Lucas Moura

I’m a Software Engineer with 5+ years building scalable, high-performance web applications. I specialize in React and Next.js—working with both SSR and CSR patterns—and I pair that with strong TypeScript focus.

I’m deeply committed to modern frontend architecture and maintainability, applying Clean Architecture, Clean Code, SOLID, and Agile/Scrum methods. At Singular, I owned Next.js/React/TypeScript frontend development, integrating external APIs for CRUD and file export while building features for the globally used B2B platform Zeitten.

I focus on performance and responsiveness: I implemented a dynamic favorites system with isolated state management and cache synchronization, and I helped drive an optimization effort that reduced unnecessary re-renders dramatically. I also structured multi-step form architectures with careful loading, error handling, pagination, and file upload/download support, including customized Markdown editing.

Beyond the frontend, I contribute to backend and data modeling: at Singular I worked with C#, .NET Framework, Entity Framework, and PostgreSQL (DDL/DML/functions). Previously at Meta, I built stable production systems using Angular, Java, and OracleDB, including API and database modeling work, caching to avoid unnecessary requests, and refactoring legacy scheduling logic; I also apply AI tooling like Claude Code to improve development workflow and task planning.
