Prior to joining ASU, I worked as a Senior Software Engineer at Zeta, Directi with the Express payments division for over 3 years. I got exposed to various technologies while working at Zeta. I built an end to end payment solution using NFC stickers which contributes to 1 million+ monthly transactions. The project taught me about the memory structure, authentication mechanisms, NDEF message protocol and programming using APDU command while interfacing Android and Windows devices with the NFC chips. I was later able to extend it to deliver an embedded NFC solution with Zeta’s prepaid RuPay and MasterCard solutions.
When we forayed into the cafeteria payment space, I led the project to build an Android-based ordering system for POS devices integrating the app with a thermal printer and smart card readers. Catering to the cafeteria scenario demands high resilience. I built an entirely offline solution where both the merchant and user can remain offline while making a transaction, bringing the downtime to 0 during server outages.
I worked unaided to fully automate the deployment of Kiosk, self-serve devices bringing down the SLA from 7-10 days to less than 30 minutes by building an Electron-based application that burns the Raspbian OS and modifies the boot sequence to configure the device on first boot. The firm recognized my efforts, and I was one of the two employees in the organization to be rated as a stellar performer, the highest awarded rating. My experience at Zeta has instilled me with the confidence to tackle any problem even during a high-pressure situation.
