iOS, shipped · solo engineer
A charisma app on the App Store. Conversational AI on iPhone, wrapped in a product real people use in the wild.
§ portfolio
Fifteen years of shipped work.
Web, mobile, VR, IoT, blockchain, and now AI. None of my competitors in the audited SMB lane claim more than web plus backend; this is the cross-platform moat.

AI companion at withami.ai · solo engineer
32+ languages, a 3D avatar, and a real-time conversational loop. Live at withami.ai.
2024
The Bureau Orlando
escape-room IoT + RFID · software lead
Award-winning immersive installation recognized by USA Today and TripAdvisor. I shipped the IoT/RFID backbone that keeps a room full of paying guests in sync.
2023
Polygon Mayhem
iOS game · engineer
An iOS title that taught me the parts of Swift and Metal I still reach for when an AI-UI needs to feel physical.
2022
Fantom Survivor
Web3 game · engineer
On-chain survivor-style game on Fantom. Part of the cross-platform moat: I have shipped contracts, not just scripts.
2022
Heroes Tale
VR RPG · engineer
Unity + C# VR RPG. Proof that I can hold a frame budget, not just an API budget.
2021
Slothtopia
Kickstarter 334.8% funded · Lead SW Engineer
Owned the platform build end to end. Funded at 334.8% of goal on Kickstarter, which is the only metric that matters for a Kickstarter launch.
2020
The CMP Hong Kong
booking system · Full Stack Engineer
Rebuilt the booking funnel. Conversion moved up fifty percent. The pattern I reuse now in the AI Booking Systems service.
2020
Metaown
Unity 3D prototype · Lead SW Engineer
Prototype work in Unity 3D. Notable here because it gives me the Unity muscle memory to build lightweight 3D surfaces for AI products without a separate 3D contractor.
