About this gig

Need a POS web app that keeps working even when the internet goes down?


I develop custom POS systems and offline first web applications that help businesses continue processing sales, managing inventory, and serving customers without interruptions.


Whether you need a retail POS app, restaurant POS solution, or custom business software, I can build a reliable system tailored to your workflow. Your application will securely store data offline and automatically synchronize with the cloud when connectivity returns.


What you can expect:

  • Custom POS web app development
  • Offline first architecture
  • Background cloud synchronization
  • Inventory and sales management
  • Responsive and user-friendly interface
  • Scalable software development


I focus on delivering clean, maintainable, and business-ready solutions that improve efficiency and reduce downtime.
