Function

I turn challenging software infrastructure into powerful products.

I'm a founder and product manager. I specialize in building AI software products from concept to market adoption. I built ByteNite in San Francisco, a serverless compute platform that raised $1.2M and turned GPU scheduling headaches into a well-loved developer product. My background is in mathematics, coding, and statistics, but what drives me is owning technically challenging infrastructure and making functional and sleek software experiences out of it.

Areas of Expertise

Where I create the most impact

From zero-to-one product strategy to technical leadership: here's how I think and what I build.

Education

Foundations

Five years of mathematics and data science at Università degli Studi di Milano. The training that taught me how to break a problem down and rebuild it from first principles.

MSc GPA 30/30

MSc in Data Science & Economics, Università degli Studi di Milano

I attended a Master's degree course in Data Science and Economics, scoring a perfect GPA of 30/30. Dropped out before the thesis to pursue my startup. Coursework covered Machine Learning, Statistical Learning, Econometrics, and Programming. Capstone project: “Decomposing and Clustering the EU Business Economy”, applying dimensionality reduction and unsupervised clustering to large-scale macroeconomic datasets to identify structural patterns across industries.

BSc Scholarship recipient

BSc in Mathematics, Università degli Studi di Milano

Undergraduate degree in Mathematics (GPA: 108/110) and a merit scholarship. This three-year degree (one of the University's hardest, with a 60% dropout rate) was a crucible for rigorous thinking and problem-solving. With a focus on deep theoretical foundations (Algebra, Calculus, Geometry) and applied subjects (Combinatorics, Physics, Optimization), it trained my way of approaching complex problems: work upwards from hypotheses and downwards ad absurdum, until you meet truth in the middle.

Experience & Projects

What I've built

Four years of company-building, plus my side projects. The work that best shows how I think when given a blank page.

ByteNite Founder & CEO · 2021–Present

ByteNite: Serverless AI Compute Platform

I founded ByteNite in 2021: a serverless compute platform that turns GPU infrastructure into a clean developer experience for AI inference, web scraping, and video workloads. I raised $1.2M, joined Techstars San Francisco (Fall 2024, top <1% of applicants), and filed a US/EU patent on high-throughput distributed computing.

As technical founder I owned the full stack: product, engineering, GTM, hiring, and investor communication, turning hard infrastructure into something developers actually wanted to use.

Feeder Personal Project · 2026

Feeder: AI News Aggregator

Feeder is a solo project I built in 2026: an AI news aggregator that scrapes, ranks, and summarizes articles from across the open web. A QWEN-3 planner with cached DSL replays handles extraction, a BGE-embedding recommender with implicit feedback and MMR diversification handles ranking, and a vLLM-served Qwen summarizer with xgrammar produces reliable structured outputs.

I architected and shipped it with Claude Code and the gstack toolchain, taking infrastructure decisions and making each trade-off calls, and modeled the unit economics (CAC by channel, gross margin, payback) of a monetizable version.

disCOVIDer19 Research · Publication · 2020

disCOVIDer19: COVID-19 Data Analysis App and Paper

In 2020, I co-authored disCOVIDer19, an app and paper providing data-driven insight into the COVID-19 pandemic. It analyzed epidemiological datasets and built visualizations of transmission patterns and regional dynamics, and was recognized by the Italian Society of Statistics (SIS).

About Me

Mathematician, builder, pianist.

I grew up in Bergamo, Italy with two seemingly unrelated obsessions: mathematics and the piano. I pursued both seriously. A BSc in mathematics then an MSc in data science, alongside fifteen years of classical piano training and performance. What I didn't realize at the time was that both were teaching me the same thing: how to break a complex system into its essential parts, and how to make something technically demanding feel natural.

That instinct brought me to San Francisco in 2022, where I founded ByteNite, a cloud infrastructure company built around the idea that powerful AI compute shouldn't require a PhD to configure. We went through Techstars, raised $1.2M, filed a patent, and I spent five years learning what it really means to build from zero: the product, the team, the go-to-market, and everything in between.

I work best at the intersection of technical depth and human clarity. The most elegant products aren't the ones with the most features: they're the ones where every complexity has been absorbed so their core value, be it to save time, increase productivity, or to entertain, is immediately accessible to the user.
