The problem
Placement cells had no reliable way to see how students were actually practising. Data lived across four judge platforms and was collected manually through spreadsheets each semester.
What we built
CodeTracker syncs profiles from LeetCode, Codeforces, CodeChef and HackerRank into one multi-tenant workspace per college, layers on internal contests with Judge0 execution, and gives faculty ranked, filterable dashboards.
Key capabilities
Cross-platform sync
Scheduled ingestion of four judges with Redis caching to stay inside rate limits.
In-house contests
Judge0-backed execution with live leaderboards and per-problem scoring.
Multi-tenant by design
Each college gets isolated data, branding, batches and faculty roles.
Production deployment
Dockerised services behind Nginx with Redis queues and zero-downtime releases.
