Overview
I have handled domain and web infrastructure from purchasing and configuring domains through DNS, hosting, server pointing, and HTTPS setup.
Work performed
I configured A and CNAME records, validated DNS changes, pointed domains and subdomains to hosted services, worked with Linux and NGINX, and used Certbot to enable TLS certificates.
Troubleshooting
This work involved diagnosing DNS propagation, record conflicts, hosting configuration, SSL, and connectivity issues when a domain did not resolve or a service was not reachable as expected.
What this demonstrates
DNS administration, domain-to-service routing, Linux web operations, HTTPS deployment, and troubleshooting across DNS and application layers.
