I teach Math, Science and Design at Crescent Heights Academy. Grades 7 to 9.
Before this I was an engineer at Samsung R&D. I still think like one, mostly.
everything in here actually happened ↓
It's the rule in my classroom. It seemed unfair to have a website that didn't follow it. So here are the problems I've actually worked on — and the working.

Problem
Get a small aeroplane off the ground, around the circuit, and back onto the runway. Alone.
Not solved yet …
I put this first on purpose. I spend all day asking you to try things you're bad at in front of other people. It would be strange if I wasn't doing it too.

Problem
A farm has more milk than it can sell. A city is full of people who want it. There is no store, no truck, and no customers. Go.

It's called Dojhi Dairy. I built it, ran it, did the delivery-route maths myself on paper most Sundays — and earlier this year I handed it to my business partner so I could teach full time.
People ask whether that was a hard decision. Not really: I'd rather be in a classroom. But I'm glad I know exactly what it costs to build something from nothing, because that's most of what I'm actually teaching in Design.

Entry 03 · 2020–2024
Problem
Explain a system so complicated that its own engineers argue about it — to a stranger, in another country, who has never seen it.
This is also the entire job of teaching ✓
I wrote the documentation engineers around the world worked from. Nobody told me at the time that it was teacher training, but it was.

their wiring, not mine
Problem
Two robots. One ring. Three minutes. Thirty students who all want to win. What are you actually teaching?
Judgement ✓
Design covers robotics, web design and product design. The wiring in that first photo is a student's, not mine — which is exactly the point. Mine would be tidier and they'd have learned less.
Entry 05 · weekends
When I'm not teaching I'm usually up a mountain, in the rain fog, or
being aggressively greeted by somebody's dog. British Columbia does most of the
work here — I just show up and walk uphill.

Entry 06 · 2021–present
The Society of Punjabi Engineers & Technologists of BC. I've held
most every job in it — Student Activities Chair all the way to President,
and now Immediate Past President. We put on the 31st Annual Gala and started the
Scholarship Legacy Fund.

Entry 07 · 2024–2025
Deputy Returning Officer for the 2024 Cloverdale–Langley by-election, then Central Poll Supervisor for the 2025 federal election, leading a team of officers through polling day.
Somebody wrote my name on a badge in marker and made me responsible for a room where people vote. I've kept the badge.
every year
Entry 08 · 2018–present
I've helped run Sikh Nation's annual blood donation camps since 2018 — and I roll up my own sleeve at them too.
It's the most straightforward useful thing I know how to do. Blood donation takes about an hour, it costs nothing, and somebody you will never meet gets to carry on. Most of my students aren't old enough yet — but they're closer than they think, and I'd like them to know it's there when they are.

I did not choose the antlers.
but I did keep them on all day
For parents, colleagues and anyone who needs the formal version.
Parents and colleagues: the fastest way to reach me about anything school-related is through the Crescent Heights Academy office.
Everyone else — engineering, community work, or aviation — LinkedIn is best.
