About Me

Looking to build something great? You are in the right place!

Lucas Germinari

Who am I?

Hi, I'm Lucas. I love building things that work in the real world and solve real problems. I graduated from Indiana University with a B.S. in Computer Science (AI specialization) and High Distinction. Professionally and academically, I've:

I care just as much about the business behind the build:

  • Collaborated with Anthropic as a Claude Builder Ambassador to launch the Claude Builder Club, now with 600+ members
  • Co-founded Hubble (later renamed Bobby) — a conversational AI platform that had 300+ beta users — and Goliath, a legal tech startup that is currently in pilot with law firms in Indiana
  • Provided freelance services spanning different kinds of software systems from requirements gathering to launch

I'm open to freelance work, consulting, and participating in ventures — if you have an idea to bring to life or want a partner to build with, let's talk.

Hear From Others

Collaboration is at the heart of my work — here’s what others have to say.

A Mentor Who Inspires

I met Lucas when I joined Entropic, which at the time had been recently founded by him. My experience with him, from collaborating on programming projects to being mentored, showed that his skills stand out in many ways.

He combines technical expertise with a strong sense of responsibility, always ensuring projects are organized and moving forward. I think that his leadership style really plays a role in these situations, especially his ability to take a group of people and organize them into a team that gets things done.

Lucas’s mentorship was both patient and inspiring, and his ability to balance excellence with approachability made him an invaluable leader in the community.
