About
I'm a Software Engineer at TOPPAN Ecquaria, reading a Master's in Computer Science at Georgia Tech, with a strong foundation in algorithms, data structures, and software development.
Through hands-on projects I've worked across web development, machine learning, and cloud solutions, turning complex challenges into clean, functional software.
Always curious and committed to continuous learning. I look forward to connecting with like-minded engineers and exploring what's next in tech.
