Iago Guimarães

@iagoguimares

I build scalable full-stack platforms and AI automation with Angular, React, and Node.js.

What I'm looking for

I'm open to remote and international opportunities where I can lead full-stack delivery, modernize architecture, build reliable products, and collaborate with diverse distributed teams.

I've led full-stack engineering at Avalara Brasil, shaping architecture for a global data-ingestion platform built with React and Node.js and a regional customer portal using .NET and Angular.

I engineered an AI-driven field-mapping feature that reduced manual data-entry processing from five minutes to under a second. I also modernized a legacy monolith into a layered backend architecture that lowered maintenance overhead and accelerated feature delivery.

I built Avalara's Cypress functional testing pipeline from scratch, improving reliability and reducing bugs reaching production. My work has included technical leadership with multinational product and project stakeholders in remote, distributed teams.

Earlier at CI&T, I delivered the Moto Maker customization platform for Motorola and built Angular experiences for brands including Coca-Cola, Rede, NSK, Siemens, Quala, and Itaú. I bring more than 10 years of experience across Angular, React, Node.js, Java, Ruby, cloud data stores, and modern delivery practices.
