About

I’m a Full Stack Developer with 1+ year of professional experience and have been focused on learning web development since 2021.
Over the past 4 years, I’ve worked with HTML, CSS, JavaScript, and TypeScript.
I’ve explored various frameworks and technologies, building projects with vanilla JS and Angular, and completing courses in Node.js and backend technologies.
In 2022, I successfully completed an internship at EPAM Systems in Gdańsk, where I studied ServiceNow development based on JavaScript.
In 2023, I focused on React, and in 2024, I transitioned into a Full Stack Developer role.
Currently, I work remotely in a team on a project based in Argentina that helps Spanish-speaking users schedule and attend online sessions with psychologists.
I contribute to both frontend and backend tasks, with strong attention to usability, code quality, and testing.
