about me 👨🏻‍💻

$ pwd san francisco

I’m Gian (pronounced /ɡi'ʔan/, same as 'jan' in january), short for Gianluca.

I’ve been at Replit for the last couple of years, where I’ve been building many things. Among them, I designed and developed Replit’s growth infrastructure, built our highest converting acquisition channel (100 Days of Code), and architected foundational data infrastructure to train state-of-the-art AI models.

These days I spend most of my time contributing to our AI research team, where I worked on the SOTA model Code Repair 7B, and our new embeddings layer.

Before Replit, I founded Uniwhere, a mobile app that uses data to help college students make better decision for their career. It automatically parsed students’ academic records through distributed data scraping, and matched them with an ontology of the job market to suggest users the best career paths.

Uniwhere grew to over 600k users organically, a third of the market where we were active, with 0 marketing budget. It’s been included among the top 100 startups in Berlin and has been featured in several international media outlets, from SkyNews24 to The Huffington Post. After raising two venture rounds, in late 2021 we sold it.

I love to learn and I love to tell the world about what I learn. You can find me fairly often as a speaker at meetups and conferences. In 2019, one of my talks was showcased by Google as one of their top 40 tech talks of the year worldwide.

In 2017, I was awarded Italian of the Year by the Italian Embassy in Germany. During my college years, I founded the then biggest student-led theatre company in Italy. In 2011, I was given the High School Excellence award by the Italian Ministry of Education.

I’m also publishing a private newsletter, that I send only when I feel like I have something to add to the conversation. I read every reply. You can join it here:
