• Champion engineering best practices through code reviews, technical documentation, and participation in architectural decision records (ADRs).

Skills

• Hands-on experience with UDP/TCP socket programming, binary protocol parsing, and high-throughput data ingestion pipelines.

• Demonstrable experience in a production setting handling NetFlow, sFlow, or IPFIX at enterprise scale.
