About Me
My name is Rafael Esposito and I’ve been developing software for over 10 years. I’m a results-oriented
developer with a strong focus on code quality and user experience.
I have experience in both back-end and front-end development, as well as in building cross-platform
applications. I work with languages such as JavaScript, Java, PHP, and TypeScript, and have deep knowledge of
relational databases (PostgreSQL, MySQL) and non-relational databases (MongoDB).
Since 2018, I’ve enthusiastically embraced a freelance career, collaborating with startups, companies, and
professionals to turn ideas into solid, high-performing digital products with attention to detail.
I believe in the value of robust software that is easy to maintain and built to last. I speak Italian and fluent
technical English.
