Oluwajolasun Jaiyesimi

Fullstack Developer

I craft solutions that meet technical demands and deliver engaging user experiences, by seamlessly integrating front-end and back-end technologies to create robust, scalable applications with added expertise in ML/AI powered applications and workflows.

Background

A Masters Degree Software Engineering graduate from the University of Calgary. My tech journey began with a strong interest in web development, after taking a computer science course at loughborough college

I built my first static website by memorizing HTML tags and basic CSS styles using notepad, and has lead me to work with cutting-edge technologies such as React, Tailwind CSS, React Native, Express, SpringBoot, AWS, SQL and NoSQL Databases.

I thrive in dynamic environments where I can leverage my skills to solve complex problems and contribute to impactful projects. My experience spans from designing intuitive user interfaces to optimizing back-end functionality, ensuring a well-rounded approach to full-stack development.

When I’m not coding, you might find me playing video games, watching anime, lifting heavy weight, exploring the latest tech trends, or diving into new tools and frameworks.
