Top SchoolJoel Ng is a tech lead with 11 years of hands-on experience building and scaling web applications, primarily in Ruby on Rails, Go, and full-stack JavaScript.

Joel mentors junior engineers, breaks features into digestible tasks, and has research experience in cloud gaming and multimedia streaming from his NUS work, revealing a strong systems-and-performance mindset beyond typical web stacks. Based in Singapore with a Computer Science (Honours) from NUS, he excels at turning operational pain points into measurable improvements.
