@johnrenken
Fraud and dispute investigations specialist with AT&T experience resolving account issues and verifying fixes on ECHO.
United StatesWhat I'm looking for
At AT&T, I researched and resolved billing, account, and technical disputes across phone and chat, documenting each case in Salesforce with 100% account-update accuracy. I handled confidential customer information, de-escalated customers on the retention desk, and contributed to a 20% improvement in retention.
On ECHO, an independent AI assistant platform project, I reproduce defects, trace root causes, and document evidence before accepting a fix. Live testing caught three of four alert channels failing silently, and I documented the issue and verified the repair. I’m also seeking a remote fraud, dispute, or investigations specialist role.
