Hi, I’m Chathusha Mendis. I’m a Trainee Full Stack Engineer at AxisTech with a passion for solving complex puzzles. From mastering the intricate ragas of Hindusthani classical music to calculating the perfect move on Chess.com, I thrive on strategy and precision. When I'm not building applications, you’ll find me sharpening my security skills on HackTheBox or exploring new worlds as a gamer on Steam.
