I'm Tusar,
I build to scale.
I'm a MERN stack engineer with 2+ years of experience and a track record of shipping 100+ real-world products. From complex SaaS ecosystems to high-conversion e-commerce, I bridge the gap between heavy-duty engineering and seamless user experience.
Currently refining core system internals at Codecrafters. My focus is on the architecture that lasts: tight feedback loops, clean state management, and code that stays maintainable long after the first commit.
