes from cold open to nearest service centre in two taps, call, navigate, request roadside assist. Full directory available offline because cell service in those moments is exactly what fails first.

04 · Decisions
The choices that shaped the build.
Tech is downstream of decisions. These are the calls made early enough to compound the right way. The ones a code review six months later still agrees with.
End-to-end ownership
One engineer from schema to deploy. Removes the most expensive failure mode in product builds — the seam between specs and code where intent dies.
Schema before UI
Data shapes first, screens second. The frontend is a view of the data, not a parallel reality. Saves weeks of rework when scope shifts.
Boring tech where it matters
Relational stores for payments and ledgers (ACID is non-negotiable), document stores for content, Redis for cache. Pick the dull tool for the dull job.
