À propos de moi
I build structured Excel systems that are practical and easy to use.
I designed an accounting ledger system for OAK Business School using Chart of Accounts, Journal, and Ledger to manage financial data properly.
I help turn messy data into clear, organized, and functional systems for real use.
I also use basic SQL and Python to support data handling and improve workflow when needed.
If you need something accurate, structured, and reliable, I’m ready to help.
