- Practical experience with Kubernetes, including understanding its impact on performance and scalability.
- Hands-on experience with tools like eBPF, flame graphs, and other profiling techniques inspired by Brendan Gregg's methodologies.
- Familiarity with cloud services (AWS, GCP) and their database offerings (e.g., RDS, managed PostgreSQL/ClickHouse).
- Experience optimizing global network performance using cloud tooling to leverage edge caching, early TLS termination, HTTP protocol optimization (e.g., HTTP/2/3 or QUIC), etc.
