Hi there! I’m Kevin Ge

About

I'm an electrical engineering student at the University of Waterloo. I like working on projects that eliminate as many repetitive tasks as possible. As an active (ab)user of vibecoding, I love the capabilities that it gives to the average person, especially if you're using it right! I for one am very excited to see where the AI space moves from here. I love music (90's hip-hop, c-pop, and jazz specifically) and am a semi-washed pianist, clarinetist, and drummer. I believe that doing things is the best lesson that anyone can learn. If there's an idea, you should just go and pursue it! Turn it into reality, and don't look back. Most people that judge are usually too lazy to even try. You got this :)!

Hot take: People should be friendly to AI - what if it gains consciousness one day? ;)

Tim Hortons AI

Next.js·TypeScript·OpenAI·RAG

An AI customer service agent that takes action on the customer's behalf (lookup account, check rewards balance, restore points, issue a perk) in Tim Hortons brand voice. Hand-built agent loop and streaming protocol, custom RAG over a curated FAQ corpus, and an LLM-as-judge eval harness.

  • Hand-written agent loop and NDJSON streaming protocol; no LangChain, no Pinecone, no Vercel AI SDK
  • Tool calls for live customer actions: account lookup, rewards balance, points restoration, perk issuance
  • Cosine-similarity RAG over 25 hand-curated FAQ entries using text-embedding-3-small
  • LLM-as-judge eval harness across 10 scripted scenarios; 100% pass rate on the gpt-4o configuration
