Caleb Kalejaiye

Software engineer

Hi there, I’m Caleb. 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 and smart contracts works.

I enjoy building dev tools —there's something satisfying about making everyone's workflow smoother. Whenever I solve 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.
