Hello — I'm
Welcome back,
Jason Lin
I'm a medical student who loves to build things that help people understand how they learn, think, and work.
Explore this site to discover free tools, tiny experiments, and practical stuff I've built — made for learning, curiosity, and keeping things lightweight.
Everywhere I've been & eaten
One map of every place I've traveled and every spot I've eaten — flights, trips, and restaurants on a single spinning globe. Drag to rotate.
Who I am
Full-time medical student, part-time educator, ex-entrepreneur, and full-time builder of side projects. I spend a lot of time thinking about how people learn, how systems work, and how everyday life can be measured, understood, and improved.
Outside of work, I’m usually playing arcade games, on the badminton court, solving crosswords, trying a new restaurant, or obsessing over another unnecessary side project.
I’ve always had an obsessive curiosity across languages, math, technology, medicine, and education. I’m driven by a constant desire to upskill, stay broadly well-read, and build things that meaningfully improve how people learn and live.
What I'm into
Side projects and rabbit holes across the site — hover a tile to peek inside.
