Background

My story began on the other side of the table. As a former accountant, I know first-hand the frustration of waiting for data and time-consuming repetitive tasks.

This experience drove me to programming – first for myself, later for colleagues. Now, with 25 years of experience, I understand exactly what the shop floor needs and deliver solutions that really work.

I am also proud of the financial successes I achieved for clients – such as securing last minute grants or getting significant refunds.

Results that really count.
