    I need a Power Apps canvas app that lets our team search Service Level Agreement (SLA) records stored in a SharePoint list. The app’s sole purpose is SLA data search, so no extra dashboards or automation are required. Here’s the flow I have in mind: a search screen where users can type or select key SLA fields (for example title, customer name, reference number or date ranges), press Search, and instantly see matching list items. From the results they should be able to open a detail view that shows every column in a clean, phone-friendly layout. The SharePoint list is already live in Microsoft 365, so you can connect directly to it with standard Power Apps connectors. Performance matters; delegation-friendly queries and sensible filtering are important so the search works eve...

    I need a very small, self-contained prototype that shows how you would structure an “apple fruits records” application. At this stage I am deliberately keeping the brief minimal because the goal is to evaluate your approach, code quality, and communication style before we move on to a full build. Here is what the first milestone should demonstrate: • A clean data model able to store individual apple entries (feel free to invent a few sample fields such as variety, harvest date, or quality score so I can see relational thinking). • A simple screen that lists the saved records and lets me add a new one. • Clear, commented source code plus a short read-me describing the architecture and any third-party packages you introduced.
