Full-stack product builder and mathematics educator based in Cambodia. I ship practical platforms for classrooms and academic institutions.
Open to education and digital-product collaborations
3 platforms in production
Counted from published content on this site.
Featured case study
A bilingual academic repository for Phnom Penh Teacher Education College — books, theses, publications and curated learning paths, readable online, installable as an app and searchable in Khmer and English.
Academic material at a teacher-education college is scattered: print on shelves, syllabuses on personal drives, theses bound once and rarely opened again. A student who cannot find a text is in the same position as a student for whom it does not exist.
One bilingual site carrying the whole collection — digital and physical, the college's own work and hosted material — with each item's rights stated on the item. Readers browse and search without an account; an account adds saved lists and offline reading.
The platform is live at library.ptec.edu.kh and serves the college's collection publicly in Khmer and English. As of 31 July 2026 it publishes 114 digital resources, 7 active physical catalogue records and 4 learning paths — figures the site itself reports in its public llms.txt.
Selected work
Real systems, in production, used in a teacher-education context. Each one has a full case study.

How the platforms fit together
Each platform solves its own problem, and each one is more useful because the other two exist. Together they cover the teaching, the material and the infrastructure underneath both.
How the work happens
Most of these products started as something that did not work in a real classroom or a real library. This is the route from noticing that to shipping something that fixes it.
Tutoring, student teaching and school placements — where the problems are met first, as the person responsible for solving them that day.
Teacher workflows that take too long, resources nobody can find, academic material with no consistent home. Written down before anything is designed.
Who it is for, what they already do, and the smallest system that would help. Information architecture, workflows and interface design.
Building it: data model, permissions, authentication, storage and delivery. Bilingual from the first screen rather than translated afterwards.
The output — platforms teachers and students can actually reach, and authored mathematics material that goes into them.
Education and journey
Planned and delivered primary mathematics lessons while developing practical skills in classroom management, student engagement and formative assessment.
Designing and developing practical digital platforms for teachers, students and academic institutions, including KruSmart, PTEC Digital Library and PTEC Storage.
Studying primary teacher education through the 12+4 programme, with a focus on pedagogy, mathematics instruction, lesson planning, student assessment and classroom practice.
I am currently studying as a student teacher in the Primary Teacher Education (12+4) programme at Phnom Penh Teacher Education College. My studies focus on pedagogy, lesson planning, student assessment, educational research and primary-school classroom practice.
I am currently pursuing a bachelor’s degree in Mathematics at Khemarak University while completing my teacher-education programme at PTEC. My studies strengthen my knowledge of mathematical reasoning, analysis, algebra, geometry and related scientific subjects.
And 5 more on the full experience page.
I use LaTeX to produce clean, accessible mathematics resources for Cambodian students. Precision in code, precision on the page.
