Calls App.

Internal call-centre operations platform, built solo end-to-end

Internal product

What I built

  • Solo end-to-end developer: built the platform from data model to UI, integrating call centres and their data — including a legacy MSSQL 2008 database — with all integrations delivered single-handedly.
  • Delivered third-party integrations (Zendesk, HubSpot) and Azure services.
  • Designed the UI/UX, implemented type-safe validation with Zod, and robust data-management flows for operational data.
