Senior Backend Developer · Mentor · Speaker

🚀 Senior Software Engineer | Barcelona, Spain 🌍 🛠️After several years of experience developing APIs in high-traffic environments and learning about testing, best practices, architecture, and more with PHP, I changed to Kotlin because the programming language is just a tool that allows us to give value to our users. 🎤 Sharing knowledge is one of my passions. I’ve participated in different online and in-person events talking about testing, also taught about it at university for three years, as well as architecture and best practices. Those are topics that I also share with my teammates. 👩🏻‍💻 After starting with Kotlin, I also create a couple of courses on how to start with Kotlin and develop an API following ports&adapters architecture with Kotlin. 🌟In recent years, I joined Step4ward as a mentor and now as a co-organizer, a community dedicated to helping grow and succeed women in technical careers.
