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.
