I like to
build stuff.

Junior at Menlo School. I start companies, build apps and machines, and finish what I start. Right now I'm building a stealth startup.

Things I've built.

Apps, hardware and machines I've built or am building now.

In development

Splatter

2026 · iPhone app

The family cookbook. Snap a photo of a stained, handwritten recipe card and Splatter turns it into a clean recipe your whole family can share, scale and cook from, with the original card kept alongside it.

Elsewhere

2026 · Hardware + iOS app

Be anywhere. Snap the Elsewhere puck onto the back of your iPhone with MagSafe and your phone's location is yours to choose. Drop a pin to be there instantly, or pick a start and an end and glide along a real route at any speed. It all runs from a simple app on your phone, with no laptop or cables, on its own battery that charges over USB-C. Tap Stop and you're back on real GPS.

PRISM

2026 · Hardware + software

Wave a hand to pause, skip or turn it up. A wooden boombox I designed and built by hand. A webcam reads hand gestures, and a 7-inch touchscreen shows lyrics synced to the song alongside the album art. Two 3-inch drivers each sit in their own sealed chamber on a 20 W per channel amp, so the bass stays punchy and clean at room-filling volume. It runs on a Raspberry Pi with Bluetooth and AirPlay 2, five screen themes and a rechargeable battery, all inside a laser-cut case with hand-fitted finger joints.

Robo-Hoop

2026 · ME/EE final project

A full-size arcade basketball game built with a partner for our mechanical and electrical engineering final at Menlo. The hoop rides back and forth on rails so every shot is a moving target, with a net to catch misses and a ramp that rolls the ball back to you.

Kinetic Pinwheel

2025 · Mechanical engineering

Two laser-cut flywheels spin in opposite directions on a 120 RPM motor to create an optical illusion, backlit by LEDs behind a diffuser. I modeled every part in CAD, dado-cut the wood box, wired the electronics and built a magnetic back panel over nine build days.

Journey · 2021 → now

From robotics club to founder.

Eight stops so far, from the Hillview robotics team to the company I'm building now.

Aug 2021 – Jun 2024

Hillview Middle School

Robotics team, JV tennis and the Buddy program. Robotics is where I first wrote C++ and got hooked on making things work.

Middle school
Jan 2023 – now

Kids Ministry Leader

At New Community Church in Menlo Park I run interactive learning stations and lead small groups for younger kids.

Volunteering
Aug 2024

Menlo School

Started high school. Football, lacrosse, soccer and golf on the field. Python and C in the classroom.

High school
Apr 2025 – early 2026

Zellen Design

A friend and I started Zellen Design, a company building websites for local businesses like landscapers and plumbers. We wrote our own algorithm and app to find businesses that needed a site and connect with them, then designed and built the sites ourselves. Along the way we learned cold calling, pricing, closing deals and working as a team. We wrapped it up in early 2026 to start on something new.

Co-founder
May 2025 – now

Lifeguard & camp counselor

Summers at Menlo Circus Club in Atherton. Keeping the pool safe, handling emergencies, and running the day for a crew of campers.

Menlo Circus Club
Jun 2026

Google AI certificates

Earned the Google AI Professional Certificate and AI for App Building, covering prompt engineering and agentic workflows. Eleven certifications so far.

Certifications
Jun 2026 – now

Stealth startup

Working on something new that I can't talk about yet.

Right now

Junior year

Juggling school and sports while I build my startup, ship Splatter and keep learning how businesses actually grow.

Class of 2028
Sports · Five and counting

On the field.

Football, lacrosse, soccer and golf at Menlo. Tennis is where it started, back at Hillview.

Into

What I'm into.

The three things I keep coming back to, in school and outside it.

Business

How companies grow

How companies start, find customers and make money. Zellen Design taught me cold calling, pricing and closing deals. I want to understand the whole picture, not just the product.

Engineering

How things work

Robotics in middle school, Python and C now, and CAD, wiring and woodwork in Menlo's engineering classes. I like knowing how things work, from a line of code to a jet engine.
