iOS + product execution
Native app flows, progression systems, store operations, notifications, and release-minded UX.

These are not just brand names. Each one demonstrates a different mix of product taste, engineering execution, debugging discipline, and follow-through.
01
BobaHub
Commerce ops across iOS, backend services, payments, and production infrastructure.
BobaHub is a live full-stack commerce stack spanning customer and store iOS apps, admin tooling, backend APIs, and production operations. Recent work included shipping a single-VPS deployment with Docker Compose, Caddy, Postgres, and Redis; advancing store-side workflows like Brother printing and auto-ready handling; and wiring the foundations for APNs order updates and Apple Pay checkout.
- Shipped a live VPS stack with Docker Compose, Caddy, Postgres, Redis, API, admin web, DNS, and HTTPS
- Advanced iOS store operations with Brother printing, Bonjour discovery, and auto-ready workflows
- Implemented APNs order-ready notification plumbing and Apple Pay integration groundwork
- Documented and deployed the system as a real production environment, not just a local prototype

TypingMaster
Fast iteration on gameplay systems, progression logic, persistence, and interface polish.
TypingMaster is a game-like typing product designed to feel responsive, motivating, and replayable rather than instructional. Recent work included redesigning progression into a gated 7-phase evaluation ladder, repairing public progress persistence and restore bugs, stabilizing shared canvas startup across modes, and reworking the summary flow into a clearer 3-card results experience.
- Redesigned progression into a 7-phase skill-evaluation ladder mapped across 8 tiers
- Fixed real public persistence and restore issues so signed-in progress survives reloads correctly
- Reworked post-game summaries into a cleaner 3-card layout with stronger celebration and feedback states
- Stabilized gameplay startup and shared canvas behavior across standard and bonus play modes
Captured from a fresh local build for portfolio review.

Interview Prep
Structured preparation workflows with auth, persistence, and system-design tooling.
This project combines a guided prep calendar with authenticated notes, attachments, and persistent system-design sessions. Recent work split Interview Prep into a cleaner frontend-plus-backend architecture, brought up a dedicated auth service with its own APIs and database, repaired the public deployment path, and fixed canvas-state loss so saved diagram work persists through normal editing instead of silently disappearing.
- Built a separate auth/backend service with register, login, refresh, notes, attachments, and prep-state APIs
- Reorganized the project into a cleaner multi-part structure for frontend, backend, and course content
- Repaired the public deployment and Cloudflare tunnel flow so the hosted app and studio are reachable reliably
- Fixed saved-canvas data loss with regression coverage and verified restored system-design sessions in-browser

ClockRacer
A learning game that treats educational UX like product design, not homework.
ClockRacer turns analog clock reading into a real game with progression, time pressure, and performance feedback across web and iOS. Recent work included tightening guest-versus-account progression behavior, fixing leaderboard and results-edge cases, preparing iOS release builds, and continuing to refine the product loop so it feels like a genuine consumer game rather than a classroom exercise.
- Cross-platform product spanning browser and native iOS surfaces
- Leaderboard, achievements, guest/account progression, and TestFlight-oriented release work
- Ongoing UX hardening around results flows, shortcuts, local reset actions, and progression state
- Educational mechanics framed as a polished consumer experience with measurable improvement loops

BayStrings + SoCalStrings
A repeatable regional content platform for the strings community.
BayStrings and SoCalStrings are proof that careful curation can scale when the underlying content model is strong. They combine public-facing discovery UX with disciplined editorial operations: rolling event windows, source verification against official venues and orchestras, and region-specific expansion without turning the product into a generic directory.
- Built a reusable model for regional cultural discovery rather than one-off pages
- Maintained active rolling event windows with repeated verification against official sources and current programs
- Combined clean public UX with disciplined behind-the-scenes content operations and QA checks
- Expanded the same design language and data model across multiple regions without feeling templated
