Rational Performance Tester developer in Spain (UTC+1)

I am a dedicated software developer with over four years of hands-on experience, specializing in Java and the Spring Boot framework. My passion lies in building scalable, efficient web applications, and I've honed my expertise in back-end development, particularly using modern Java technologies. Throughout my career, I've demonstrated the ability to solve complex problems and deliver high-performance solutions while collaborating with cross-functional teams in Agile environments. My goal is to continue leveraging my technical knowledge in Java and Spring Boot to build impactful, reliable software systems that meet real-world needs. I have a strong background in full-stack development, with a particular emphasis on Java back-end technologies. Over the years, I have gained substantial experience with Spring Boot, Maven, PostgreSQL, and Azure DevOps. I am also familiar with front-end technologies like Angular, though my core focus remains on back-end development. I am comfortable working with CI/CD pipelines, utilizing tools like JIRA, and ensuring code quality through test-driven development and performance optimization techniques.

Vetted Rational Performance Tester developer in Spain (UTC+2)

● +20 years non-stop programming ● V8 (Node.js/Chromium) enthusiast ● I'm a self-taught programmer since 2001, when I was 14 years old. I professionally work as a developer for 13 years now, when I created my first company. I've been part in tons of projects of multiple kinds, using low-level languages like assembly or the good ol' C, or high-level languages like Java, Visual Basic, C#, JavaScript, Ruby, ActionScript or PHP, although the last 10 years I'm focusing more in JavaScript and its ecosystem, so when I discovered Node.js it was a blast for me. Almost all my projects are focused around Node.js since then. I also LOVE teaching, so if you want to improve your skills don't hesitate to get in touch :-)

Hi there, I'm Ángel, a javascript developer located in Spain. I have a long experience as a Front-end developer in all the most popular frameworks as well as experience in QA testing oriented to e2e testing. I love working with javascript, it is my favorite framework and I really like to adapt to any new framework that appears, integrate it, get the best out of it and be in continuous learning. Right now I'm looking for a remote position as a front-end developer. I enjoy collaborating with the design team, the product team and the testing team to integrate the best solution that makes everyone happy at the same time. For this reason I would like to find a friendly work environment where everyone feels comfortable and can contribute their ideas. My favorite technologies are Angular and Vuejs, although I insist I adore learning new frameworks and adapting to any type of need that the team has.
