Plans your daily DSA and pings you on Telegram before the streak breaks.
Tech Stack
Next.js 14, TypeScript, MongoDB Atlas, Telegram Bot API, Firebase Auth, Cron
Description
A full-stack application that helps users protect their LeetCode streak. Users connect a LeetCode username, plan daily DSA questions, set a reminder time, and receive Telegram alerts while planned work is still pending. It pulls a profile card with streak, solved count, and difficulty breakdown, and auto-detects completed questions from recent accepted submissions. The planner supports a question bank with topic presets, CSV, text, and public Google Sheet imports, and a weekly plan generator. A progress calendar tracks planned, completed, pending, and missed questions, with analytics for total solved, weak topics, and missed days.
My Role
- Built the application on the Next.js 14 App Router with TypeScript, Tailwind CSS, and MongoDB Atlas via Mongoose.
- Integrated the Telegram Bot API for reminders and implemented bot commands for checking the day’s plan, marking questions done, and pausing alerts.
- Implemented auto-detection of completed work by reconciling planned questions against recent accepted LeetCode submissions.
- Built the daily and weekly planner with a topic-based question bank plus CSV, plain-text, and public Google Sheet import paths.
- Developed the progress calendar and analytics views covering planned, completed, pending, and missed questions, and weak-topic detection.
- Added authentication supporting LeetCode ID, email, and password alongside Google sign-in through Firebase, with scheduled jobs driving alert delivery.
