Acerca de Mario
Mario Fernández Álvarez
Full-Stack Developer · Freelance
---
5+ years building custom software for SMBs and startups across **healthcare, renewable energy, e-commerce, hospitality, and legaltech**. I've worked on dozens of freelance projects — each one in a different world, and that's exactly how I like it. I don't do cookie-cutter solutions.
I've founded my own companies, shipped products with global reach, and collaborated with international clients. I move fast, think creatively, and care about the business problem as much as the code.
I build full-stack web applications — backend architecture, APIs, user-facing interfaces — designed to digitize manual processes, automate operations, and scale with your business. If it can be turned into software, I'll make it work.
Business first, code second. I deliver in phases, communicate clearly, and skip the tech jargon. If you want someone who truly gets involved in your project, let's talk.
