I build frontends at scale — and the AI workflows that ship them.

Building and evolving mission-critical miniapps used daily by thousands of customers across the Magalu ecosystem.

• Led the adoption of Specification-Driven Development powered by Claude Code, establishing AI-assisted development as the team's standard engineering workflow.
• Applied AI across design, implementation, migration, debugging, testing, and refactoring — accelerating delivery while holding engineering quality steady.
• Migrated a production miniapp from React Native to React + Vite using an AI-assisted migration strategy.
• Led discovery and implementation of biometric fraud-check SDKs inside WebView miniapps, delivering integrations with two national identity providers used daily by thousands of customers.
• Improved reliability and performance through monitoring and analytics — reducing errors and improving First Contentful Paint.
• Strengthened security by mitigating dependency vulnerabilities and keeping applications aligned with secure development practices.
• Contributed to frontend infrastructure planning and provisioning — CDNs, storage buckets, and deployment resources for new applications.

Investment Funds business unit, working across three squads and helping maintain a micro-frontend architecture spanning 20+ repositories.

• Maintained and scaled a micro-frontend architecture across more than 20 repositories, frequently context-switching between squads within a single sprint.
• Established testing standards end to end — Jest and React Testing Library for unit and integration, Cucumber with Playwright for E2E.
• Optimized performance and refactored codebases to improve scalability across micro-frontends.
• Set up new micro-frontends from scratch, configuring Jest, ESLint, and CI/CD pipelines.
• Unblocked other engineers debugging local environment and pipeline failures, reducing time lost to tooling.
• Conducted code reviews, proposed architectural improvements, and enforced company-wide standards.
• Debugged and resolved production issues, and remediated npm package vulnerabilities for security compliance.

Developed and evolved a telecom e-commerce platform for a US-based carrier, spanning hybrid, SPA, and backend-for-frontend architectures.

• Built and maintained a hybrid e-commerce application on JavaScript, Vue.js, Vuex, Drupal, SCSS, Docker, and Gulp.
• Built a self-care SPA on TypeScript, React, Redux, and headless Drupal, served through Nginx and Webpack.
• Built a backend-for-frontend layer with Node.js, Express, GraphQL, and Apollo Server to optimize communication with telecom back-end services.
• Refactored legacy codebases toward Clean Code and single-responsibility, reducing complexity and improving maintainability.
• Contributed to a proof-of-concept application for prospective clients using TypeScript and TypeGraphQL.
• Created knowledge-transfer material that shortened onboarding for new team members.

Feature development and production support across the same telecom commerce ecosystem.

• Developed features and resolved defects across Vue.js, Vuex, React, Redux, Redux-Saga, and Drupal.
• Worked across the GraphQL and Apollo Server layer with Node.js and Express.
• Supported other developers with troubleshooting and maintained clear cross-team communication.

Technical mentoring for web development students, individually and in groups.

• Mentored students across web fundamentals, React, Redux, Node.js, MongoDB, SQL, and computer science topics.
• Ran synchronous content reviews and provided support for student questions.
• Helped developers troubleshoot, and practised giving and receiving structured feedback.

Outsourced to Ceva Logistics at the Mercado Livre service centre, combining operations work with internal tooling.

• Built Excel and VBA solutions for recurring operational problems.
• Handled route planning and package management under time pressure.

Mechanical engineering internship where the software work began — reporting, queries, and dashboards alongside maintenance duties.

• Wrote SQL queries to control preventive and corrective maintenance work orders.
• Built dashboards for maintenance KPI tracking.
• Produced mechanical drawings and nationalized gaskets for imported machinery.
• Contributed to inspection scripts and lockout/tagout procedures.
