At Upwork, I create Android applications to meet client requirements, including a health app using the Health API and a companion app for Watch. I also created restaurant functionality using NFC, an NFT marketplace app, and an Android VPN app using OpenVPN and IPsec.
At Identomat, I created an Android SDK used by companies including banks, casinos, and retail chains. I also worked with ML Kit for face detection and text recognition, NFC for ID cards and passports, and a Twilio video call system for banks.
