At L-Mobile Tunisia, I led the design and implementation of an end-to-end integration between a sales application and HubSpot, including the API layer, data mapping, validation, and error handling.
I also designed and built a one-time migration tool from SQL Server to HubSpot. I used T-SQL to extract and shape data, then developed a C# application to apply transformation rules gathered from the internal sales and marketing team.
I own production deployments across customer environments and handle escalated third-level support. I also review code and guide developers through design decisions and debugging.
