Joaquin Dolcemascolo

Hey, I'm Joaquín 👋

I’m a Software Engineer currently working at Mercado Libre. I enjoy building web interfaces, learning constantly, and sharing knowledge while solving real problems with my team.

About me

I enjoy building software that feels clear and easy to use — both for users and for the people who maintain it. I’m especially interested in how small technical decisions impact products over time.

I like collaborating closely with others, asking questions early, and sharing ideas or learnings when something works well (or doesn’t). I’m naturally curious, enjoy learning new tools and approaches, and I’m always looking for ways to improve how we build things as a team.

Outside of shipping features, I care about writing clean, understandable code and creating environments where people feel comfortable contributing and growing.
