ABOUT ME
Software Engineer ● Node.js & Deno contributor
Software Engineer ● Node.js & Deno contributor
I'm a software engineer based in Madrid who loves working with Deno, Node.Js & Ethereum.
I have been a self-taught programmer since 2009 when I was 19 years old. Since that moment I've never stopped learning. These days I spend most of my time building Node.js applications, Smart Contracts and contributing to Deno.
If you want to improve your skills in Javascript, Node.js, or Deno don't hesitate to get in touch.

I'm passionate about Node.js, I use it everyday. I've built hundreds of APIs, websocket servers, scrapers, smart contract integrations, using always the latest javascript features.
I can detect performance bottlenecks with just glancing at your code. I write simple, clean and fast code, so if you need help with code refactor/review, just let me know!
I'm a Node.js contributor, and I have a special interest in streams.

JavaScript is the language I love and use the most. Almost every project I work on uses it, either on the back-end or the front-end.
I can explain you how JS really works, the event loop, the latest features: async/await, iterators, arrow functions, classes...
I know & understand all the errors that are thrown, so if you show me a stack trace, I can solve your problem.

I've been installing/maintaining Linux servers ever since I started programming. I can install any stack in an Ubuntu server in 5 minutes.
I use Ubuntu as my OS, so I know my way around the terminal, grep/awk/find/tail are a part of me.

Marcos quickly understood the challenge I had and was able to find and implement a solution which works. It was my first time using codementor and I will definitely be back.

Preposterously Intelligent and straighforward guy, literally solved my problem when no one else could. I wish I'd seen him earlier though..

Marcos was so quick and professional. He took time to understand the problem and once he did he went straight to helping me fix my project and explain to me best practices. If you are even thinking about getting a mentor do so now.

I have had sessions with over a dozen mentors. Marcos is the absolute best. He has always solved my coding problems. He then explains the solution so clearly.
