7 years of experience in building and optimizing mobile applications. My career began in 2017, and since then, I have been dedicated to mastering the technologies surrounding React Native to deliver efficient, high-quality mobile solutions.
Over the years, I've led several projects from inception to deployment, working closely with cross-functional teams to ensure we deliver products that not only meet but exceed user expectations. My technical expertise lies in JavaScript and React, and I'm proficient in tools like Redux for state management and little bit in Node.js for backend services.
One of my key strengths is my ability to troubleshoot and optimize existing applications, which has resulted in significant performance improvements in several projects. For example, in my previous role at Lead/Front-end developer, I spearheaded a project that improved application performance by 40% through meticulous code refactoring and adopting newer, more efficient React Native libraries.
I'm also passionate about sharing knowledge and have mentored junior developers, helping them grow into competent professionals. As I look to continue my career, I am eager to join a team that challenges the conventional and pushes the boundaries of technology in mobile development.
