I've been breathing technology since 2000, when I started developing my first web pages as a teenager hobby. In 2007 I graduated in Computer Science, the same year I started working as a developer. During all these almost 15 years, I have worked as Systems Analyst, Full Stack Developer, Frameworks Architect, Product Designer and Tech Lead. In my journey, I've dealt with many development technologies. In particular, I highlight Java, where I acquired vast experience, mainly, developing web & mobile applications with microservices, concurrency control and integrations. In 2015, I developed a MVP to solve a personal issue: a smart RSVP to my child’s 1st birthday would bring me money saving. The MVP became real business in 2017. As the CTO, I improved leadership and planning skills. I needed some resourcefulness to implement and promote it (B2C/B2B), having to deal with all kinds of issues (team collab, planning, modelling, coding, UX, hosting, security, training, market fit, customer care, etc).
