Hi, I’m Versachios
I turn ideas into things that run.

A Vietnamese student working through competitive programming, web development.

Why this exists

This is a workbench, not a résumé.

I built this site as a place to keep the things I’m actually doing — projects that ship, problems I’m still stuck on, experiments that go nowhere, and the occasional idea worth writing down. It updates the way my understanding does: unevenly, and usually after something broke first.

    Primary School

    First contact with programming: Scratch and Python in class, C++ after class, and a slowly growing habit of finishing what I start.

Notes

01Learning how to code in Competitive ProgrammingCPSpent the whole summer to learn before anyone did, and i have never regret doing that <3.22 Jul 2025
02Preparing for the Competitive Programming contestCPI still remember the feelings when we all learning in the same room, the scent of coffe and snack. And somehow I did it.12 Dec 2025
03Preparing for the final contest.CPWe had about a month to prepare for the provincial-level competition for gifted students. During that time, we created wonderful memories, studying and journeying together through that final stretch.11 Jan 2026
04The day I was overcome with happiness.CPI performed quite poorly on the provincial gifted student exam. Yet, when the results were announced, I had just enough points—by a margin of 0.05—to secure an award. I became the only student from a standard class—competing at a higher grade level—to win an award in that provincial competition.09 Feb 2026
05Road to K81 ITCPI have worked through a great many entrance exam papers for specialized schools across various provinces. I have learned so much, and this marks a major step toward getting into the school of my dreams.01 Jan 2026
06Building HVTCoderProjectThen it comes to building my first website. At first, it was just a small idea — a place where I could practice, submit code, and learn from my mistakes. But as I kept working on it, HVTCoder slowly became something much bigger: a platform built around my journey in competitive programming. It is far from perfect, but it is the first project that truly feels like my own.08 Aug 2026
