Convert HTML Timesheet App to iOS/SharePoint App

We are looking for a developer to convert our existing HTML timesheet application. The ideal scenario would be 365 Power Apps that integrates with SharePoint (Power Apps, Power Automate developer needed). This could then be further developed to complete service reports, etc.. The goal is to ensure that our staff can efficiently access and utilise the timesheet on their phones or iPads. The ideal candidate should possess experience in mobile app development and familiarity with SharePoint integrations. If you have a keen eye for user interface design and can ensure a smooth user experience, we would love to hear from you!
