Juan Manuel Segura Duarte

Software Engineer | Full-Stack, Systems & Automation

 


I'm a versatile and resilient software engineer who builds robust systems across the full stack. My approach is grounded in a deep, practical understanding of Linux systems administration, from debugging boot processes and writing custom systemd services to managing package repositories and network configurations. This first-principles knowledge of the underlying OS allows me to build and troubleshoot with a clarity that goes beyond just the application layer.

I have a proven foundation in both low-level systems programming (C++, Java) and modern web applications (TypeScript, Node.js, React). I am driven by a passion for automation and the challenge of building clean, scalable, and impactful products.

Below you will find a selection of my pinned repositories, which showcase my capabilities across different domains.
