Senior Front-End Developer at Solsten

Lead dashboard development for two products (Traits and Navigator) with a high number of functionalities, numerous state combinations, and complex business rules. Implemented content sections with profile-based permissions, preview mode with UI obfuscation and data shuffling, and white labeling integrated with external authentication. Extensively used visualizations (D3, etc.) to elucidate entities and relationships. Produced detailed design and UX artifacts. Collaborated with the Front-End team to reduce backlog, while addressing technical debt to prepare for a 2.0 specification. Currently exploring a greenfield project involving LLM, including architecture layers (i18n, mocked content, external authentication, persistence via query params) and experiments/prototypes. Executed migrations and refactoring to smaller, composable parts, including moving from CSS modules to styled components and from Redux Saga to Redux Toolkit with useEffect, and evaluating schema-based solutions (GraphQL

Senior Front-End Developer at Expertlead

Led decisions related to front-end architecture and maintenance of core products. Ported rudimentary, class-based components to modern hooks/macros to reduce boilerplate and improve extensibility and reuse. Built the company’s most complex UI product from scratch: a candidate interview tool with categorized questions, interview workflow, and detailed reports. Also led projects as a form manager using macros and Formik, contributing to scalable, reusable UI components and patterns.

Senior Front-End Developer at Sellics

Designed the first front-end architecture to be adopted across multiple products, migrating features from a Java/JSF monolith to React. Created an abstraction over Redux (and redux-persist) to simplify state management and persistence in local storage, enabling seamless integration with varied services (REST, GraphQL, etc.) without tight coupling to the UI. Contributed reusable dashboard components (currency, modals, tables, tree structures) and a status/async handling layer with retry, undo, and optimistic updates, pre-dating similar patterns in later GraphQL tooling. Initiated open-source components for core dashboard UI patterns and migrated code to hooks.

Lead Front-End Developer at Artirigo / Proxipedia

Remote-from-Brazil engagement evolving into a Lead Front-End role in Germany. Rebuilt the product from scratch, shifting from a content-entity-centric approach to a feature-centric model (datasets, forms). Implemented architecture decisions to shrink the codebase, share behaviors, and reduce duplication via macros and HoCs. Focused on performance, maintainability, and scalable delivery, including cross-content navigation and recursive structures. The project served as a laboratory for architectural modernization, although it was interrupted due to organizational issues.
