Where I started, what I do now

A student-run product studio that I help run and grow. I work most closely with one teammate, and the studio's products are divided between its members instead of being built by one person alone.

• CHNAI LAB is a small student-run studio — six members on its GitHub organization, where I am one of the administrators. We split the products between us rather than all working on the same one: my share is product direction, applied-ML planning, field validation, the evidence standards we hold our products to, and PhsarOS, the operations platform for small shops that I build myself.

• PhsarOS, my own product inside the studio, is deployed and publicly reachable: point of sale, inventory, customers, expenses, and a dashboard computed from real records.↗

• Chomkar OrderLoop and our Turing Hackathon Cycle 10 entry were team work, not solo projects.

• CHNAI LAB is a public student-run product studio with a published governance model (agent workflow, security policy, contribution rules); Chomkar is named there as a product track.↗

• Contributing product direction, applied-ML planning, field validation, and evidence standards across the studio's Cambodia-first experiments.

Runner-Up Award with the Chomkar OrderLoop concept as team CHNAI LAB: coordinating buyer demand and smallholder farmer commitments into one documented pre-harvest lot. The model is public at chomkar.com.

• The hackathon is a national program run by Techo Startup Center / Startup Cambodia.↗

Structured interviews with bok choy farmers in Kang Meas district, Kampong Cham, to test demand-visibility and coordination assumptions before building software.

• The team interviewed approximately 30 farmers; I contributed to interview design and analysis. Interview records are private.

The first competitive year: first in Grade 9 mathematics across the district and the province, and ten medals in national and international competitions — two golds, five silvers, and two bronzes among them.

The final school year: first at every local level, national runner-up in mathematics, Grade A in the Bac II, and four full scholarships.

I lead a small professional reading circle governed by a written handbook. Leadership rotates through weekly offices, and members are measured on what they produce — explanations, artifacts, applied experiments — rather than on pages read. These are the standards I set for the circle, not results it has reported.

• Wrote and maintain the circle's governing handbook — 42 pages, Second Edition 2026 — covering the constitution, the reading method, the AI-use policy, working templates, and a twelve-month book pipeline. It is reviewed quarterly and stays internal rather than published.

• Wrote the circle's AI-use policy: five rules binding on every member, including me — AI never replaces the reading, recall before assistance, AI as challenger rather than answer machine, first drafts authored by the member, and disclosure of AI's role in anything shipped. It is the same claim discipline this site runs on, written for a group instead of for one person.

• The circle grew out of a four-member reading club begun on 28 July 2026 and now runs live sessions under this handbook.

Back in the mathematics-competition world from the other side of the table: helping run the CIMOC Final Round in Phnom Penh and contributing to the Grade 11 examination paper.

• Assisted in organizing and invigilating the CIMOC Final Round (26 October 2025, SCIA, Phnom Penh) and contributed to writing and preparing the Grade 11 mathematics examination paper.

• The volunteer team was photographed together at the Final Round award ceremony.

Compiled, edited, and self-published six bilingual mathematics titles as First Editions (2026) under the CHNAI LAB imprint: matched Grade 6 and Grade 7 sets of an English–Khmer dictionary, an exercise book, and a full worked-solutions answer book — 1,780 pages in total, with original exercise questions and fully worked solutions, written for Cambodian students who study mathematics in English.

• Grade 6 set: an English–Khmer Mathematics Dictionary (240 pages), a Mathematics Exercise Book (595 original questions in six levels across twenty chapters, 260 pages), and a Mathematics Answer Book with a full worked method for every question (340 pages).↗

• Grade 7 set: an English–Khmer Mathematics Dictionary (488 pages), a Mathematics Exercise Book (572 questions in six levels, chapter by chapter, written against the Ministry of Education, Youth and Sport Grade 7 textbook, 156 pages), and a Mathematics Answer Book reprinting every question above its full worked solution (296 pages). All six books are free to download from the GitHub release.↗

• Produced with AI assistance, disclosed here under the same rule I apply to anything I ship: AI tools drafted the questions, worked solutions, and dictionary entries, and I reviewed, corrected, and approved the content before release.
