Isaac Hermel Reginato

Software Engineer | React Architecture & Performance Optimization | System Design | Node.js & TypeScript

Engineer focused on scalable architectures and performance within the JavaScript/TypeScript ecosystem — from high-throughput data ingestion (59k+ records/min peak) to front-end rendering bottleneck resolution.

Focus: SSR/SSG optimization · Component-Driven Architecture · Core Web Vitals · Shift-Left Testing (TDD/BDD) · Layered architecture with dependency injection · CI/CD & zero-regression pipelines

Professional Impact

  • Zenvia — Co-owned ETL ingestion pipelines at 59k+ records/min peak, with front-end ownership across these projects. Structural front-end refactor (React.js, Component-Driven Architecture) moving Core Web Vitals into the "good" field range (LCP 2.91s→2.35s, INP 275ms→199ms).
  • Catency — High-conversion B2B interfaces in Next.js with hybrid rendering (SSG/SSR): 5 platforms at consistent LCP < 2.5s.
  • Umbler — End-to-end internal tools (.NET, Blazor, MVC), automating base management for 100,000+ clients.
