I'm a junior at Saint Joseph Notre Dame in Alameda, California. Right now that means an AI phonics tutor designed around a controlled reading study, a web app that measures real breast biopsy slides, and a tool for the environmental side of nuclear siting that I've been taking to the people who would use it. I'm also class president, a national debate competitor, and part of TKS San Francisco this year.
Languages: English, Mandarin
Off the clock: Calisthenics, Swimming, Piano, Cooking, Violin (played recitals)
4.25 GPA, 4.0 unweighted.
All A's, with a 5 on the AP Physics 1 exam. Academic Achievement Awards in Physics and Religion. 4.57 GPA, 4.0 unweighted.
Plus four college classes at College of Alameda: Physics 4A and Calculus II this fall, Physics 4B and Calculus III in the spring. On track for a 4.86 GPA, 4.0 unweighted.
College courses I'm taking alongside my junior year at SJND.
SJND's merit award for academics and leadership, all four years of high school.
Seven projects: what's running, what's in the works, and what I stopped, with the reason.
Read a breast biopsy the way the model does.
Pick a real breast fine-needle-aspirate slide. The server outlines every cell nucleus, measures the eight features lab software extracts, runs a model trained on 569 real patients, and explains the call as a count out of 100 patients, not a percentage.

What I found: Every number has to explain itself. Version one showed eight numbers and a slider, and nobody in the room, including me, could say what a "worst radius of 12.2" meant. So I moved measurement to the server and made every number answer three questions: what is it, what is normal, and what did it do to the result. Nine versions in three days.

A ladder app for my school's chess club.
Club members sign in with a school email, play rated games, and climb an Elo ladder. Games can be imported straight from Chess.com.
What I found: Test the math before the screens. A club ladder lives or dies on its ratings being right, so the Elo code got its own unit tests before any screen existed, and the ladder was built on top of it.

The multi-agent setup I build everything else with.
One planner writes contracts first, several builder agents code against them in parallel, and a separate verifier checks the result in a real browser before I see it. OncoScan and this site were both built on it.
What I found: Contracts before code. Fixing every exported name, prop, and section id before any agent writes a line is what let four builders work at once with zero integration fixes. The rules that matter are enforced by hooks and tests, not by the prompt, because prompts don't hold.
An AI phonics tutor that hears which sound you missed.
A tutor for kids learning to decode. It shows a word, listens to the child read it aloud, scores every sound separately, and coaches the exact sound they missed. It is the loop a good reading tutor runs, automated.
What I found: Judge the sound, not the word. At the word level, "sip" and "ship" score five points apart and both pass. At the phoneme level they score 100 and 45. And a correct word-final /t/ or /p/ scores 54 to 78 while held sounds like /s/ score 87 to 100, so a single pass mark can never be fair. Thresholds have to be set per class of sound.
Closing the environmental gap in nuclear siting.
AI data centers need more power than the grid can add, and much of the industry is looking at nuclear. Siteline started as a tracker for candidate sites. Customer discovery pointed it at a newer problem: as the NRC narrows its reviews to radiation, the environmental due diligence outside the fence (waterways, wildlife habitat, water tables) has no clear owner. Siteline now aims to pull those public environmental layers together for each candidate site, so whoever ends up owning the review starts from a complete base.
What I found: The first customer I designed for didn't exist. Two weeks of customer discovery showed that site screening is already a free government tool and that developers do siting in-house. Then a call with GAIN, the Department of Energy's nuclear innovation program at Idaho National Laboratory, turned up the real gap: with the NRC drawing its line at radiation, nobody clearly owns the environmental review. That gap is what Siteline is for now.
Photos in, a ready-to-post marketplace listing out.
Snap a few photos of something you want to sell and SellSnap reads the labels, matches the product, and drafts the title, description, and a price for Craigslist or Facebook Marketplace.
What I found: The price is the whole product. I moved it from OpenAI to Gemini with search grounding, then built a benchmark that scores its price estimates against real eBay sold prices. That's how I learned pricing was the weak point: with no ground truth, the model was guessing. I paused it rather than pretend otherwise.

