Very responsive and always going above and beyond to ensure we were happy. Very knowledgeable with WordPress and Woocommerce. He was our saviour.

Great working with Simplex Software on this project. Best thing about this job was the attention to detailing, the proactive nature of finding things our team missed and sorting it out whilst communicating along the way. Already scheduled them in on the next project.
