Matheus Pereira

Software Engineer | Frontend | Web, Data & IoT

About

Software Engineer focused on frontend, with experience across web interfaces, data workflows, automation, and IoT. I build practical tools and experiments with an emphasis on readable interfaces, performance, accessibility, and codebases that stay easy to evolve.

Most of my public repositories are personal projects built end to end, from interface design and application architecture to deployment and maintenance. They are open source studies and utilities rather than commercial products, but I keep the public demos and descriptions aligned with what each project currently does.

Areas of Expertise:

  • Frontend applications with React, TypeScript, and JavaScript
  • Backend APIs, automation, and integration workflows
  • Data analysis and visualization
  • Embedded systems and IoT prototyping
