Liore
Freelance Senior Software Engineer, March to September 2026. I built an internal management system for a medical platform from scratch with React, Next.js, TypeScript, Node.js, and MongoDB. I designed APIs for patients, doctor scheduling, appointments, payments, and administration, with server-side rules for availability, appointment validation, and permissions. I modeled the data with Mongoose, shipped REST APIs with JWT and role-based access control, added real-time notifications with Pusher, and owned the architecture through deployment on Vercel.
Kyle Real Estate
Freelance Senior Software Engineer, May to June 2026. I built a real estate website from scratch with Next.js, TypeScript, and Node.js.

Abercrombie & Fitch
Senior Software Engineer, remote for the United States, November 2022 to March 2026. I developed internal management systems and e-commerce platforms with React, TypeScript, Node.js, and GraphQL, and kept API and UI documentation current. I was the lead frontend developer in a pod, guiding developers and leading four SPAs for internal operations. I contributed to creating and standardizing 30+ microservices, migrated legacy JavaScript applications to TypeScript and Vite to improve performance and maintainability, maintained internal libraries, and joined the core e-commerce transition from Java to Next.js. Day to day I used GitHub Copilot, Cursor, Claude, and ChatGPT.
ConectaDoc
Junior Software Engineer, remote in Brazil, May to November 2022. I migrated the company website to React and TypeScript for a healthcare platform used by international clients, built white-label React Native apps for partner brands, and integrated the interfaces with backend APIs. I joined technical decisions with stakeholders and improved quality through debugging, refactoring, and feature ownership.
Kenzie Academy Brazil
Technical Mentor, remote in Brazil, March 2021 to May 2022. I led mentorship for full-stack students in JavaScript, React, Node.js, and engineering practices. I created tasks and projects from scratch in React, TypeScript, JavaScript, Node.js, and Python, and reviewed student work for code quality, logic, and readability.
Currently seeking Senior Software Engineer opportunities where I can apply my expertise in modern web technologies and system architecture to build impactful products.
