About Me
Passionate about crafting exceptional digital experiences
Hello! I'm Shashith Rashmika
I'm a passionate BSc. Information Systems undergraduate at UCSC with a strong focus on full-stack development. I love building innovative web applications that solve real-world problems using modern technologies like React, Next.js, and Node.js.
My journey in tech began with curiosity about how applications work, which evolved into creating production-ready systems. From building social platforms to AI-powered solutions, I enjoy every aspect of the development process - from UI/UX design to backend architecture.
I believe in continuous learning and staying updated with the latest technologies. Whether it's implementing machine learning models, real-time chat systems, or responsive modern UIs, I'm always excited to take on new challenges and push my boundaries.
