Portfolio

Software, infrastructure, and networks connected by an engineering mindset.

I am Marcos, a fullstack developer with an electrical engineering background, years of hands-on work with networks and infrastructure, and the last 4 years focused more directly on web development.

I build practical digital products with a systems mindset, connecting product delivery, software architecture, and real-world operations.

About

A profile that bridges software delivery and operations.

Background

My electrical engineering degree shaped a structured way of thinking about systems, diagnostics, and reliability.

Technical experience

Before focusing more directly on software, I spent years working with networks and infrastructure. That experience now translates into stronger clarity around deploys, integrations, and operating real systems.

Current focus

Over the last 4 years, I have been working more directly as a fullstack developer, aiming to deliver useful products with clean code, technical context, and practical judgment.

Focus

Where I usually create the most value.

Fullstack web

React, Next.js, JavaScript, frontend-backend integration, straightforward interfaces, and product maintenance.

Infrastructure and networking

Linux, containers, troubleshooting, deploys, networking, and a stronger reliability-and-operations perspective.

Tooling and automation

Docker, practical scripts, integrations, and technical shortcuts that reduce friction in everyday work.

Projects

A curated selection of technical work and interests.

Infra + Docker

mediawiki-pg

A MediaWiki container with PostgreSQL and LDAP support, shaped around realistic deployment, authentication, and administration scenarios.
