YooBees — The Platform I Built
A Real-Time Learning Platform
YooBees is a full-stack web application I designed and built from scratch to serve the Masters of Business Informatics (MBI) programme at Yoobee Colleges. It replaces static slide decks and paper registers with a live, interactive, data-driven classroom experience.
Every feature was shaped by a real classroom problem — from fraudulent attendance submissions caught by three detection algorithms, to students competing on SQL queries in real time.

One-tap Attendance
Students check in with a single tap. Three detection algorithms run in real time to flag dishonest submissions: shared-IP clustering (multiple students on one device), GPS outlier detection (coordinates >500 m from campus), and a rapid-submission window (check-ins within 30 s of session open).
Live Playground
An in-browser code execution environment embedded directly in lectures. Students write and run SQL, Python snippets, and pseudocode without leaving the platform — and I can see their output live.

SQL Race
Students race around a virtual track by solving SQL challenges in sequence — SELECT → WHERE → JOIN → GROUP BY → ORDER BY → HAVING. A live leaderboard drives friendly competition and keeps engagement high across 228 students.
Quiz Badges
Over 100 MCQ questions across all three MBI courses. Students earn badge tiers as they progress, with instant feedback and explanations. Results feed directly into the lecturer analytics dashboard.
Daily Match
A daily collaborative challenge pairs students across cohorts to solve a shared problem together. Designed to build cross-cultural communication skills in an international classroom spanning 24 countries.
Cohort Analytics
A lecturer-only dashboard surfaces attendance trends, quiz completion rates, country-level engagement, and fraud alert history — giving me a full picture of each cohort without manual data wrangling.
