About

Over the past nine years, I have had the incredible opportunity to develop my skills as a full-stack developer. I have learned how to integrate front-end and back-end development to deliver high-performing applications effectively. I am thrilled to be proficient in industry-leading frameworks such as React (with a focus on user-friendly and performant interfaces), Spring Boot, and .NET Core. These frameworks empower me to tackle complex projects confidently.

My passion for continuous learning drives me to explore new technologies and refine my skills actively, and I love every minute of it! I love documenting my learning journey and have a knack for turning fragmented data into valuable insights. I share these insights in detailed blog posts that I'm really proud of! This dedication to innovation ensures that I bring the latest knowledge to my recent project!

I believe that having a healthy work-life balance is essential for a happy and fulfilled life. I love spending time with my family and friends, playing badminton, and exploring new restaurants (I'm a big foodie!). These activities help me maintain a fresh perspective and inspire new solutions, contributing to my problem-solving abilities and creativity in amazing ways!
