ID checker process

ID Checker

A coworker and I created a web based ID checker for Sunrise UPC LLC, yallo, and Lebara. Together we designed the technical flows and customer journeys, we then built a frontend where customers can scan their ID documents, and another frontend for agents to approve those documents. We also built a rest API to handle communications between these two frontends and the CRM systems. Angular, Web RTC, PHP, and SCSS.



Sprink was a startup that I created together with my Brother and Step-Dad. The initial drive to create Sprink was as our own way to support local dry cleaners in these difficult times of the Covid-19 lockdown. Sprink was founded with the goal of transforming the declining dry cleaning industry into a growing one by incorporating modern technology and trend-setting innovations. Angular, Stripe, MongoDB, Node.js, and SCSS.
