About me
Halisson Alves
Senior Frontend Engineer with 8+ years of experience.
Background
Most of my career has been frontend-first: React, Next.js, React Native, TypeScript. But I've always been curious about what happens after the request leaves the browser, and that curiosity turned into real backend experience with Node.js, NestJS, and some Python along the way. After 8 years, I can take a feature from idea to production without handing it off.
Things I've built
I developed a socio-emotional support application designed for students from over 400 schools across Brazil.
Built a system for a pharmaceutical equivalence and bioequivalence company, optimizing critical workflows.
Developed a mobile app for traffic officers in Angola, improving infraction control and field operations.
Created a shift management platform for Raízen, increasing accuracy in team operations.
Implemented a donation and payment system for an NGO, enabling better fundraising processes.
Currently
I work as a Senior Frontend Engineer at Arco Educação, building scalable and high-performance applications used in the education ecosystem in Brazil. More recently, I've been heavily involved in AI-assisted development workflows, using tools like Cursor and Claude Code. I work daily with structured LLM workflows, including internal MCPs, to improve development speed, code quality, and overall productivity.
