How I Build Mobile Workflows and Improve Their Business Value
Vlore: securing a physical interaction
I developed React Native functionality for Vlore, an application for scanning, writing and managing NFC tags and physical assets. I implemented a cryptographic CMAC protocol using NTAG 424 DNA hardware and built a secure authentication layer for tap-to-verify validation.
The outcome was encrypted authentication around an NFC interaction. My work connected the mobile application with the security behavior of the hardware. This is a specific example of the architecture and implementation I handled: the app needed to do more than read a tag; the interaction included cryptographic validation.
Keventers and Nizams: connecting orders, payments and delivery
My food-service mobile work included Keventers and Nizams applications with order tracking, payment integration and real-time updates. The stack included React Native, Redux, Node.js, Stripe and Google Maps. These applications supported food ordering and multi-store operations.
I worked on the functionality that connected the customer’s order with payment and delivery information. The result was a mobile workflow covering those steps in the product. This work demonstrates how I connect mobile interfaces with the backend and third-party integrations needed for business operations.
Fuboot and Agro Finance: building around financial records
On Fuboot, I worked as a React Native developer on community financial pooling and contribution tracking, with SQL optimization included in the project work. Agro Finance addressed annual finances, crop planning and agricultural operations using React Native, SQLite, charts and push notifications.
The applications served different users, but both centered on making operational information available in a mobile workflow. Fuboot supported group contributions; Agro Finance supported planning and financial visibility for farmers. My contributions included the application functionality and, for Fuboot, database optimization.
Contact capture and membership workflows
I engineered mobile OCR functionality that scanned business cards, extracted contact information and populated application forms. This reduced the need to enter those details manually. My Tactlink work covered a business directory and networking application published on iOS and Android.
I also developed membership workflows for The Chenab Club, including event booking, member directories and facility reservations. These examples show the business outcomes my mobile work supports: capturing contact data, connecting professionals and helping members access services through an application.
I’m Abaid Ullah, a Full Stack AI Software Engineer open to opportunities in this area.
I develop cross-platform mobile applications for business workflows, including NFC tools, networking, financial pooling and multi-store food ordering. My mobile experience includes React Native applications published on mobile app stores.
