Fastsusu

The Challenge

A US fintech client wanted a group savings app where friends and communities pool money together. Referral rewards had to resist abuse, bank withdrawals needed live balance checks, and private groups had to keep their data hidden from everyone outside.

The Solution

We designed and built a cross-platform mobile app around one loop: discover a group, join it, contribute, track payouts and withdraw. Admins set contribution amounts, frequency and start dates, while members link a bank account, follow payouts and chat inside each group.

The Impact

Private and public savings groups with custom rules
Bank withdrawals with real-time balance checks
Payout tracking from collection date to payout
Built and delivered for a US-based client
Our scope: UX design, mobile app, backend APIs, secure login and testing

EmoTales

The Challenge

Parents wanted bedtime stories that felt made for their own child, not the same recycled templates every night. Writing a fresh story after a long day is tiring, and most apps support only one language, which left many families without stories that felt personal.

The Solution

EmoTales starts with a simple tap: a child picks a few emojis and AI turns them into an illustrated story in about a minute. Each story gets its own images and voice narration in the family’s language, with separate profiles for every child.

The Impact

Rated 5.0 on Google Play from 13 reviews
A full story from emojis in about 60 seconds
Multilingual stories with voice narration
No third-party ads shown to children
Our own product, built and maintained in-house on Android and iOS

CoreX Messenger

The Challenge

People wanted one messaging app that is private by default, still fast on weak mobile networks, and covers chats, calls and file sharing without a subscription. Most alternatives made users pick between speed, privacy and call quality.

The Solution

We built a phone-number-based messenger where chats and calls are end-to-end encrypted. It brings together one-to-one and group messaging, voice and video calls for up to 8 people, voice notes, live location sharing and 24-hour Status updates, with a companion experience on Wear OS.

The Impact

Rated 5.0 on Google Play with 100+ downloads
End-to-end encrypted chats, group chats and calls
Voice and video calls for up to 8 people, tuned for slow connections
No data collected or shared with third parties, as declared on Google Play
Our scope: UX planning, Android app, Wear OS companion and Google Play release
