Background
About
I'm a FullStack Developer with a strong technical background and a deep passion for technological innovation. I specialize in architecting and developing comprehensive solutions across both Frontend and Backend ecosystems.
My approach is rooted in understanding the logic and flow between layers, applying best practices, design patterns, and agile methodologies to create scalable, efficient products focused on user experience.
With experience in React, Angular, Next.js, Express, Django, .NET, and both SQL and NoSQL databases, I thrive on building intuitive interfaces and robust backend systems.
