Problems We Solve

  • Node.js API has no TypeScript — runtime errors are frequent and hard to debug.
  • Application cannot handle concurrent UK users — blocking I/O and performance issues.
  • Previous UK developer built Node.js without tests, documentation, or error handling.
  • Real-time features (WebSockets, SSE) are broken or unreliable under load.
  • Node.js microservice architecture is unmaintained and deployment is manual.

Use Laravel when: the project is data-heavy with complex business logic, UK GDPR data handling is central, or the team prefers opinionated PHP architecture. We deliver both.
