What I'm looking for

I’m looking for a role where I can own L3 production support, investigate incidents with SQL and logs, validate REST APIs, and drive RCA that improves MTTR—working closely with engineering in an SLA-focused, high-availability environment.

I’m a Technical Support and L3 Specialist with 3+ years of experience in production incident investigation, SQL analysis, and API validation across high-availability iGaming and Sportsbook transactional platforms. I act as a core L3 escalation point, driving root-cause analysis with precise database evidence and technical findings to accelerate engineering fixes.

In production, I validate data consistency and REST API payloads, isolate transactional and third-party bottlenecks, and reduce Mean Time to Resolution (MTTR) through advanced SQL and log analysis. I also optimize incident triage processes by bridging communication between operations, front-line support, and core development teams, while keeping strict enterprise SLAs.
