Marcos LebronSenior Full-Stack Engineer building scalable SaaS and AI-enabled products

I design and ship production-grade software systems across frontend, backend, and cloud infrastructure — with a focus on architecture, maintainability, intelligent workflows, and real business impact.

From product experiences and internal platforms to APIs, automation, and AI-powered features, I build systems that are meant to scale in production.

About

I’m a software engineer with a strong focus on modern frontend systems, full-stack product development, and platform architecture. Much of my recent work has been in private repositories, building production applications involving React, TypeScript, Node.js, AWS, shared UI systems, and scalable delivery practices.

  • 7+ years building web applications
  • React / TypeScript / Node.js
  • AWS / scalable platform work
  • Architecture + performance mindset

Writing

Notes on frontend architecture, AI-assisted development, and building production-ready systems.

How AI changed my development workflow

The practical way I use AI for prototyping, debugging, testing, and architectural iteration.
