Leo Wang — student engineer building where algorithms, AI, and learning meet


01 — About

I’m a high-school builder at Gunn High School in Palo Alto. I like the moment a complicated system becomes legible: the clean abstraction, the working prototype, the explanation that finally makes it click.

My work sits between algorithms, applied AI, and learning tools — from a growing C++ problem archive to AI infrastructure and a block-based programming environment.

Make the idea visible. Then make it work.


02 — Selected work

Titan AI · LIVE

A free AI workspace for Gunn students: chat, homework help, web search, file attachments, and coding agents in one focused interface.

Next.js TypeScript LLM routing Postgres


USACO Solutions · PUBLIC

An indexed archive of 88 standalone C++17 solutions across USACO, Luogu, Codeforces, and CSES — organized by the reasoning behind each technique, not just by judge.

C++17 Algorithms Competitive programming


BlockCPP · PRIVATE BUILD

A Scratch-like multilingual IDE that keeps visual blocks and generated C++, Java, or Python in sync. Designed to make the first step from logic to syntax smaller.

TypeScript Compiler design Education


Realtime Chat · PRIVATE BUILD

A compact messaging system with SSE transport, read receipts, file and image transfer, profile media, and small-group conversations. Built with a self-hosted Postgres backend.

Next.js 16 SSE Postgres


03 — Current focus

ALGORITHMS   USACO / data structures / proof-driven C++
AI SYSTEMS   routing, failover, and interfaces that stay useful
