Final-year software engineering student building scalable web and real-time backend systems.
VietnamWhat I'm looking for
I’m a final-year Software Engineering student with a strong foundation in building scalable web applications and real-time communication systems. My experience comes from academic and personal projects where I focused on backend services and reliable system behavior.
In TicketBox, I designed a Modular Monolith architecture using local ACID transactions to avoid Saga complexity. I built a waiting room and queue system with Redis to regulate traffic surges—handling up to 1,000 concurrent requests during peak testing, reducing server crashes to 0%. I also integrated Redis for rate limiting and request idempotency to prevent duplicate payments and API abuse.
In my other projects, I implemented real-time features such as teacher–student chat and real-time assignment notifications, using Firebase Cloud Messaging for delivery with under 500ms latency. I also implemented RBAC with custom claims and integrated Agora for stable real-time sessions (up to 50 concurrent users), including session lifecycle handling and automated completion triggers.
