Lumis
I started Lumis as a project to learn how to design and build an iOS
app.
Around this time, many of my friends were struggling to find jobs. I was
also mentoring students who didn't know which careers to pursue or where
to start their research.
I discovered
O*NET ↗, a
comprehensive government database with detailed career information on
thousands of jobs. The problem was that no one I talked to had heard of
it, and the interface wasn't exactly user-friendly.
The challenge was connecting loosely defined interests like "I enjoy
helping people" to structured career data full of technical jargon.
Keyword search wouldn't work here, but LLMs could bridge that gap by
understanding intent and surfacing careers someone might never think to
directly search for.
Students could input their interests and goals, then the app matches
them to relevant O*NET careers through semantic search.
From there, they can chat with specialized LLMs grounded with
corresponding career context to dive deeper into different fields.
I eventually sunset the project due to maintenance time and hosting
costs, but it achieved its goal as a learning experience.
