About me, but longer

The work, the side quests, the things I do when I'm not staring at a terminal.

Work

Abstra

Aug 2024 — Present

Software Engineering Intern

YC S21 startup that lets companies automate business processes without writing code. I work across the whole stack — API, frontend, integrations — and helped 4x MRR without the team growing proportionally. Helped build an internal RPA agent and significantly improved SmartChat — the core feature where non-technical users talk to an AI to build their automation flows.

The Six Club

Feb — Jun 2025

CTO

Startup that connects strangers to foster real relationships. Built the matchmaking algorithm that analyzes user profiles to create high-compatibility tables — 50+ people weekly. Landed partnerships with XP Investimentos and The Dev Conference (200+ attendees). Also built the app for the full user experience.

BTG Pactual

Jan 2025

Summer Intern

Biggest investment bank in Latin America. Designed and implemented 12 new automated alerts for fund sales risk monitoring (previously only 4 existed). Saved 4 hours/week per employee.

Research

Opinion Dynamics in Social Networks

Inteli — Advisor: Prof. Dr. Henrique Paiva — Dec 2025

How do ideas spread through networks? I applied epidemiological models (SIR/SIS) and agent-based simulation to study how opinions and information propagate through different social network topologies. Turns out, modelling virality is literally like modelling a virus.

Other stuff I do

Inteli Entrepreneurship League

Ran this as president for a year. Organized one of the biggest student-led entrepreneurship events in Brazil — 200+ people, R$30k in sponsorships, panels with founders and VCs, all organized by students. Also created Steps, a training program that helped launch 20+ startups, and founded the Club of 5, uniting the top entrepreneurship leagues from ITA, FGV, Insper, PoliUSP, and Inteli. Oh, and built the website too.

Teaching

Was a math TA at Inteli — helped run 6 classes per semester and taught 3 myself. Before that, English TA for a year. Also taught Python to 50+ young people in vulnerable communities through Code Club. Because everyone should get a shot at this.

Chess

Competed as a kid. Took it seriously, tournaments, trophies, the whole thing. Nowadays I play for fun and would honestly probably lose to my 10-year-old self.

Music

I play bass and guitar. Sometimes I DJ. None of this is professional and that's the whole point.

Skydiving

Yes, I jumped out of a plane. Would do it again.

Reading

I read a lot. Mostly non-fiction, business, and whatever rabbit hole I fell into that week. Open to recommendations.

Medals & trophies

I was that kid who did every olympiad, mostly math but also science, history, physics. Got a gold in the Goiás State Math Olympiad at 12, which shaped a lot of what came after.

More recently I've been doing hackathons instead — 2nd place at Sonda Safe City, 4th at Modular Carnival, and got flagged as one of CAPES' best performances in 2024.
