software developer · london, on

Hello! I'm Carlos, a full-stack software developer based in London, Ontario. I'm passionate about building reliable, well-crafted software that genuinely improves the lives of the people who use it — whether that's a polished web app, a handy automation script, or a mobile experience enjoyed by millions.

Shortly after graduating from McMaster University I joined DemandHub as a full-stack engineer, where I work on messaging tools that help small and medium-sized businesses attract, engage, and retain customers.

During my studies I spent 16 months at Bell Canada as a co-op software developer, building in-house analytics and automation tools for the Core Network Team. I also stepped into the Scrum Master role for 6 months, facilitating bi-weekly workshops for a 5-person team.

As an entrepreneur I founded CS Software — a web design and app development venture. My app Touch Roulette – Decision Maker has surpassed 1 million downloads on the Google Play Store.
