Fernando J. Arocho Colom

As a Senior iOS Engineer with over 7 years of experience, I specialize in building accessible, performant, and user-friendly mobile applications using Swift and SwiftUI. My work spans across fast-paced startups and larger product teams, with a strong focus on accessibility, custom animations, localization, and composable architecture.

Most recently, at Bottle Rocket, I contributed to the Potbelly app, implementing offers and perks features using SwiftUI and The Composable Architecture. I also built a Stripe-powered "Scan your card" experience that reduced entry time by up to 60%. At Ovia Health, I rebuilt core logging features in SwiftUI, led accessibility efforts, and ensured WCAG compliance across the app — boosting accessibility coverage from 5% to 90% in two years.

Earlier, I played a key role in the Robert Half app by developing a time entry feature used by thousands of contractors and creating the company’s first iOS Widget. I also introduced custom animations and enhanced voice-over usability.

My technical toolbox includes Swift, SwiftUI, Objective-C, Vapor, Xcode, Git, and Stripe SDK. I’m experienced with MVVM, unit and snapshot testing, and multi-locale UI development. I’ve also worked with web technologies, having contributed to products like ShareLov and ATH Móvil.

Beyond the code, I’m proactive in cross-functional collaboration and value clean architecture, scalable design systems, and privacy-first approaches — including compliance with regulations like Washington’s “My Health, My Data” Act and Nevada’s SB 370.

Fluent in English and Spanish, I thrive in remote environments and enjoy contributing to mission-driven teams. Whether I’m shipping a new feature, improving accessibility, or mentoring junior devs, I focus on delivering high-quality, user-centered experiences.
