About
Hi, I'm Louis.
Taorui (Louis) Jia. I'm in the IB Diploma at Shanghai World Foreign Language Academy (WFLA), graduating in May 2027. I play competitive junior golf, I build software and AI systems, and I want to study electrical and computer engineering.
Golf first
Golf is where most of my projects start. I'm a National First-Class Athlete in golf; I won the 2025 Pittsburgh Summer Junior Open and finished T19 of 159 at the 2026 FCG Callaway World Championship (results). Tournament golf is a game of small margins, and I wanted to know exactly where mine were going. The scoring apps I used could not tell me, so I built PinTrace, and every version of it is tested in my own rounds before anyone else gets it.
What I care about when I build
- Tools I actually use. PinTrace is in my golf bag, the desk display is on my desk, and the agent tooling runs my own projects.
- Honest numbers. If there is not enough data, PinTrace says "sample too small" instead of a confident percentage. If a sensor reading is stale, the desk display says so. When I tested small AI models, I looked past the average score to the failures it hid.
- Shipping. A finished, reviewed, released thing teaches more than a perfect plan. PinTrace went through App Review, a rejection, and several releases in its first month.
How I work with AI
I write the requirements and design the system, use AI coding agents to accelerate the build, and review, test and debug every stage myself. Building with AI still needs human judgment: an AI-generated solution can look convincing while hiding architectural problems, incomplete logic and untested assumptions, so I judge results by testing rather than by appearance. Building that workflow, and the tools behind it, has been a project of its own.
What I want to study
Electrical and computer engineering, especially the systems side of AI: how agents can be built to be fast, reliable and safe in the real world. I am drawn to problems where constraints matter, such as latency, cost, compute and security, and to the question of how you measure whether an agent actually worked rather than whether it produced a good-looking answer. My projects keep pulling me there, from a sensor wired to a board to an app in a golf bag, and I want the foundations to answer those questions properly. I wrote about where that question started for me: The average said it worked. The answers said it didn't.
Beyond code and golf
- Magic Flips Club, president. I teach close-up card magic to the club's members and perform; my first school charity show was in front of 300 people.
- Training every night. Thirty minutes to an hour of strength and endurance work since grade 6, because no one required it.
- Class basketball. Part of my grade's inter-class team, currently ranked first of eight.
