Full Stack Engineer at ZeroRisk building an AI-powered vendor compliance platform with autonomous assessments across major standards.

Brazil

Message

At ZeroRisk, I built an AI-powered platform for third-party vendor risk and compliance, including an autonomous vetting pipeline that gathers evidence and generates assessments against standards such as SOC2, ISO 27001, GDPR, and HIPAA.

I architected its Ruby on Rails API and React/TypeScript application, then deployed and operated the platform on AWS. I also added reliability measures for background processing and wrote RSpec tests covering vetting logic and access control.

At Tolq, I led greenfield development of a translation-management platform for B2B clients using Next.js, React, TypeScript, Node.js, and GraphQL. I also maintained legacy applications and improved the platform’s frontend and email templates.

Earlier, I built products across banking, healthcare, e-commerce, and solar project sales. At LIV Saúde, I reduced latency in a core Node.js service from 60 seconds to 200 milliseconds, and at Neurogram I developed Cardium, a React Native app for AI-assisted ECG analysis.
