API & Backend Systems

Systems that don't talk to each other cost you hours of copy-paste. Secure APIs connect your apps, payments and tools so data flows on its own.

  • ASP.NET Core Web API
  • Entity Framework + Dapper
  • JWT & OAuth2 authentication
  • Microservices & event-driven architecture
  • Azure Service Bus, Functions & queues

  • MLS & IDX integrations
  • Advanced property search & filters

FAQ

Common questions

Everything you need to know before we start working together.
