Hi,
As a seasoned Full Stack developer with over 9 years of experience, mostly working on e-commerce projects, I am confident that I can effectively solve the issues you're facing with the Magento admin panel. Having completed more than 550 successful projects, I've come to understand the nuances and complexities of platforms like Magento and well-equipped to handle bug fixing tasks.
My expertise in PHP and MySQL is especially relevant here since Magento is built using these technologies. Not only have I tackled similar challenges in the past, but my problem-solving approach and keen attention to detail have resulted in a high accuracy rate of 98% to 100%. This means I will thoroughly investigate and rectify both the login error after email confirmation as well as the missing sales orders from your system.
Furthermore, my proficiency with APIs adds another layer of value to my service offering. If necessary, I can use this skill set to scrutinize third-party integrations or whichever factors might be contributing to these bugs. Overall, my primary goal is your utmost satisfaction through timely solutions and lasting results. Please do not hesitate to reach out.
