Hi, I’m Johanan S. A.

Mechanical Engineer with a passion for technology and innovation. I build things, sometimes mechanical, sometimes digital but always practical.

About Me

Mechanical engineering student with a weird mix of interests. Started with CAD and SolidWorks, then got pulled into web development and ended up building full-stack apps for startups and local businesses. Somewhere along the way, I picked up ML and IoT too. I guess I'm just curious about how things work and like building solutions across different domains.
