Legacy ERP to monday.com Sync -- 2

Job ID: 39837671

Budget: $15 – $25 USD

I need a rock-solid, two-way bridge between our Windows-based Tradesoft ERP (Sybase/SQL Server on .NET) and monday.com. The integration must push and pull customer records and order-processing data in real time, while also feeding a reporting layer on the ERP side. Inventory isn’t in scope right now, so the focus stays on those three data domains.

Because the ERP exposes both direct SQL access and a small .NET API surface, and monday.com offers a GraphQL/REST API, I expect the solution to sit as a lightweight Windows service or cloud function that can:

• Detect and propagate inserts, updates, and deletes within seconds
• Resolve conflicts gracefully, preserving the system of record flag we set per table
• Log every transaction for audit, with retry logic and alerting

Deliverables
• Technical design and data-mapping document
• Source code (C# preferred) with clear comments and unit tests
• Deployment script or container image plus a short run-book
• Final hand-off session and knowledge-transfer notes

Reliability and maintainability matter more than speed of delivery, so the schedule is flexible. If you have proven experience wrangling Sybase or SQL Server data, .NET integration layers, and SaaS APIs like monday.com, I’d love to see how you would approach this.
