About Me

🧑‍💻 About me
I'm a software developer passionate about technology, specializing in programming and systems administration. Since I started in IT, I've enjoyed solving real-world problems with code, learning firsthand how a system works internally, and constantly advancing in areas like systems administration, scripting, and cybersecurity.

My curiosity about cybersecurity has led me to delve deeper into concepts of protection, process analysis, and technical automation, always with a practical and results-oriented approach. I am currently developing my own projects, which allow me to stay up-to-date with the rapid pace of technological advancements and provide higher quality instruction in my classes.

I have also competed in technical events: I won a silver medal at Andalucía Skills 2025 in the specialty of Network Systems Administration, which demonstrates my technical ability and commitment to practical excellence.

📚 My way of teaching
I like to teach in a clear, practical, and approachable way: nothing excites me more than seeing someone go from thinking "I don't even know where to start" to "I can do this myself." My classes are designed so that each concept has real-world applications from the very first minute, with exercises you can use in your own projects.

This is what I offer in my programming and technology classes:
Step-by-step explanations, without unnecessary jargon
Real code, not just theory
Exercises applied to practical situations
Close support and answers to your questions right away.
A pressure-free environment where you can learn at your own pace.

🚀 What skills should I bring to your classes?
✔ Connection between theory and real projects.
✔ Continuous and real learning.
✔ Ability to think like a computer scientist.
✔ Advanced knowledge and personal experience.

💡 My promise
I'm not just going to teach you "what something does."
I'm going to teach you how a developer thinks, how to structure code professionally, and how to solve real-world problems using programming.

If you really want to learn, from someone who has practiced and applied what they teach, I'm here to help you.

If you want to quickly and effectively become a Web Developer, then you’re in the right place! I offer a practical explanation of all the skills and tools necessary to become a Web Developer with an emphasis on Frontend Web Development.

What is Frontend Web Development?
It Is the design and implementation of graphical user interfaces, necessary for the creation of websites and applications. In practice: designing a page layout, displaying of information and graphical media, data management and allowing user interaction via buttons, forms, links, etc.

I’ve been a Frontend Web Developer for the past 8 years. I deal with the aforementioned topics on a daily basis and in my free time I help others on joining this career path. I focus on the abilities that are currently of interest to potential employers.

My course is not set in stone and its primary goal is to:
- quickly establish which path you want to take (Frontend has many subspecialties)
- making that vision a reality in the shortest possible timeframe

Below is my recommendation of the topics, that I will help you master, split into 3 sections with an increasing level of difficulty.

Module 1 - introduction, understanding the basics and preparation for future study
- HTML - learn the technical structure of simple websites
- CSS - learn how to apply styles and layouts to your projects and display them properly on different devices
- JavaScript - you will gain basic knowledge, that will allow your project to become interactive

Module 2 - tools and tech needed to work on industry-level projects
- frameworks used to create complex pages. There are many options, I suggest React and/or Wordpress
- Git versioning system - simplifies the workflow, necessary when working in a team
- testing: an introduction to testing tools which will ensure that your apps are stable and run smoothly

Module 3 - more specific topics, that will surely impress a potential employer. Moreso than in other modules, the content of this one is entirely dependent on your preferences, here is a short overview of potential topics:
- search engine optimisation (SEO)
- hosting a website on a server
- advanced data management tools/techniques (e.g. Redux)
- implementation of tracking systems (Google Analytics, Google Tag Manager)
- website security best practices
- correct implementation of cookies
- user account management, authorisation, registration, logging in - ChatGPT and other AI tools that can help you become a better programmer

Thanks for reaching the end of my offer. Get in touch!

Electric current is a flow of electric charges, such as electrons, passing through a conductor, such as copper wires, because they are considered conductors, so their electrical conductivity is high and their resistivity is low.
From this, we can deduce a definition of electric current intensity as the amount of electric charge that passes through a specific cross-section of a conductor in one second.
