About
Full Stack Developer with over a year of professional experience across product companies and consulting / software development for clients.
Experienced in frontend and backend development with JavaScript, React, Node.js and Express, building new features, maintaining and evolving existing applications, integrating REST APIs, handling authentication and troubleshooting issues.
In product teams I worked on continuously evolving applications — understanding existing functionality, fixing issues and shipping incremental improvements. In consulting, I delivered solutions tailored to different business needs, adapting to varied requirements and project contexts.
I aim to keep growing as a Full Stack Developer, deepening best practices, API design, application architecture and building maintainable, scalable solutions.
