Backend Engineer  ·  Security Researcher  ·  Reverse Engineer

I build robust systems, dig into how software works under the hood, and create tools at the intersection of security and engineering.

Backend engineer based in
Chiang Mai, Thailand

CAMT DII at Chiang Mai University with a focus on backend systems, security research, and reverse engineering. I work across the full stack of a problem — from low-level bytecode analysis to building production APIs and AI-driven pipelines.

I'm drawn to hard problems: compilers, obfuscation, binary analysis, and systems that need to be both fast and correct. Outside of that, I build practical tools that solve real-world problems.

Selected Projects

Rust Lua LZMA

Reaper Obfuscator

Production-grade Lua 5.1 obfuscator built in Rust using a Luraph-style architecture. Compiles source to bytecode, LZMA-compresses it, Base85-encodes the payload, and wraps everything in a self-contained Lua loader. Ships with a web UI backed by a Monaco editor.

Python YOLOv8 SQLite

AI Vehicle & People Counter

Real-time AI detection system using YOLOv8 to count vehicles and people from live camera feeds. Features a modular pipeline registry, face detection engine, crypto-backed local storage, and an event system for downstream integrations.

PHP AI Maps

AI Camera Dashboard

Web-based CCTV monitoring dashboard built for Chiang Mai Province government. PHP backend with webhook integration, CSV export, and an interactive map interface for managing and tracking distributed camera infrastructure.
