My focus has been on transforming business requirements into scalable technical solutions, particularly for logistics and supply chain ERPs. One of my key achievements was leading the development of a comprehensive supply chain module that handled both local and international transportation logistics.

I also took pride in optimizing our reporting capabilities. I developed an advanced Excel export system using Apache POI that generated detailed data tables and visual charts (like pie and line charts) with conditional formatting, allowing managers to see stock trends and status updates instantly in a single file. Throughout these projects, I worked closely with my team in an Agile environment, ensuring high-quality code and timely delivery
