Seniority Shows Up First in What You Refuse to Build Restraint is a technical skill, not a personality trait

Seniority isn’t louder output.
It’s restraint.

This piece looks at how judgment shows up in what experienced builders refuse to add, touch, or complicate.

Business Constraints Don’t Kill Good Design, Unexamined Constraints Do When Rules Shape Products More Than Pixels

Design Debt Is Often Just Unacknowledged Engineering Debt When UX Problems Are Really System Problems

Many UX problems aren’t design failures.
They’re unresolved system decisions finally becoming visible.

UX Is Not the Same as Being Considerate Why politeness fades, and systems are remembered

UX and consideration aren’t the same thing.

This post is about where they diverge, and why that difference shows up fast in real use.

Micro-Interactions That Earn Their Keep When feedback clarifies state, and when it quietly becomes debt

Micro-interactions should earn their keep.
If they don’t add clarity, feedback, or trust, they’re just decoration.

Designing UI as a System Why screens are easy, and coherence is not

UI works best when it’s treated as a system, not a collection of screens.

A short reflection on system-first interface design.

ToDo When Nothing Else Existed Why this app had to exist, and why rebuilding it matters now

ToDo started when nothing else quite worked the way I needed it to.

Yea, most definitely! Awesome to finally get in touch with fellow devs as well. Btw, that’s a very cool app. I also am blistering myself on my own passion project, ToDo. It was on the App Store but I took it down due to bugs, which I’m working out now and bringing it up to speed with iOS 26.

Post an archer.

This was an exciting read. It’s a fascinating peek into the world of SwiftLang.

That’s a pretty wild ride, thanks for sharing the insight. I’ve always wanted to get a peek in the behind the scenes of swiftlang development.

Additionally, and more importantly, kudos on the fix! And on putting your mark on the build!

What iOS 26 Taught Me About Building Thoughtful Apps A reflective synthesis from four micro-apps

I wrote about what iOS 26 taught me after building a series of focused micro-apps.

It’s about intent, constraints, and learning by building.

#iOS #Swift #SwiftUI

That’s an interesting connection. I wasn’t thinking about Shortcuts, but I get why it came up. The focus here was execution boundaries inside the app, especially around async work and mutation. That discipline often makes systems more composable too.

A small iOS app used to explore background tasks, notification timing, and what happens when you stop fighting the system and design with it instead.

Async Doesn't Mean Ordered in SwiftUI aka the bug that quietly rewired how I think about execution

Just published: Async doesn’t mean ordered in SwiftUI. A field report on a concurrency bug that forced me to rethink execution assumptions and where ordering actually comes from.
