    I’ve worked with this developer twice. The first Chrome Extension was built from scratch and delivered within weeks—excellent quality and communication. This second time was a much harder task, updating a complex existing extension. It stretched to about 5 months, longer than I’d planned, but he stayed responsive and saw it through.

    I hired Chethiya to fix an existing Chrome extension, and he exceeded my expectations in every way. He quickly identified the issues, implemented the necessary fixes without any assistance, and delivered a fully functional solution in record time. His expertise was evident from the start—no back-and-forth...
