I'm Igor, a fullstack engineer based in São Paulo. For 5 years I've shipped systems that handle enterprise traffic — Itaú, Unimed, Assaí, Pluxee — and MVPs that need to be live tomorrow, in Bubble.io and Logic Apps.
My sweet spot is the boundary: financial integrations (Vindi, Asaas, Celcoin, Suthub), Azure automations and Java/.NET APIs that have to talk to anything. I also co-founded ECEM, a free tutoring project that started among ETEC classmates during the pandemic and grew into multiple courses — I served as peer mentor and tutor from 2021 to early 2023.

Pet health insurance — built the IT department in Scrum and ran the SAV, claims support and BI.
Cuts of products I shipped from zero to deploy.

Brazil's first TRM platform integrated with a Digital Bank — serving 400+ agencies across 13 states (Lopes, RE/MAX, Keller Williams, among others). I worked as fullstack across the Banking and Rentals squads, with Bubble.io and custom plugins as the central piece.

Pet health insurance — I built the IT department in Scrum, ran the SAV (Bubble.io + Azure) for many enterprise partners (Itaú, Unimed, Assaí, Pluxee, among others) at Itaú-grade security, and supported the claims team. During the period, APet took 2nd place at the Reclame Aqui Award 2024 and returned as a finalist in 2025.

I co-founded ECEM in 2021, during the pandemic, with a classmate at ETEC. It started as free tutoring for friends in our class and grew into other courses — Software Development, gastronomy, business administration, tourism — with a partnership with EACH USP, which brought us logic and math content and opened up the campus to our group. I served as peer mentor and tutor until early 2023.
