Who am I?
👋 Hi, I’m Alex Castillo,I am a passionate Full-Stack Software Engineer with a knack for quickly learning new tools and paradigms. I spent over a year at Microverse, where I collaborated with developers worldwide, honing my skills in JavaScript, HTML, CSS, Ruby on Rails, and various frameworks. This experience taught me the importance of adaptability and continuous learning, which I’ve carried into my professional journey.
Following my time at Microverse, I joined IcaliaLabs, where I have been working for the past 2.5 years. Here, I’ve been developing high-quality web applications and leading collaborative teams using tools like Docker, Compose, Bash scripts, and Google Cloud to meet project deadlines and achieve our goals. My diverse experiences have equipped me with the ability to thrive in dynamic environments and foster a culture of constant growth and innovation.
