Professional summary

Senior Test Engineer with 15+ years of experience in testing network devices, embedded/automotive software, and web applications. Experienced in designing and maintaining test automation frameworks with Python, as well as leading QA activities and managing test infrastructure across telecom, automotive, and e‑commerce products.

Currently focused on applying QA and test engineering practices to AI systems — evaluating, benchmarking, and validating models for correctness, performance, and reliability — running on ARM/RISC‑V‑based systems and distributed inference pipelines, while deepening hands‑on Python 3 expertise to build custom test tooling and automation around these workflows. Particularly interested in network device testing, IPv6/BGP, and automotive testing.
