About Me

Hello, I am Nelson, currently serving as CTO and Full Stack Developer with expertise in infrastructure, application deployment, implementation, management, and monitoring.

With a strong focus on digital sustainability, I believe in choosing technologies that are efficient, scalable, and environmentally conscious. I have two kittens 🐱 and I love to be on the top of the edge in terms of tech.

My expertise spans Technical Leadership, DevOps, Platform Engineering, and Blockchain Advisory.

Currently focused on blockchain platform development and advisory.

I'm a very pragmatic guy. Currently, I work with technologies that get the job done efficiently:

Node.js
Docker
Kubernetes
GitHub
Blockchain
Cloud

The Journey

My mission is simple yet profound: transform ideas into living, breathing digital products. I thrive in that magical space where a brilliant concept meets the real world.

From picking the perfect product idea to engaging passionate teams, I orchestrate the entire journey of making products publicly availableand accessible to the world.

As a DevOps and Platform Engineer, I'm the digital architect who ensures products don't just launch—they stay online, scale gracefully, and evolve continuously. I build the invisible infrastructure that makes everything just work.

My toolkit includes automated deployments that flow seamlessly from Git, monitoring systems that never sleep, and processes so smooth they make development teamsfall in love with shipping code.

And yes, I absolutely ❤️ AI agents like Claude Code and GitHub Copilot. They're not just tools—they're force multipliers that unlock our potential to domore,better, and inless time.
