On-demand services app — Attendv / Betek

Frontend Developer

ReactFirebaseSEOCI/CD

Context

Attendv / Betek needed a web platform connecting users with on-demand services, requiring real-time dynamic interaction and strong organic search positioning.

Problem

  • No existing codebase — the platform had to be built from scratch.
  • Performance and SEO were critical for user acquisition through organic search.
  • The team was deploying manually, causing friction and release errors.

Solution

  • Built the complete web application with React and Firebase, implementing dynamic features (real-time updates, service request management).
  • Optimized performance and SEO through code splitting, lazy loading and proper metadata/HTML semantics.
  • Set up CI/CD pipelines, automating build, testing and deployment.

Result

  • Measurable improvement in load speed and search visibility.
  • Automated deployment flow, removing error-prone manual steps.
  • Maintainable codebase for continuous product iteration.
