About me

👋 I'm Igor, a Senior Software Engineer with over 8 years of work experience.

Technology has been a significant part of my life since pretty much always. Stimulated by my father, my first contact with programming was at age 8, back when webpages were just a lot of pretty tables and Adobe Flash (ActionScript) was all we had to make them interactive.

Fast-forward to today and I've had the priviledge of working at a diverse variety of projects and companies, ranging from seed stage startups to IPO'd enterprises. Specialized in Node.js (Typescript), React, and AWS — but always open to using new stacks.

As a Tech Lead at Z1, I pioneered the development of a digital bank, architecting and leading critical business products that reliably handled hundreds of thousands of monthly transactions using serverless technologies. I was their very first hire and worked together with the founders to build out and scale both the product and the engineering team.

At Pagar.me (a StoneCo company), I contributed to large-scale financial infrastructure, responsible for processing a massive share of Brazil's ecommerce TPV. There, I contributed to core payment processing systems as well as got the opportunity to work on prototyping new products, ranging from mobile applications to external APIs and SDKs.

I excel in remote and collaborative settings, delivering impactful solutions in software architecture, API design and infrastructure management. Passionate about innovation, I bring a unique blend of technical expertise, leadership, and business/product insights to every project.
