    I need a full-featured Windows desktop application that blends three core capabilities in one seamless interface: • File management – a clean explorer-style module that lets users browse, search, copy, move, rename, and organise local files and folders quickly. • Data analysis – the ability to import common formats (CSV, Excel, maybe JSON), run basic statistics, filter, sort, and generate simple visual summaries or charts right inside the app. • Integrated chat – a built-in messaging panel so users can exchange text messages and small attachments in real time without leaving the program. A lightweight local or server-based solution is fine as long as it is secure. I’m targeting modern Windows 10/11 machines, so a solid native feel is important. ...

    I need a lightweight .NET service that communicates with Epicor’s REST API and keeps our database and the ERP in lock-step. The core requirement is real-time data synchronization—changes made in either system should be reflected in the other within seconds, without manual intervention or batch jobs. Beyond simply moving records back and forth, the service must apply custom business logic before any write is committed. That logic includes: • Processing transactions – e.g., auto-generating related records, updating status fields, and posting to the correct Epicor endpoints. • Data validation – rejecting or flagging incomplete or incorrectly formatted payloads so we never pollute Epicor with bad data. • Workflow automation – triggering follow...
