Hi, I'm Jonathan.

I’m a product designer and problem solver who has fun building things that are fun to use.

My time as a venture analyst and hobbyist web developer shapes my lens for digital products. My design approach is rooted in product strategy, systems thinking, and a love for creating functional and delightful experiences.

Handoff Status and Nudging Feature, Cirqles (2025)

I conceptualized and designed a handoff status tracker and nudging feature for Cirqles, a marketplace for sharing pre-owned goods, to resolve uncertainty and reduce user drop-off during item handoffs.

Gift Card Integration in Apple Wallet (2024)

I prototyped a concept feature to add, use, and manage gift cards in Apple Wallet. The design focused on a seamless, native experience which was refined through real-world user testing and feedback.

Full-Stack App Redesign, Serao Academy (2023)

I rewrote the backend of my jiu-jitsu gym s frustrating scheduling app using AWS Amplify, resulting in 8x faster response times. Then, I redesigned it based on feedback from 100+ weekly users.

Streamlining Interview Prep with AI, Ingrain (2023)

I designed a concept AI tool that helps job seekers practice interviews and get targeted feedback. This case study explores how I reduced friction and improved feedback retention through iterative testing and observed behavior.

Visualizing Trips with Photo Metadata (2022)

I built a full-stack web app that charts journeys on Google Maps using EXIF metadata extracted from photos. I gained experience with ReactJS and back-end design using Firebase for auth and account-based data storage.

Version Control System Inspired by Git (2022)

I built a simplified version of Git in Java to practice software design using data structures and file persistence. I implemented core Git commands using Merkle tree-like logic and rigorously tested key features.
