PolandWhat I'm looking for
I am a Senior React Developer with a Master of Science in Automatic Control and Robotics. Over the past several years, I have honed my skills in developing web applications using React, Typescript, and Next.js, primarily in agile environments. My experience spans various industries, including EdTech and FinTech, where I have successfully led projects and collaborated with international teams.
At Binogi, I am responsible for creating EdTech web applications, focusing on architecture and code quality through rigorous code reviews and unit testing. Previously, at Danger Farms, I played a pivotal role in a FinTech project, where I not only developed applications but also took on leadership responsibilities in daily operations. My technical toolkit includes modern frameworks and libraries such as GraphQL, Chakra UI, and Ant Design, which I leverage to deliver high-quality software solutions.
