At Payteq, I provide application and production support for a payment authentication platform, with end-to-end responsibility for EMV 3DS authentication operations for banking clients. I configure and support ACS services, issuer onboarding, tokenization, and Google Pay and Apple Pay payment flows.
I investigate production incidents using SQL, PostgreSQL, application logs, and API data, then coordinate resolution with development and vendor teams. I also monitor authentication and error rates and analyze EMV 3DS message flows, including OOB, SDK, and browser flows.
At SIBS Romania (Romcard), I configured and operated ACS and MPI platforms for issuing and acquiring banks. I supported deployments, onboarding, integration testing, transaction investigations, and tokenization and digital wallet activities.
