Aditya Katre

I build AI systems, keep Linux servers alive under attack, play tenor sax, and climb things.

Senior at Del Norte High School in San Diego. Researcher at SDSU's Data Science Lab. Eagle Scout. I like being the least experienced person in the room, because that's usually where I learn the most.

The route

Eight waypoints, one climb

The site is laid out like the trail up Mt. San Jacinto, which is where the idea for Scrapp started. Each section is a waypoint. The counter in the corner shows how far up you are.

In the news

"We saw our school's recycling bins empty and the trash cans almost full. It's not that our peers don't care, they are just not putting in the mental effort." Me, in The San Diego Union-Tribune, March 2026, on why we built Scrapp

Why a trail

A hike is a lot of small steps

On a Troop 685 backpacking trip, I slipped on icy granite near the summit of Mt. San Jacinto and caught myself with my trekking poles. The next day I led ten scouts on a cleanup and we picked up bottle caps and wrappers the whole way. On the same trip, nobody in my patrol knew how to throw away an empty propane canister.

That canister is the reason Scrapp exists. It also explains most of what is on this site. I usually get somewhere by taking a lot of small steps, and I want to make those steps easier for other people too. That might mean teaching a younger scout, building practice servers for my cyber team, or writing software that tells you which bin to use.
