Olayemi Michael

I started coding after high school for fun. Coding became passion and Java became my choice of language. I have 5 years experience developing REST APIs for e-commerce and procurement industry. My major focus include Java, Spring Boot, Databases and Rust. If I'm not coding, I write about nutrition and teach people healthy eating.

Here's what I've written (so far):
