As a senior frontend engineer at Buzzcast, I played a key role in the development of the company's innovative in-app chat feature, custom video player, and seamless Zoom integration. From the very first day of the startup, I was heavily involved in the building process, utilizing my expertise in technologies such as React, Redux, AWS, and GraphQL. My responsibilities also included mentoring junior developers, writing tests to ensure code quality, and working closely with the rest of the team to deliver a top-performing product. My experience and skills helped drive the success of Buzzcast and contributed to its growth as a leading player in the industry.
