Deep knowledge of Docker, Kubernetes, and containerized microservices architecture.
Experience administering and tuning SQL and NoSQL databases.
Solid understanding of infrastructure security and applied cryptography fundamentals.
Proficiency in scripting and systems programming (Python, Go, Rust, or TypeScript).
Clear communication skills, ability to operate under pressure, and make sound technical decisions.
