About Me

Software Engineer with over 15 years of experience leading and developing results-oriented technology solutions. My work is driven by generating real business value, aligning technical decisions with the organization's strategic goals.

Throughout my career, I have built strong experience as a Full-Stack Engineer, with end-to-end ownership of the development lifecycle — from architectural definition to delivery and production support. I design and build scalable, secure and high-performance systems using technologies such as PHP, Python and Node.js, always focused on operational efficiency and sustainable growth.

I currently focus on software architecture and technical standards definition, contributing to more robust, predictable and scalable environments. I continually seek to balance technical excellence, product vision and measurable business impact.
