Caleb Kalejaiye
Software engineer
Hi there, I’m Caleb also known as Rapto. I’m a fullstack webengineer interested in building smooth and seamless web experiences. While I focus on the web, i’m also interested in the bigger picture of how app development works.
I enjoy building dev tools as there's something satisfying about making everyone's workflow smoother. Whenever I see a problem that could save another developer time or frustration, I try to build my solution into a tool.
On the side, i am also interested in ai/ml engineering. I try to learn more about the ai ecosystem and sometimes build small projects around it.
