Domain Inspector

Context

A fullstack technical challenge from a hosting company's hiring process, completed: a web API that consolidates DNS and WHOIS information for any domain — name servers, A record and hosting data.

What I did

• C# / ASP.NET Core back end querying DNS servers and the WHOIS protocol
• MySQL persistence with Entity Framework
• TTL-based caching: repeat lookups are served from the database while the TTL is valid, instead of hitting external services again
• Front end bundled with Webpack / Babel

Stack

Outcome

Delivered complete, designed around separation of concerns and testability.
