About

Professional summary

I am a senior full-stack and AI engineer with more than nine years of experience building web and mobile products for US and Brazilian companies. I specialize in React, React Native, Next.js, TypeScript, and AI-enabled engineering systems.

I currently work on TED.com, a platform serving more than 20 million monthly visitors, and the TED mobile app, which has more than 30 million Android downloads. I build performant, localization-aware, accessible user experiences across web and mobile platforms.

I have delivered React Native applications to both the App Store and Google Play, led an eight-person engineering team, and owned front-end architecture for multiple client products. My experience spans product delivery from stakeholder scoping through launch, production monitoring, and ongoing quality improvements.

I prioritize software quality, reliability, accessibility, and measurable user impact. I use test-driven practices with Playwright, Jest, React Testing Library, CI pipelines, New Relic, Bugsnag, and production monitoring to prevent regressions and improve release stability.

I also build AI engineering systems including LangGraph agents, MCP servers with access controls, RAG workflows, evaluation gates in CI, prompt-injection guardrails, and human-in-the-loop approval flows. I publish open-source tooling for Claude Code and AI agent reliability.

I have worked remotely with distributed US teams for more than five years and hold EU work authorization. I am based in Portugal and can collaborate effectively across EU and US time zones.

Career history

Senior Full-Stack Engineer TED Conferences

I work as a front-end engineer for TED.com and the TED mobile app, collaborating with product, design, and back-end teams across multiple time zones. I architect page rendering and content delivery for TED.com using Next.js, React, GraphQL, Tailwind CSS, and Prismic CMS for a platform serving more than 20 million monthly visitors.

I support performance and release stability for the React Native TED app, which has more than 30 million Android downloads, using New Relic to prioritize production fixes by user impact. I build localization-aware experiences for a library of more than 3,000 talks with subtitles in over 100 languages.

I own Playwright end-to-end coverage and Jest unit testing in CI, implement WCAG 2.1 AA accessibility practices, and use spec-driven and test-driven workflows with Claude Code agents under human review, scoped permissions, and quality gates.

Senior Software Engineer Popstand

I delivered web and mobile products for multiple concurrent US clients in a product studio, working directly with stakeholders from project scoping through launch. I shipped the RadStar Alpha Series, a tablet-first React Native application for professional radon testers, to the App Store and Google Play from a shared iOS and Android codebase.

I also shipped the Melanin Medical Specialties React Native application, including mentor matching, a searchable community provider directory, and peer-support features. I owned front-end architecture for production web platforms using React, TypeScript, and Next.js.

I launched a Web3 digital art marketplace with wallet connections, smart-contract interactions, IPFS asset storage, and Algolia search. I improved code quality and post-launch stability through Jest coverage, New Relic monitoring, and Bugsnag error tracking.

Senior Full-Stack Engineer Supero TI

I worked in a seven-person team building mission-critical maintenance systems for Engie's power generation assets across Brazil. I built React operational interfaces and Node.js/TypeScript APIs used by plant operators to coordinate maintenance shutdowns across hydroelectric, thermoelectric, and wind power plants.

I strengthened API error handling and optimized high-volume asset queries in Oracle Database for a system where downtime had direct revenue and regulatory consequences. I also standardized local development environments by containerizing the application stack with Docker.

Software Development Lead GETMORE Brazil

I served as technical lead for a loyalty and engagement platform, owning back-end, web, and mobile workstreams. I led a team of eight developers across back-end, front-end, and React Native development by setting coding standards, running code reviews, and defining delivery cadence.

I architected a React web client, React Native mobile application, and Node.js services on a shared PostgreSQL data model. I shortened release cycles by introducing Docker-based environments and standardized branching and review processes.

Full-Stack Developer SESI

I built a wellness coaching application that delivered personalized health programs to industrial workers. I worked with a Java back end, Angular front end, and MySQL database.

Software Development Intern SumOne

I contributed to client web applications using JavaScript while completing my Information Systems degree.
