I always loved working with Tharindu. Do you know why? He is quick to respond and professionalism at its best form. He is the first person to contact whenever I need something related website and server issues.

Tharindu is an awesome troubleshooter. He is fast. He is thorough, smart, and detailed. He knows how to resolve DirectAdmin errors, Cloudflare API conflicts, and DNS/SSL problems. If I could give him 10 stars, I would.

Great communication and got the job done in a timely manner. Would definitely recommend working with this vendor! My Sendy service was down and I couldn't resolve the problem on my own!
