Hey👋, I'm Stefanos Tzortzoglou

Technical Customer Success Manager | Implementation Lead | SQL, APIs & Data Strategy
I bridge the gap between commercial goals and technical reality. I don't just manage accounts; I get my hands dirty with SQL, API integrations, and CRM/ERP data mapping to solve the technical blockers that others escalate.
Currently a Technical Customer Success Manager at Data Talks. Get in touch.
Technical Customer Success
Bridging Commercial Strategy & Technical Reality
I sit at the intersection of revenue and code. I fix the technical blockers that stall renewals. I build the solutions that get customers to value without waiting on Engineering.
Technical Execution
SQL, REST APIs, and complex data mapping.
Revenue Protection
Turning technical adoption into secured ARR.
Selected Case Studies
Global Ticketing API Mapping
Reverse-engineered legacy API logic for a global ticketing giant to standardize millions of event data points without breaking dependencies.
Fortune 500 Data Lake Strategy
Designed a "Parent/Guardian" entity model for an enterprise client so marketing reached authorised adults while minors' data stayed siloed.
Technical Utility Scripts
Automation scripts and API experiments I write outside work: parsing, data formatting, and small utilities.
Fixed, not escalated
That is the work I do at Data Talks, across enterprise accounts. If you are wrestling with an integration problem, or there is a role worth hearing about, I am glad to talk.
