As the core web developer for codeslayer.tech, I was tasked with building the official digital gateway for the Code Slayer 2k25 Hackathon, a premier 36-hour national coding competition hosted at NIT Delhi. My mission was to create more than just an informational page; I engineered an immersive, high-energy web experience designed to captivate and mobilize India's brightest student innovators. The website was the central hub for the entire event, serving as the primary engine for driving registrations and communicating the high-stakes "Demon Slayer" theme. This platform was the single source of truth for all participants. I built it to manage everything from initial team registrations and idea submissions to detailing the six complex event tracks, including AI/ML, Web3, and IoT. The result was a dynamic, responsive, and compelling website that successfully converted nationwide hype into action, handling the traffic and logistics for over 1,170 registered participants and setting the stage for one of the year's most exciting tech battles.
