Software Engineer, Open Source Enthusiast, and a lifetime learner. I love to build things that solves problems and make people's life easier. Great to see you here! :)
About Me
Software engineer with 3+ years of experience building web apps—mostly frontend, but I tinker with the backend too. I love solving problems and help people through code. When I’m not coding, I’m probably geeking out over anime or mechanical keyboards. Always down to chat about programming, problem-solving, or anything nerdy! :)
