Whether you need to sync data between platforms in real-time, automate internal tasks, or build custom middleware, I handle the backend complexity so your software runs seamlessly.

What I Can Do For You:

  • Custom Webhooks: Real-time event notifications and bidirectional data synchronization.
  • RESTful & GraphQL API Development: Custom backend endpoints built specifically for your application.
  • Middleware & Automation: Custom script execution via Node.js, Python, or integration tools like Zapier and Make.
