• Deep understanding of multithreading/concurrency/parallelism and failure modes in distributed systems.
• Proficient with Git workflows and CI/CD (Jenkins, Argo, Git Hub Actions, etc.); strong testing culture.

• Domain exposure to cybersecurity or intelligence platforms.
• Observability: Prometheus, Grafana, Graphite, Open Telemetry (traces/metrics/logs).
• Open‑source contributions (Git Hub, Stack Overflow, blogging, talks).
