Agents on the team, held to the same bar.

A cloud agent I built takes small bugs from ticket to pull request: it diagnoses, fixes, verifies, and attaches a screen recording of the fix in action.

2014 · Apostek Software

And it all started with games.

My first job: Objective-C games, where every frame and every animation is felt.

Slot Machine, a top game in its category: built the "High or Low", "Scratch Card" and "Lucky Pot of Gold" mini-games to lift session length.
Solitaire 2.0 from scratch, with game logic on trees, hashes and doubly-linked lists.

Stack

The stack, with receipts.

Every tool here has shipped something real. Hover or tap a tile to see what.

How I work

Four habits behind the numbers.

Architecture first.

I set module boundaries early, so teams build in parallel and the app scales without a rewrite.

Module architectures at DocOn; the app architecture at Thinkific.

Measure, then optimize.

Profilers before opinions. Every performance claim ships with a before and an after.

37.5x faster Core Data fetch · 12.5x faster course load

Automate the toil.

If the team does it twice, I script it. If it's routine engineering, an agent does it, and a human reviews it.

2 days → under 2 hrs setup · 1 month → 4 days with automation

Raise the bar around me.

Mentoring, code reviews and talks, so the whole team ships better, not just me.
