   Full-stack product · 2026

   Dumphere

   A public document editor with real-time collaboration, offline support and URL sharing, with no account required.

   My contribution

   I designed the end-to-end architecture, with rich editing in Tiptap, Yjs synchronization over WebSockets on a dedicated Node server, snapshots persisted in PostgreSQL and a per-document local cache in IndexedDB. On the server, HTML is sanitized before it is stored, document creation and connections are rate-limited per IP, and a scheduler removes documents untouched for 30 days. The interface is bilingual and covered by Pest tests.

   Public platform · 2026

   Categoriza Brasil

   An ecosystem for food-service health ratings, connecting public information, establishments and institutional management.

   My contribution

   I built the platform on a domain-modular architecture that brings together the public site, admin panel, identity and authentication, accounts, application clients and the institutional area. Its centrepiece is establishment registration wired to the Google Places API, where an autocomplete search pulls in the name, the address split into fields, coordinates, phone, website and a cover photo, then translates Google's categories into the platform's own food-service categories. Dragging the map marker triggers reverse geocoding. I also built the publications and media CMS backed by S3 storage, the public map with clustering in Leaflet and the test suite that covers the application.

   Component library · 2026

   FUSE UI

   A Vue 3 component library on the registry/CLI model, where the command copies the source into your project. You own the component and can edit it.

   My contribution

   I defined the monorepo architecture, the two-layer design token system (primitive and semantic, in CSS) and wrote the components on top of Reka UI's accessible primitives, with variants in CVA. I publish the CLI to npm and maintain the development Storybook, the bilingual Nuxt documentation, the Vitest suite and Changesets-based releases.

   Applied AI · Master's research

   AETHER

   An AI pipeline that estimates hydrogen adsorption energy and supports catalyst screening for green hydrogen production.

   My contribution

   I built a reproducible pipeline for curation, training, comparison and explainability over 5,860 structures from Catalysis Hub, on a fixed canonical split. I compared four approaches on the same data (handcrafted descriptors, a GNN trained from scratch, a fine-tuned pre-trained equivariant GNN and regression over frozen embeddings), reporting mean and standard deviation across 5 seeds. Results are served through a FastAPI API with a Vue interface.

   Overclock Labz

   A digital experience for a software studio, translating speed, commercial clarity and technical personality into a distinctive interface.

   My contribution

   I created the visual direction and built every interface piece from scratch, with no component library, including the process diagram, the comparison chart, an animated terminal and a canvas mini-game hidden in the site. I wrote the contact API in Nitro with validation, per-IP rate limiting, a honeypot and Turnstile verification, plus the cases and blog in versioned Markdown.

   Institutional website · 2026

   LABED

   The website for UFN's Electronics and Development Lab, designed to make its projects, members and fields of work easier to discover.

   My contribution

   I redesigned the lab's digital presence and built a typed content foundation in TypeScript, with members, projects and sponsors edited as files and no CMS. Every project gets its own pre-rendered page, with a photo gallery, complete SEO and GSAP plus Lenis scroll animation that respects the reduced-motion preference.
