Custom WooCommerce Payment Plug-in/Extension for Wordpress site
"Our company is thankful to have found John on Upwork and working with him has been an extremely rewarding experience to help scale our business. I can confidently say that John is the most reliable and honest person I have worked with on Upwork, and his work ethic, expertise and integrity was invaluable for all tasks that we unexpectedly assigned to him. John assisted in recruiting, onboarding and leading a development team to complete major integrations with payment extensions and large institutions. In addition he assisted with creating polices, procedures and standards for our company pursuant to PCI DSS and served as a lead in our first PCI Level 1 remote-assessment. We plan to continue working with John in the future as he has a creative method of tackling solutions that require an extremely dedicated focus with reliability and fairness. At the beginning we only wanted him to assist with developing a custom payment integration solution but after working with him it became clear that he had potential to assist us with other major tasks to complete. If you’re fortunate to hire John, take your opportunity and grab it. People like him are very rare to find and you wont regret working with him."
