I’m Aakash, and I built Contest Clocker out of personal frustration. I kept missing competitive programming contests during my interview prep. I’d check Codeforces or LeetCode, make a mental note… and still forget 😅 I wanted a tool that would: Show me all upcoming contests in one place Send reminders before they start Let me add contests directly to my calendar I built it as a Chrome extension using Vite and React. Along the way, I learned a ton about Google Calendar APIs, OAuth verification, and designing something clean and fast enough to live in a browser pop-up. Now it’s become something I use daily, and I hope it helps others stay consistent with their practice too! Would love to hear: 👉 What platform or feature would you like next? 👉 Do you track contests manually or use something else? Excited to hear your thoughts! 🚀
