About Me
I'm Sanithu, a Computer Science student and builder focused on creating high-performance web applications, scalable systems, and startup-grade products.
I specialize in full-stack development, with a strong eye for clean UI, smooth animations, and performance first architecture. I enjoy taking ideas from zero to launch designing the interface, engineering the backend, and thinking through scalability, security, and user experience as a complete system.
Beyond code, I'm deeply interested in startups, product strategy, and long term wealth creation. I actively build projects, experiment with ideas, and refine my skills with the goal of becoming a world class engineer and founder.
I value discipline, execution, and craftsmanship. Whether it's software, fitness, or personal growth, I aim to operate at a high standard and improve every day.
Currently seeking internship and early career opportunities where I can contribute, learn fast, and build things that matter.
