Rapid Prototyping and front-end for iOS App
Tom Harrison
Role: Front-end / UI-focused iOS developer
Duration: 2022–2024
Context: Fully remote, US-based startup
Outcome: Apple Featured App of the Day, 5★ App Store rating
Overview
From 2022 to the end of 2024, I worked remotely with an American startup on a neuroscience-focused iOS app built in Swift and SwiftUI. I joined early, initially to support rapid prototyping and UI exploration, and became a core member of a five-person development team.
Responsibilities
Rapid prototyping of UI and interaction ideas
Swift / SwiftUI feature development
Acting as a bridge between design and engineering
Quality control to ensure parity between design and implementation
Leading selected features from concept through to delivery
Design ↔ Development Accuracy
Ensured visual parity between design and implementation, including spacing, animation timing, and hierarchy.

Memory card system
Emotion rating interface
Contribution to overall interaction language
Implementation of the memory feed and memory card feature, highlighting full interaction flow and production-ready quality.
Early prototype exploring a radial input model for rating emotional intensity. While the surrounding structure evolved, the core wheel interaction informed the final shipped design.
Final implementation of rating system refined into a single-screen interaction with simplified structure and improved clarity, retaining the radial input model I introduced.
The app was featured by Apple as App of the Day and maintains a 4.7 star rating on the App Store.
“I worked with Tom during the early years of Matter Neuroscience. The phase was characterized by unclarity around the final consumer product to be built and various perspectives in the leadership. While hired into engineering, where he was working on key features successfully, Tom unsolicited worked on a full product vision and brief that indicated to leadership what would be needed for a faster and better engineering process. To me, a piece I won’t forget as an impressive demonstration of bottom-up leadership that pushed the company forward.”
