iOS & Mobile Development

Writing Swift since the year it launched in 2014. Front-end full stack — pixel-perfect UI through every era of Apple's frameworks, used by millions at CBS Sports and Paramount.

Front-End Full Stack

That's the niche. I've owned every layer a big iOS app has — CI/CD pipelines, GraphQL data layers, an AppDelegate rewritten from Objective-C to Swift with a hundred dependencies attached — but my center of gravity is the screen itself. I design in Figma and Sketch, build in SwiftUI, and polish until the spacing, motion, and feel are exactly right. Five AIs make me faster; the eye stays human — I catch what the models miss. And when Apple ships a new framework, I want to be first to market with it.

Career Timeline

CBS Sports app icon

CBS Sports / Paramount

Senior iOS Developer

Drove major feature ownership on one of America's most-used sports apps, where live game days bring some of the biggest traffic moments in sports media. Led the deep dive into SwiftUI that gave the team confidence to commit to the framework long-term. Works daily in Swift with GraphQL and Apollo for data access — from schema evolution through code generation — building complex, state-aware user flows with dynamic filtering systems and carousel-based interfaces. Also modernized the app's core lifecycle: rewrote the AppDelegate from Objective-C to Swift and introduced a SceneDelegate, with roughly a hundred dependencies attached.

Contributed across a wide range of features spanning the full app surface — consistently handling rapid context-switching with enthusiasm. Recognized as a positive, grounding presence on the team: thoughtful PR feedback, close partnership with product and design on scope and specs, and a steady hand in keeping the engineering culture healthy.

What my colleagues said

I worked with Seth on a well-funded mobile application start-up. He is an iOS guru. Aside from being one the most talented developers I have met, he is, by far, the most dedicated. Seth is a team player and is someone you can trust to achieve a project. Not only would Seth find a solution, he would find the best solution. I would highly recommend Seth for any size of iOS project and consider him at least a Lead/Senior iOS Developer, completely capable of spearheading a project and leading a team.

Evan Williams AI Systems Architect | Salesforce Expert | US Army Veteran Senior to Seth · May 2018

Seth is very passionate about mobile and software development. He takes pride in his work and continues to strive to be his very best, day in and day out. Working directly with Seth, I have learned many iOS development skills such as Git, debugging, continuous integration, and even Apple's language Swift. Seth is a very great teacher, no matter what the subject is. Seth is a very strong asset to any team and company.

Key Strengths

Pixel-Perfect UI

Custom animations and polished interfaces are what I'm known for. I work closely with design teams to make every interaction feel intentional — and I still catch the details AI misses.

First to New Apple Frameworks

I love being first to market. I led the SwiftUI commitment at CBS Sports while it was still a bet, and every WWDC drop goes straight into working code — Liquid Glass included.

Full-Stack Utility

Every big app needs someone for the unglamorous middle: CI/CD shipping dev, UAT, and prod builds; GraphQL data layers; codebases scaled from 50 to 1,000+ compile sources. I've been that teammate — it's why my front-end work ships without friction.

Performance as a Feature

Launch time, scroll smoothness, frame pacing — I profile with Instruments and treat performance like a product requirement, because users feel it before they can name it.

Accessibility as Craft

VoiceOver labels, Dynamic Type, reduced motion — the details that make an app work for everyone. This site ships skip links, focus states, and reduced-motion support; it's the same bar I hold app work to.

Mentoring & Review Culture

Colleagues call me a teacher. I give thoughtful PR feedback that raises the bar without slowing the team, and I've mentored developers from their first commit to shipped features.

Design & UI/UX

Mobile development and design go hand-in-hand. I don't just build what designers hand me — I design, prototype, and ship interfaces from scratch, including apps I was hired specifically to design. My design work has spanned app UI, branding, marketing assets, and more.

App UI Design

End-to-end app design and development. Designed and built the Energy Sense Finance app from scratch. Contracted to design and build RedSwipe in Xamarin with full UI, QR code scanning, and branded experience.

Graphical Instinct

Personal design portfolio spanning mobile interfaces, branding concepts, and visual design work. A creative outlet that keeps my design skills sharp alongside engineering.
