πŸ‘‹ Hi, I'm ROtHi

πŸš€ Backend Engineer | GenAI Architect | Scalable Systems Builder

Backend Engineer with 5+ years of experience designing and building scalable, high-performance systems across EdTech, E-commerce, and News Portal platforms.

Currently at 10 Minute School, working across core backend systems and AI products β€” building architectures that reliably serve 5K+ concurrent learners through TenTen AI.

In the second half of 2025, I transitioned into owning end-to-end GenAI product architecture β€” designing, building, and scaling LLM-powered systems from scratch to production.

I also lead the architecture and development of ClassRoomOS, a platform powering large-scale offline education centers.
