Jetty Health

Founding iOS Engineer

As Jetty Health’s founding iOS engineer, I built and launched an AI-powered app that helps people track chronic symptoms through natural voice and text conversations.

Own the full iOS engineering lifecycle: architecture, feature development, testing, App Store deployment, and production support.
Work side-by-side with the cofounders—including an AI/ML engineer—to translate complex AI capabilities into intuitive, reliable mobile experiences.
Shape product requirements, user flows, and priorities, translating early user feedback into shipped improvements.
Use Codex and Claude Code to accelerate development while maintaining the security, privacy, and reliability required of a healthcare product.

Independent

Freelance iOS & visionOS Engineer · Technical Consultant

Across multiple client engagements, I led augmented-reality research, prototyping, product direction, development, and App Store launches.

Built a first-of-its-kind Apple Vision Pro AR application that became one of the earliest apps on the visionOS App Store.
Developed custom features in Swift and SwiftUI using ARKit, RealityKit, SceneKit, SpriteKit, and other core Apple libraries.
Provided high-level technical guidance and product direction for early-stage and experimental projects, particularly in augmented reality.

Gumroad

Senior iOS Engineer

As Gumroad’s sole iOS developer, I owned every iOS initiative: new features, multiple app launches, backend integration, bug fixes, and release quality.

Collaborated directly with designers, product leaders, engineers, marketing, and customer support to deliver a high-quality user experience and stable App Store releases.
Adopted AI-assisted development for codebase exploration, implementation, refactoring, and review.
Accelerated iteration while retaining ownership of architecture, product decisions, and release quality.

Lead iOS Engineer

I owned multiple children’s iOS apps that merged physical toys and digital experiences, including a flagship AR teddy bear sold at major retailers.

Joined as the sole iOS developer, then built a small mobile team and a positive engineering culture across the app suite.
Led products using ARKit, Core ML, SpriteKit, and physical play to create intuitive experiences for children.
After Seedling was acquired by BEGiN, an early childhood education company, helped launch an iOS app that encouraged children to learn through real-world AR play.

Software Development Engineer in Test

I played a core role in the feature design and testability of SharePoint Online’s customer migration to datacenter infrastructure.

Drove high availability work that helped SharePoint Online meet its 99.9% uptime SLA in close partnership with operations.
Helped shepherd the engineering organization’s growth from 7 people to more than 200.
