Ten years of craft in iOS.
I build for the Apple ecosystem — iOS, iPadOS, tvOS and visionOS. From live transit tracking to streaming at scale, and most recently a finance app I shipped alone, backend included.
The pulse is shared code reaching each platform. Hover one to see what shipped there.
Only what shipped to the App Store, or what a lot of shipped apps were built on.
Budgeting that follows your pay cycle, not the calendar month.
How it's builtA Cloudflare Worker holds the vendor keys and serves routing config from KV, so the app never calls a model provider directly. On device SwiftData persists the cycles, one cycle-scoped calculator owns every derived figure, and AI replies cache by prompt hash.
Live bus tracking, routes and ticketing for a major UK operator.
How it's builtSwiftUI on Clean Architecture and MVVM, modular where it needed to be. Google Maps carries routing, live location and stop-level updates, with Atomic Design in the view layer. The live vehicle feed arrives over a WebSocket and is normalised in the network layer, so the view layer never sees the wire format.
One codebase shipping eighteen streaming apps across iOS, tvOS and visionOS.
How it's builtBuilt on CommandBuilder, Template, Interactor and Router with protocol-oriented design and dependency injection. UIFocus Environment drives tvOS remote navigation, and accessibility was built across the whole platform from scratch rather than retrofitted late. Each brand carries its own design tokens and Figma configuration outside the shared core, and the backend drives UI and component placement.
Ten years across six domains. The early ones taught me Objective-C; the later ones are why I write Swift the way I do.
Five things I believe, and the work that had to pay for each one.
A value computed in two places will disagree eventually — and I would rather ship three similar lines than one abstraction invented before it was needed.
func freeToSpend(in cycle: PayCycle) -> Decimal
// one owner — Home, widget and AI all call itCoverage past 90% was never the goal. It was the price of changing shared code on a Friday and still sleeping that night.
@Test func unpaidManualRecurringReducesFreeToSpend()
@Test func thinkingBlockBeforeTextBlockStillParses()A focus engine retrofitted late is a rewrite, not a feature. Building VoiceOver and tvOS Focus from scratch cost less — and decided how the view layer was shaped.

}An agent may draft; I review every line and never ship what I cannot explain. Ten years in, the willingness to relearn the tools is worth more than any framework I already know.
Not a list of jobs — the four times the question I was being asked changed. The tools beside each one are the honest record of what a decade actually looks like.
Every choice was made on behalf of teams I would never meet.
18 apps · 2 brands · 3 Apple platforms
The question stopped being “does this work” and became “what does this cost whoever inherits it.”
The codebase taught me more than any course could. Feature flags, design tokens, XcodeGen, interactors and templates, dependency injection, an AppObserver pattern that keeps AppDelegate almost empty — reading code that good is its own apprenticeship.
The first place a mistake would cost someone money, not a session.
6 product lines in one app — loans, cards, insurance, investments, UPI, EMI
Convenience stopped being a neutral word to me here — a shortcut through an auth boundary is a promise you are making on the user's behalf, whether or not you meant to.
Writing for other developers, where an awkward API costs someone their afternoon.
Muvi's customers stood up their own streaming services on what we shipped.
A services shop, Objective-C giving way to Swift one project at a time.
This is where I hit the things nobody teaches you: project-file conflicts, why code needs a repository at all, animation timing, and SOAP and XML that did not want to be parsed.
I stayed because of what I could see underneath it. The tools for building here, and the standard the platform holds you to, were better than anything else I had touched — and every piece of knowledge made the next piece easier. It compounds. That is the whole reason I am still at it.
