About

I’m Joel Abril Madrigal, a software developer with over 4 years of experience designing and implementing scalable, high-performance web applications. Since 2023 I have focused on frontend development with React, Next.js, and Vite.js, complemented by strong backend experience with Node.js, Express, and Java. I have worked on blockchain projects, developing smart contracts in Solidity and integrating them into full-stack applications.

I thrive in agile environments, delivering reliable and modern digital solutions. I’m skilled with PostgreSQL, Azure for cloud deployments and AI agent development, and I enjoy collaborating with cross-functional teams to turn complex requirements into robust platforms.
