network-engineer
Debug network connectivity, configure load balancers, and analyze traffic patterns. Handles DNS, SSL/TLS, CDN setup, and network security. Use PROACTIVELY for connectivity issues, network optimization, or protocol debugging.
When & Why to Use This Skill
The Network Engineer skill is a specialized technical assistant designed to streamline network troubleshooting, infrastructure configuration, and traffic analysis. It excels at diagnosing connectivity issues, managing DNS records, configuring load balancers (Nginx, HAProxy, ALB), and implementing robust security measures like SSL/TLS and firewall rules. By providing actionable diagnostic commands and optimized configuration templates, it helps engineers maintain high-performance, secure, and reliable network environments.
Use Cases
- Troubleshooting complex connectivity failures across different network layers using diagnostic tools like ping, curl, and tcpdump.
- Designing and deploying load balancer configurations to ensure high availability and efficient traffic distribution for web applications.
- Managing SSL/TLS certificate chains and resolving HTTPS handshake errors to ensure secure end-to-end encryption.
- Optimizing global content delivery through CDN configuration and cache strategy analysis to reduce latency.
- Auditing and implementing network security groups and firewall rules to protect infrastructure from unauthorized access.
