I’m a senior iOS engineer with 12+ years of experience building and shipping mobile products, primarily in Swift, SwiftUI and UIKit. I’ve worked across consumer apps, SDKs and platform-level components, both as an individual contributor and in technical/team leadership roles.

Most recently at GlobaliD/USBC, I worked on a Swift 6/SwiftUI identity and messaging app, including secure messaging, digital identity, KYC integrations, wallet functionality and modern Swift concurrency. I also became heavily involved in AI-assisted and agentic development workflows, using coding agents together with tools such as Linear, Figma and GitHub.

Before that, at Outfit7, I worked on SDK and platform infrastructure used across multiple games. I owned a reusable compliance module, worked on ad-mediation SDK integrations and built bridges between Unity and native iOS. Earlier in my career I led iOS teams and delivered products ranging from media and IoT applications to health and fitness apps.

I also enjoy building products independently. My projects have involved HealthKit, Apple Watch, ActivityKit, MapKit, CloudKit/Supabase and AI/LLM integrations. I’ve worked on digital mental health products as well, including an incubator-backed product where I led iOS development and used HealthKit data together with AI for coaching and trend analysis.

I’m strongest when I can take ownership of a product or technical area rather than just implement isolated tickets. I enjoy architecture and difficult engineering problems, but I’m pragmatic about it — I prefer simple, maintainable solutions over unnecessary abstraction. I’m also comfortable working directly with product, design, backend and other stakeholders.

I’m currently interested in Senior, Lead or Staff-level iOS roles, particularly product-focused teams where I can combine hands-on development with technical ownership and mentoring. Native iOS remains my main area of expertise, but I’m especially interested in teams working with AI, SDK/platform engineering, health/fitness, developer tools or technically ambitious consumer products.
