I teach in Singapore and build AI for how students learn and how teachers assess.

Now

Teaching at Riverside Secondary School. Running Riverside Sec Oral Conversation for English, Chinese and Malay oral exams across the school, and building RSS Feedback as a Socratic AI tutor for our math students. Writing here about what I am learning along the way.

Selected work

• Riverside Sec Oral Conversation Live at school

  AI oral-exam grading for thirteen SEAB exam levels across English, Chinese and Malay. Students record in the browser; the system transcribes, grades against the rubric, and returns feedback in minutes. The teacher remains the final authority on every published mark.

  
• RSS Feedback Live at school

  A Socratic AI tutor for Singapore secondary math, aligned to SEAB syllabuses. Students draw their working on an iPad; the AI nudges them toward the answer instead of giving it; teachers assign, review and override marks.
