About
Senior software engineer with 8 years of industry experience, including 2 years of remote work for US companies. Frontend Leader known for promoting a culture of clean code and best practices in cross-functional teams.
Currently pursuing a Software Engineering MBA program at USP, the top-ranked university in Latin America. Proficient in React and Typescript, committed to delivering high-quality solutions that drive business success.
I am diligent when it comes to code quality, questioning myself: Am I being clear, transparent enough? Could it be simpler? If someone new jumps to the project, would get what's going on?
Don't hesitate to message me if you have some questions, for changing some words or any potential project partnership. I am looking forward for your contact.
