With 4 years of professional experience, I specialize in backend development but have basic proficiency in front-end technologies, particularly Angular, and experience in DevOps on Windows Server. Currently, I work as a back-end developer on a Digital Advertising project, where I also support front-end development with ReactJS. I am always eager to adopt new technologies as needed.

I led a team of 8 developers, ensuring successful feature delivery and resolution of production issues. My leadership involved managing tasks, prioritizing work, guiding the team through bug fixes, deployment optimization, and server performance improvements, as well as identifying and mentoring talent for the sub-leader position.

With my skills, leadership experience, and proactive learning attitude, I am confident I can contribute to your company's success.
