About this gig

I am a Full-Stack Developer working professionally on web applications, back-office systems, APIs and business integrations.


In my free time, I also develop projects such as FinHub and the Ser Riquinho back office, where I work with dashboards, user management, financial tools, API integrations, automation and custom features.


I can help you with:

  • Adding a new feature to an existing system
  • Connecting platforms through APIs
  • Automating repetitive processes
  • Fixing or improving existing functionality
  • Building small custom web applications
  • Creating dashboards and back-office tools


I focus mainly on small and medium-sized projects with clear requirements and realistic delivery times.


Please contact me before ordering so I can understand your project and recommend the right package.
