About me
Hi! I'm William Gonçalves 👋
Senior Front-End Engineer with 10+ years of web development experience, backed by a 20-year professional career in engineering environments. I specialize in React architecture (Remix, React Router, Next.js), TypeScript, and Design Systems.
Currently leading front-end architecture at ConstruCode, I have conducted complete platform migrations (.NET Legacy → Next.js → Remix) and established the company's Design System. I focus on technical decisions that directly impact performance, maintainability, and developer experience.
In parallel, I'm focusing on AI Engineering — developing expertise in Generative AI, RAG, and Agentic AI to integrate intelligent solutions into my work as a software engineer.
My background is distinct: I built a strong foundation in Computer Science fundamentals during my early academic studies (2006–2010) before spending 13 years managing critical infrastructure for enterprise clients. This experience instilled a zero-tolerance mindset for failure.
A highlight in my career as a creative was creating the first public transportation map of Rio on Moovit, work that was featured in "O Dia" newspaper.
