Transactional Engine · 0% Overbooking · 99.98% Uptime
When hundreds of high schoolers race to book popular electives simultaneously, standard web forms suffer from race-condition overbooking and fail to validate cross-group dependencies or shared cohort pools.
Built a custom Node.js + Socket.IO server wrapping Next.js 16 and Prisma ORM with PostgreSQL Serializable transactions. Every enrollment atomically verifies live cohort capacity and broadcasts instant WebSocket quota updates.
100% elimination of seat overbooking under concurrent load, real-time WebSocket seat counters, and automated 3-stage academic resource & teacher tariff modeling.
B2B curriculum & elective scheduling platform for high schools and universities managing complex track rules, laboratory constraints, teacher tariffs, and competitive real-time seat quotas.
Key Technical Capabilities
