Built a free, no-login web platform that curates and organizes quality YouTube tutorials for students struggling to find structured learning content. The platform aims to reduce the time wasted searching and provide an easy-to-navigate, distraction-free experience. As a student from Bihar, I noticed many learners in my community faced this problem, so I created MuftSkill to bridge this gap and help them access reliable tech education resources quickly. 💡 Key Features: Built a clean, slider-based UI using HTML and CSS (90% of the code) Added interactivity with basic JavaScript (with help from my brother) No backend: instant access without sign-up — learn and go! Focused on creating a distraction-free, structured learning experience 📍 Tested at KYP Centers (Kushal Yuva Program), Bihar: I introduced MuftSkill to students at local government skill development centers. Currently, live and actively used at KYP Centers, helping real students learn faster without wasting time searching. 📱 Mobile Optimization (In Progress): While the site works well on desktops and laptops, I’m currently optimizing it for mobile users to ensure smooth access on all screen sizes. 🎯 Skills Used: HTML, CSS, JavaScript, UI/UX Thinking, Problem Solving, Basic Version Control (GitHub) 🚀 Goal: To use tech to make learning simpler, smarter, and more accessible — and to grow through internship opportunities where I can contribute to real problems and learn from real teams.
