Air Purifier
The challenge
What was in the way.
Air Purifier needed hardware and iot work delivered as one system rather than split across vendors — screen-based air quality monitoring with brightness and child-lock controls plus filter-change warnings.

How we built it.
We restated the brief as constraints — power, latency, cost, compliance — and named the ones that conflicted. A working slice through the riskiest layer was signed off first, then built out in two-week increments with one demo each, reviewed against the same engineering standard across hardware and software.
