Work experience

Staff DevOps, Soundhound AI (2025-2026)

• Infrastructure Modernization & Risk Mitigation: Orchestrated a zero-downtime migration of three legacy subsystems, containerizing a core service to Kubernetes and establishing a blue-green deployment strategy via new VM instances; mitigated the total absence of automated tests by validating system health through rigorous log and performance analysis, unblocking urgent commercial updates.
• High-Scale Architecture & Data Engineering: Redesigned a failing core ingestion and ETL pipeline to continuously handle 400 RPS; successfully solved a multi-year scaling bottleneck that had previously degraded application performance, restoring data accuracy and system stability.
• Legacy Recovery & Partner Delivery: Spearheaded the high-risk modernization of a mission-critical system from Java 5 to 21 without existing documentation or test suites; reverse-engineered the platform via rigorous manual testing to restore a long-defunct database integration critical to external partner integration.
• FinOps & Infrastructure Auditing: Audited deployment automation and runtime architecture to uncover a critical configuration bug that left high-compute VM instances (80 CPUs and 400G RAM each) orphaned from the load balancer for years; decommissioned the redundant infrastructure to slash subsystem costs by 50% with zero impact on production capacity.
• Technical Leadership & Rapid Onboarding: Accelerated cross-departmental engineering velocity by optimizing onboarding workflows and documenting obscure systems; successfully reduced a peer engineer's onboarding time on a massive project from months to three weeks while up-leveling interviewing standards for candidate screening.
