Moneyworld
A bank account that plays like a Tamagotchi — nudging people to save $10–$200 a week through a game they actually want to open.
What is Moneyworld?
Saving money is boring, so most people don't. Moneyworld's bet was to hide a real, FDIC-style savings account inside a Tamagotchi-style world — you feed a character, grow a tree, complete daily quests, and every action maps to a small automatic deposit.
The habit loop is the product: open the app, do a couple of quick things, watch your pot grow, come back tomorrow. Behind the cartoon is a hard problem — a real-time game engine and a regulated banking backend have to feel like one seamless app.
I owned the app end to end.
In a small, fast-moving team I led the mobile product — from architecture decisions to what shipped.
Led the entire React Native frontend — architecture, state, the animation system, and every screen users touch.
As a key early engineer I helped set technical direction, made the build-vs-buy calls, and unblocked the team.
Took features from blank page to store, then iterated fast on real user feedback to fix UX and lift engagement.
Make a bank feel like a game — without breaking either.
Real-time game feel — animations, sound, live multiplayer — running next to money movement that has to be exact and secure.
A daily habit loop strong enough to change behavior, on a smartphone, for people who find saving tedious.
Startup pace — a tiny team shipping a polished, crash-free app to a store where fintech trust is everything.
Four systems, one seamless app.
The technical spine of Moneyworld — everything a user feels as one experience.
Pillar 01Core game engine
Built the complete gaming experience from scratch — a sophisticated animation system, sound effects, and real-time server integration that keeps every reward reacting the instant a user acts.
- Frame-perfect coin, confetti & reward animations
- Layered sound design tied to game state
- Live server sync so the world is never stale
Pillar 02Real-time trivia showdowns
Developed live multiplayer trivia over WebSockets — players compete head-to-head in real time for bonus rewards, with leaderboards that turn saving into a social streak worth defending.
- WebSocket rooms with low-latency state sync
- Bonus-coin rewards paid straight into the pot
- Weekly / monthly / all-time leaderboards
Pillar 03Game mechanics that build the habit
Built the systems that make people come back: an avatar constructor and wardrobe, character customization, daily quests, coin collection, and streak-based progression — the whole reason opening the app is fun.
- Avatar constructor & wardrobe system
- Daily quests & coin collection
- Streak-based progression that rewards returning
Pillar 04Banking integration
Engineered real bank-account linking and automated deposit systems, so saving happens in the background. The gamified layer sits on top of genuine, secure money movement — not points that pretend to be money.
- Secure account linking & verification
- Automated $10–$200 weekly deposits
- Game rewards mapped to real balances
It shipped, and it stuck.
A gamified habit that people opened dozens of times a day, held a 4.3★ rating, stayed effectively crash-free, and kept acquisition cost low — the whole thesis, working.