An early warning for breaking API changes.
Watches vendors' changelogs and flags changes that would break the apps built on them.
What I found: Know when to stop. I built the watcher, then did the market research: the best-known tool in the space died of onboarding friction, platforms like Shopify now publish their own API health reports, and three business days of outreach to agencies got no replies. So I stopped.
The island version has six small games built on these projects.
Where I do science, from a 7th grade yeast experiment to a week at a national lab and the study behind readtutor.
1st in my school, 3rd in the district, and 4th in the county.
Five days with working physicists on dark matter, dark energy, the cosmic microwave background, and neutrinos. We toured the Advanced Light Source and saw a focal-plane petal from DESI, the instrument building the largest 3D map of the universe.
Real physics is mostly stumbling, and the stumbling is what gets you closer.

When QuarkNet's NSF funding wasn't renewed, I wrote to Senators Padilla and Schiff and to my House representative asking them to restore it. For more than 25 years it has been one of the few ways a high school student can get into real physics.
Why there is so little published evidence on AI tutors for early English decoding, and what a credible study would need.
The benchmark is the d = 0.57 effect of one-to-one phonics tutoring. The design is a multiple-baseline single-case study across three phonics skills, where each child is their own control, measured three times a week with DIBELS 8 Nonsense Word Fluency. It goes to a review board before any child uses it.
Nurse humor with hidden cat jokes, made to order.
My print-on-demand store for nurses who own cats. I design the line around one orange tabby across tees, crewnecks, mugs, and totes, Printify prints and ships each order, and I make the marketing myself: storybook-style animated shorts for TikTok.

A fast, clean site for your salon or restaurant, kept current every month.
I build the site once, then keep it up to date on a monthly Care Plan: menu and price changes, hours, photos, and hosting. I've pitched five Alameda businesses in person. This portfolio is the sample.

Elected sophomore year and on the school-wide student council. We won one of the two biggest rallies of the year, and stayed ahead of the seniors longer than any sophomore class before us.
Elected in spring 2026.
Starting the school's math competition club and bringing contests like the AMC and Math Kangaroo to SJND. Math Kangaroo is approved for its first year.
I co-run the club and built its ladder app. I started my middle school's lunch chess club in 7th grade.
An economics competition club. We also mentor junior high students in personal finance.
Helped run orientation day for the incoming freshman class.
Competed in Richmond, Virginia, on Team San Fran Bay Purple, a five-person Bay Area team.
At my second Congress tournament.
Lead strategist. I designed the whole robot and I'm building it: a floor intake, a single-file collector, a diverter that picks the exit, a twin-belt launcher with a spring-floated gap for two ball sizes, and a vertical-lift placer, all inside the 8 motor and 8 servo limit.
With the SJND robotics team.
Five games, five wins. Online, I peaked at 1799 on Chess.com.

Advanced to nationals. Our team placed 2nd overall in the region.
Reached the top 300 of the US Ranked leaderboard, peaking at #275.
Ran varsity as a freshman, with a 5:17 mile. Now I swim and do calisthenics.
A ten-month program for young builders working on emerging tech in AI, biotech, and energy. Week one was a 30-minute pitch on failing water infrastructure in Kiambu County, Kenya. Week two was OncoScan.
Thirty minutes is nowhere near enough to become an expert, and exactly enough to find the one fact that makes someone care.

The official US youth climate conference under YOUNGO, the UN climate body's youth constituency. I'm one of about 125 delegates writing the US National Youth Statement that goes to COP.
My ask: Legal and financial on-ramps for young founders. A teenager can build a climate tool in an afternoon but can't open a business account or take payments without an adult. The technology says yes to young builders and the paperwork says no.
I'm going to listen and find out where I'm wrong about nuclear.

The youth membership of the United Nations Association of the USA.
A summer of Mandarin study in Shanghai on a CIEE merit scholarship.
Ten days in San Cristóbal with my church group. We framed and roofed a two-bedroom house for a family whose old one had a dirt floor and a leaking sheet-steel roof, replaced their open-fire kitchen with a stove that vents outside, and ran Vacation Bible School for the kids.
On the last day we handed over the keys.
