Accountant

Summary
I’m an accountant with hands-on experience at NEXACC, where I improved financial accuracy by managing accounts receivable and payable and setting up stronger internal controls to reduce fraud risk. I’m comfortable working with QuickBooks Online,Odoo and advanced Excel, and I enjoy using numbers to tell a clear story. Earlier, as a training support associate with Inkomoko, I helped equip more than 6000 refugees across refugee camps in Rwanda with practical business skills like financial literacy, an experience that strengthened my ability to work with people and solve problems collaboratively.
