I validate resilient AWS financial platforms through non-functional testing, production support, and distributed-system analysis.

At London Stock Exchange Group, I validate business-critical financial platforms on AWS, covering performance, capacity, stability, failover, release readiness, and production verification. I investigate issues through Linux logs, SQL validation across Oracle and PostgreSQL, and Kafka data-flow testing.

Previously, I tested Audi and Mercedes-Benz MBUX infotainment platforms at Luxoft, including vehicle-level ECU, CAN, Ethernet, DLT, Wireshark, and HMI validation. Across financial services, automotive, and telecommunications, I work closely with development, DevOps, product, and business teams to resolve defects and deliver reliable releases.
