Software Engineer, ERP and Integrations

CT PRODUCTS • Part-time

Aug 2025 - Present • 1 yr 2 mos

I joined CT Products in 2025 as a full stack developer on ISOLAT ERP. I started by building the HCM module with employee management. I then took on the sales and purchase modules and the accounts ledger. Alongside these modules, I built the integrations that connect the ERP to the outside world: FBR and PRA tax systems, POS, Hikvision devices, e-commerce stores, Elasticsearch search and ZATCA e-invoicing. Achievements (bullets): Built the HCM module from scratch, including employee management Developed the sales and purchase modules and the accounts ledger Integrated FBR and PRA tax filing directly into the ERP Connected POS systems and Hikvision hardware to the ERP Synced e-commerce stores with ERP inventory and orders Added Elasticsearch to make searching large ERP data fast Implemented ZATCA e-invoicing so the ERP meets Saudi tax rules Delivered production features in DotNet, C# and SQL Server used by real businesses
