About

I’m a Full-Stack Developer with 8 years of experience specializing in modern web technologies and cloud solutions. Over the years, I have developed a strong skill set in technologies like Node.js, React.js, MySQL, MongoDB, Golang, AWS, Microservices, Docker, and Kubernetes. My expertise lies in designing and building scalable, efficient, and maintainable applications, with a focus on performance, user experience, and security.

I have had the opportunity to work on a variety of challenging projects across different industries, which has helped me gain deep sector knowledge and the ability to adapt quickly to new tools and environments. What sets me apart from other developers is my sense of commitment and problem-solving ability. For example, during my time as a Senior Developer at Cisco, I worked on real-time client support systems where I had to swiftly resolve critical issues without compromising on correctness, ensuring high-quality solutions under tight deadlines. This experience honed my ability to stay calm under pressure while delivering results that clients can rely on.

My diverse experience in both front-end and back-end development, combined with my passion for tackling complex problems, allows me to approach projects holistically and ensure every part of the system is finely tuned to meet client expectations.
