V.2.5.0 // NATNAEL AI
Solo Full-Stack & Mobile Engineer
A production ride-hailing platform with passenger & driver apps on iOS/Android, featuring fraud-proof NFC boarding verification, resilient background tracking, and real-time coordination — built and shipped solo.
"NFC isn’t just a gimmick — when used for identity, it becomes the most secure and delightful way to solve real-world trust problems in ride-hailing."
Ride-hailing fraud (wrong car boarding, fake drivers) and unreliable tracking when apps crash or phones restart are major pain points in emerging markets. Traditional PIN/QR solutions fail constantly.
Engineered a Flutter-based dual app (Stacked MVVM) paired with a Node.js/Socket.IO backend. Introduced physical NFC tags for 100% accurate driver verification and NFC business cards for contactless profile sharing. Built crash-proof location tracking and server-side trip continuation.
Flutter (Stacked MVVM) + Node.js/Express + Socket.IO + MinIO + MongoDB/Redis stack with NFC hardware integration
Mood Ride is a full-stack ride-hailing platform I built from scratch that rivals Uber/Ola in core functionality — with one killer twist: NFC-based driver identity verification to prevent fraud and man-in-the-middle attacks common in emerging markets.
Live location tracking, dynamic fare calculation, and real-time coordination all continue seamlessly even if the app is killed or the phone restarts.
In many African and Southeast Asian cities, ride-hailing fraud is rampant:
Traditional solutions (QR codes, PINs) are clunky and easy to bypass.
I introduced two NFC innovations:
This turned a security liability into a delightful, futuristic experience.
