About Me

John Elvin
Endrenal

I'm a Computer Engineering student who sees the world through math and technology — because that's exactly what the world is made of right now.

I love problem-solving: breaking down something complex, finding its parts, and solving them one by one. Teaching that process — the way I actually think through problems — is what I care about most.

I'm an aspiring Software Engineer and Lecturer. Outside the classroom, you'll find me in hackathons, math competitions, and grinding on Codewars.

Why Me

Not just another tutor.

I tutor because I love the moment a concept clicks. Here's what I bring to every session.

I Actually Do This Stuff

I'm not teaching from a textbook — I compete in math competitions, hack on coding problems, and build real projects. You get first-hand knowledge.

Concept-First Teaching

I break every topic down to its why before its how. No rote memorisation. You'll understand the idea so deeply, you could rediscover it yourself.

Engineered for Clarity

Complex topics divided into small, solvable pieces — the same approach I use in competitions and real-world engineering problems.

Competitive Mindset

Hackathons, math competitions, Codewars — I bring real competitive experience and pressure-tested thinking to every session.

Flexible Formats

Solo sessions for focused deep dives, or group sessions if you and your classmates want to learn together and split the cost.

Keeps Up with the World

From fundamentals to AI and modern web dev — I teach what's actually relevant in tech right now.
