Andriy Lutsenko
REACT NATIVE/React DEVELOPER

My name is Andrew(Panda as nickname), a Senior React Native Developer with
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.
