Software Engineer | React Architecture & Performance Optimization | System Design | SSR/SSG | Node.js & TypeScript
Engineer focused on building scalable architectures and optimizing performance within the JavaScript/TypeScript ecosystem. Coexistence of high-throughput data ingestion pipelines (~59,000 records/minute) and front-end rendering bottleneck resolution.
| Domain | Core Stack | Engineering Focus |
|---|---|---|
| Frontend Architecture | Next.js, React.js, Vue | SSR/SSG optimization, MVVM/MVC patterns, Core Web Vitals (LCP < 2.5s), CLS mitigation, and Shift-Left Testing. |
| Backend & Distributed Systems | Node.js, NestJS, Python, .NET | Hexagonal Architecture, Asynchronous messaging (Kafka), Relational/NoSQL modeling, and Event Loop Optimization. |
| Quality & DevOps | Docker, Kubernetes, ArgoCD | GitOps, TDD/BDD workflows, CI/CD pipelines, and zero-regression deployment models. |
Role: Architect & Maintainer Reference implementation for mission-critical React applications.
- Architecture: Shift-Left Testing approach using TypeScript, Vitest, and React Testing Library.
- Impact: Enforced TDD/BDD methodologies for validating complex UI domains, establishing a predictable model for engineering teams.
Role: Core Engineer Open-source platform containing 50 React hooks.
- Architecture: Documentation ecosystem integrated with content-collections and distribution architecture via shadcn.
- Impact: Scalable infrastructure for package integration serving ~100 active users.
Role: Contributor Open-source visual components library.
- Architecture: Implemented Lazy Loading and render control via memoization hooks (useMemo, useCallback).
- Impact: Reduced computational cost (~5KB less in bundle) and optimized component lifecycle performance.
- Zenvia: Maintained ETL ingestion pipelines handling 59k+ records/min peak throughput. Executed structural refactoring of front-end using React.js and MVVM, achieving a 20% rendering performance gain and 200ms reduction in TTL.
- Catency: Engineered high-conversion B2B web interfaces using Next.js. Applied hybrid rendering (SSG/SSR) to deliver 5 platforms with consistent LCP < 2.5s and absolute responsiveness.
- Umbler: Developed end-to-end internal tools using .NET, Blazor, and MVC architecture, automating customer base management for 100,000+ clients.
