5-star rated on Codementor across 2,500+ sessions and 1,250+ reviews.
"Thomas has been instrumental in my development as a web developer. In particular his knowledge of Node, front-end frameworks, and JavaScript in general, as well as a variety of web development concepts, has really helped me to rapidly build up my skills and understanding. He has been very thorough in code reviews, is quick to understand the purpose and structure of my apps, and evaluate them based on his knowledge of best-practice. I look forward to more sessions with him!"
"Thomas is absolutely BRILLIANT! I spent more than 30 hours on a feature, which 30 hours didn't even get me near as far as I hoped... Then when I was at my wits end with fighting this build out. Thomas was able to assist me in a matter of 2 hours, and that was including a little fancy styling... I absolutely RECOMMEND THOMAS!!! THANKS THOMAS!!"
"This guy is the best developer I have ever encountered in my entire career, he understands everything in seconds, and guides you through the solution in the clearest way possible, definitively hire him right now."
