Senior iOS Engineer
I build aesthetically refined, obsessively polished subscription apps for iPhone and Mac, where engineering, UX, and revenue are the same discipline.

Selected work
Consumer creative tools, fintech, open-source SDKs, and the indie apps I design and ship solo.
My role: I built the core editor experience on Content Arcade's flagship design app. I shipped multi-layer selection (select, group, and move layers together in the canvas), built iCloud drafts sync that keeps a design perfectly in step across iPhone, iPad, and Mac, and cut the app size in half without cutting features.
My role: I built Twinly solo, an on-device app that finds which of 9,675 film and TV actors you most resemble, and the selfie never leaves the phone. Vision locates the face and its landmarks, a similarity warp aligns it to the ArcFace template, and a 6.6 MB Core ML model turns it into a 512-dimension embedding. A single Accelerate matrix multiply ranks every actor, then a calibration curve maps the top matches to an honest percentage. There is no networking code in the app at all.
My role: I design, build, and ship Kindbloom end to end as a solo indie developer. It turns a few kind words into a hand-painted-looking poster on a live canvas, with the text, colors, and layout all editable in real time, then saved or shared in a tap. It runs on device and keeps anything personal off the network. Free on the App Store.
My role: I developed Kinde's open-source authentication SDK for iOS. I implemented OAuth 2.0 passwordless flows that stay secure and pleasant on mobile, generated a type-safe API layer with OpenAPI Generator, and wrote the unit tests and release documentation other developers depend on.
My role: I worked on the official app of Qatar's national fuel company, where drivers pay at the pump without leaving the car. I shipped scan-to-pay with Apple Pay and push notifications, revamped the UI end to end, and hardened the payment surface with SSL pinning and jailbreak detection.
My role: I built the template system for this small-business invoicing app: 30+ invoice templates as fully responsive native UI, with one layout system rendering pixel-precise documents from an iPhone SE to a 12.9″ iPad Pro.
Expertise
From the first line of Swift to the funnel dashboard that proves it worked.
Experience
7 years across consumer creative tools, fintech, and developer SDKs.
Senior engineer across client products. Shipped WOQOD's scan-to-pay with Apple Pay and hardened it with SSL pinning and jailbreak detection, built Kinde's open-source OAuth 2.0 SDK with OpenAPI-generated APIs and full test coverage, and moved the whole workflow AI-first with Claude.
Consumer creative tools at scale. Built Logo Maker's multi-layer editor and iCloud drafts sync across iPhone, iPad, and Mac, cut its app size in half, and shipped Invoice Maker's 30+ responsive templates. First deep dive into subscriptions, paywalls, and what actually converts.
About
I've spent 7 years on Apple platforms because they reward the thing I care about most. The last 10%. The animation curve. The haptic. The layout that holds on every screen size. That's usually where an app stops being functional and starts being good.
The work kept following a pattern. Something genuinely hard under the hood, like layer systems, iCloud sync, OAuth flows, and payment security, made to feel effortless on the surface. Users never see the hard part. That's the point.
Somewhere along the way I fell into the business side of apps. Paywalls, trials, StoreKit, and the A/B tests and BigQuery funnels that prove which of them actually convert. It turns out shipping beautiful things and shipping profitable things are the same skill, practiced twice.
These days I work AI-first, with Claude, Claude Code, and the modern toolchain, for deep research, rapid prototyping, and shipping AI-powered features. It multiplies what one engineer with strong design instincts can deliver. This site is the proof. Researched, designed, and built exactly that way.
Outside of client work I'm driven by fitness, creativity, and art, and by building indie apps and mentoring engineers who are earlier in the same journey I started in 2019.
Beyond code
The hobbies aren't random: they're all reaction time, framing, and craft.
Milliseconds matter. Same reason I care about 120Hz scrolling.
Frame data is just performance profiling with a health bar.
Composition, light, and restraint. The same rules as good UI.
Pacing and motion. Every good app transition is a good cut.
Click and type the line. Every key thocks.
Playground
A tiny macOS, built from scratch for this page. The windows drag, the dock magnifies, the clock is live, and everything links somewhere real.
