Had a great experience working with Alex. He is talented at creating the A/B tests and needed little to no direction after the initial scope of work was presented. I will be working with Alex for a long-term arrangement! I wouldn't hesitate to work with him. You'll be in good hands.

It was great working with Alex again. Was a potentially complex sitewide test but Alex developed it perfectly with no major complications or bugs. His communication and speed of delivery is top notch.

Alex is a real pro at what he does. I was impressed at not just his code expertise, but his willingness to see through, communicate and solve complex challenges that we faced during development. Thanks to him, we were able to launch a fairly complex test successfully. I look forward to working with him again!
