About Me

About Me

My Photo
Personal Info

My journey didn't start with luxury or a shiny office — it started like any kid from the countryside, just trying to survive. I began with small steps, building simple websites for a race track in Buriram

From there, I moved into the world of commerce in Bangkok — starting with support and small development tasks. Soon after, I joined a full dev team — building systems end to end while still supporting what I created. In that arena I sharpened my skills, learned to move as part of a pack, and carried projects from idea to delivery. Those years forged my foundation as a developer, giving me the scars and the craft I still carry today.

Then life hit me with something heavier than deadlines — LOVE. That love became the reason that drives me to better than I was before. I traded the comfort of in-house work for the chaos of contracts, choosing independence over certainty.

Now, I roam from project to project, no pack to rely on — only my own grit and skill. Through fire I survive, from ashes I rise — and rise from the ashes again. I build, I break, I rebuild — faster, sharper, tougher. I'm not here to just write code. I'm here to hunt down problems, tear them apart, and forge solutions that endure.
