He has delivered multi-million dollar infrastructure savings (Failover Architecture 2.0) and slashed operational timelines—cutting cluster provisioning from weeks to two hours and Kubelet upgrade time by 70%—by architecting cross-system operators and cluster orchestration. As founder of FStack Technologies he scaled a 15‑engineer consultancy to $400K+ ARR, bringing a founder’s end-to-end ownership to complex infrastructure projects. His open-source contributions include improving image caching and reliability for the well-known Singularity/Apptainer container project, reflecting deep expertise in container runtimes and robustness engineering. Passionate about capital markets, he runs a fully automated options trading system and is actively seeking to apply his platform-scale, low-latency engineering to quantitative trading or HFT. Fluent in Go, Python, C/C++, Kubernetes, Terraform, and observability stacks, he blends hands-on systems development with cross-team delivery and security-minded design.
