Eduardo Navajas

👋 Hi, I'm Edu

My name is Edu, and if there's one thing I've learned throughout my career, it's that I love tinkering with anything that involves code. Yes, I've flirted with frontend, backend, and even winked at DevOps. But you know what? What really drives me is technology as a whole.

I'm not the type to stand still. Labels don't suit me. I love learning new things, getting into tech messes, and above all, finding creative solutions to problems I didn't even know existed until I stumbled upon them.

This blog is my excuse to not end up talking to the walls. Here I'll share ideas, experiments, and maybe the occasional rambling about the latest tech that's obsessed me. Because at the end of the day, if I don't share it, what's the point of having learned so much?

So, if you like exploring, innovating, or simply enjoy reading someone who probably has too many browser tabs open, you're in the right place!

Why this blog?

For years I consumed tutorials that explained the "what" but not the "why". This blog was born from the frustration of following steps without understanding.

✅
Real code I've tested Not theoretical examples, but code I use in my own projects
✅
Bugs I've encountered And how I fixed them, so you don't waste time with the same issues
✅
Honest comparisons Based on real usage, not marketing specs
✅
Additional resources Repositories, configurations and scripts you can download

Frequently asked questions

What technologies do you mainly work with?

I work with Java, Spring Boot, Python, and Angular, although I'm always trying new tools. I like to stay current with trends without losing sight of proven technologies. The important thing isn't the stack, but solving problems elegantly.

Are the tutorials free?

Yes, all blog content is free. The goal is to share knowledge in an accessible way. If the content is useful to you, the best way to support me is by sharing it or subscribing to the YouTube channel.

Can I use your code in my projects?

Tutorial code is available under MIT license unless otherwise specified. You can use, modify and distribute it freely. I only ask that if you improve something, consider sharing it with the community.

Do you offer mentoring or consulting?

Occasionally yes, mainly for companies or developers who need specific help. Write to me and let's talk.
