Acerca de Joel
I’m a versatile Full-Stack Software Developer with 6+ years of experience across backend, frontend, and DevOps. I help companies build, improve, and maintain web applications that are reliable, scalable, and user-friendly.
My expertise spans Java, Spring Boot, JavaScript/TypeScript, React, Vue.js, Node.js, and databases (SQL & NoSQL), combined with hands-on DevOps knowledge (CI/CD, automation, Linux).
I’ve worked in finance, SaaS, and digital platforms, contributing to banking systems, trading tools, and startup products. I enjoy joining existing teams, strengthening codebases, and delivering clean, maintainable features without overcomplicating things.
I typically handle:
Backend development & API integration
Frontend implementation with modern frameworks
Database design and optimization
SaaS product development and deployment
What sets me apart: I adapt quickly, I’m collaborative, and I focus on making software practical and sustainable. If you need someone reliable and with a good sense of humor to reinforce your team and deliver solid code, I’d be glad to help.
