Would love to hear your feedback, suggestions, or ideas for new features! 🚀</p> <h1> Codeforces #CompetitiveProgramming #WebDevelopment #NextJS #TypeScript #TailwindCSS #FrontendDevelopment </h1> webdev react nextjs frontend Jubayer Ahmed Fri, 31 Oct 2025 06:59:12 +0000 https://forem.com/jubayer_ahmed_d082891971b/built-cf-ladder-a-web-app-to-make-codeforces-practice-smarter-sort-filter-and-track-problems-hc2 https://forem.com/jubayer_ahmed_d082891971b/built-cf-ladder-a-web-app-to-make-codeforces-practice-smarter-sort-filter-and-track-problems-hc2 <p> </p> <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__cover"> <a href="https://cf-ladder-pro.vercel.app/" class="c-link align-middle" rel="noopener noreferrer"> <img alt="" src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fres.cloudinary.com%2Fddysafn4k%2Fimage%2Fupload%2Fv1761489634%2Fcoding_8061324_p0o1nb.png" height="auto" class="m-0"> </a> </div> <div class="c-embed__body"> <h2 class="fs-xl lh-tight"> <a href="https://cf-ladder-pro.vercel.app/" rel="noopener noreferrer" class="c-link"> CF Ladder – Smart Codeforces Ladder &amp; Problem Tracker </a> </h2> <p class="truncate-at-3"> Practice Codeforces problems smartly, track progress, and improve your rating with CF Ladder – your go-to CP companion. </p> <div class="color-secondary fs-s flex items-center"> <img alt="favicon" class="c-embed__favicon m-0 mr-2 radius-0" src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fcf-ladder-pro.vercel.app%2Ffavicon.ico%3Ffavicon.0b3bf435.ico"> cf-ladder-pro.vercel.app </div> </div> </div> </div> <br> <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__cover"> <a href="https://github.com/jubayer17/cf-ladder" class="c-link align-middle" rel="noopener noreferrer"> <img alt="" src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fopengraph.githubassets.com%2F67be238486ad62937baafefccabc3f96ffe86090de15dfa0c0973bb156691a72%2Fjubayer17%2Fcf-ladder" height="auto" class="m-0"> </a> </div> <div class="c-embed__body"> <h2 class="fs-xl lh-tight"> <a href="https://github.com/jubayer17/cf-ladder" rel="noopener noreferrer" class="c-link"> GitHub - jubayer17/cf-ladder: A web-based platform that helps users practice Codeforces problems efficiently through a structured ladder system.
