“Kazi will not disappoint. He picks up things really fast and will make sure you can understand the C++ code when he is helping you with it. He has saved me so many times from losing my mind, and I'm so thankful that I got to meet a tutor like him!“

Kazi Sohan
OnSIP tutor
“We focused on diagnosing and resolving persistent access issues affecting the ProsperPro join site, which was intermittently returning access errors to visitors. The objective was to identify the root cause, validate the technical setup, and establish clear next steps to ensure stable site availability. The session was productive and collaborative, resulting in a clear diagnosis and corrective action plan. The issue was determined to be configuration-related rather than a platform or code defect. With propagation completing, the site is expected to stabilize without further intervention.“

“Olajide is very knowledgeable with computers. He helped me transfer my cryptocurrency from one platform to another… this is not that easy for most people and there’s a chance you can lose your wallet. Olajide made it look easy. I think it would’ve been done very quickly if I wasn’t slowing him down. He is very kind and patient.“
