Hi, I'mMatías Hernán Guevara
I craft exceptional digital experiences with code, creativity, and a passion for innovation.
About Me
I'm a passionate software engineer with experience building web applications and digital products. I specialize in software development with React and Next.js, Golang, NodeJS with Express, databases like PostgreSQL and MongoDB.
More than 7 years of experience as a Software Developer. I headed product migration with traffic of more than 5 million daily users, and the creation from scratch of different projects, applying new trends such as Micro-Frontends, achieving scalability in the products. Fan of DevOps culture and exploring new technologies.
When I'm not programming, you can find me exploring new technologies and finding my place with my own startup.
