What I'm looking for

I’m looking for a role where I can own quality and reliability end-to-end—virtualization feature validation, low-level network performance, and AI-assisted test automation—working with strong engineering teams that value measurable outcomes and open-source collaboration.

I’m a Principal Software Quality Engineer with 10+ years focused on virtualization development and testing at Red Hat, pairing low-level network protocol optimization with rigorous validation of virtualization core features. I’ve improved TCP/UDP behavior in user-mode networking (passt/pasta), including retransmission reliability, epoll-based TCP send tuning, and rootless Podman-friendly loopback forwarding via the --splice-only mode.

I also build AI-assisted quality systems and automation: I developed an AI-driven automated test orchestration workflow (PyTorch/TextCNN with commit-message embeddings via Word2Vec) and integrated it into CI/CD using FastAPI and Jenkins for automated prediction and test-scope reporting. In open-source (passt/pasta, avocado-vt, tp-qemu), I’ve contributed extensively—35+ PRs to frameworks and 110+ PRs to test suites—covering memory, CPU, and migration with functional, integration, and regression testing that I drive to closure.
