About Me

Driving Success through Technology

I am a hybrid profile that connects Full Stack Development with Service Excellence. My mission is to transform technical challenges into real growth opportunities. With 7 years operating in English for global markets, I master the art of translating business visions into high-impact solutions. My differential value is the balance: I bring the solidity of a developer (React, Node.js) and the strategic agility of an N2 Support specialist. I don't just write code; I optimize processes, drive ROI, and ensure every project exceeds end-customer expectations.
