I build products — and the team that builds them.
Most orgs split product, engineering, and data into separate teams — then wonder why building is slow. I lead one AI-first team where they're a single craft, and I still build alongside them. 10+ years, still shipping.
What I Do
Product Builder
I ship product end-to-end — not just the spec.
Computer Engineering from Chulalongkorn. I've been a full-stack engineer, engineering manager, and product leader — so I prototype fast, spec precisely, and build when it's faster to build than to explain.

Building the Team
I build the team that builds the product.
As Head of Digital Platform at Juzmatch, I lead an AI-first team where dev, product, and data are one craft — not three departments filing tickets at each other. 10+ years leading PMs and cross-functional teams across marketplace and fintech.

Data Foundation & Analytics
I build the data infrastructure companies need before they know they need it.
From raw Excel files to a fully self-serve analytics platform — in 10 weeks. I architect and implement the data foundations that let teams answer their own questions without waiting on anyone.

AI & Automation
AI isn't just a feature I build — it's how I operate.
Personal automation workflows, LLM-powered tools, and team-level AI adoption. I help people and organizations stop spending time on things that shouldn't require human attention.

Now Building
Claude Code skills for making a PM’s life easier — and a lot more fun.
An open collection of agent skills I use daily: writing, research, automation, and product workflows. Constantly growing as I find new things that shouldn’t require human attention.
github.com/psisquare/skills →Personal OS — an AI assistant that knows my world and does the work, not just answers.
Most AI is a brilliant brain in a jar: it answers, but it doesn’t know your context or touch your tools — so you lose hours re-explaining and doing grunt work by hand. I gave Claude Code a brain (my world as structured memory) and hands (real tools via MCP); this is a scrollable walkthrough of how it fits together.

What Drives Me
I run ultras — sub-3 marathoner — and track splits and HRV the way I'd run a product review. I build the tools I personally need, because if I'm doing something twice I'm already thinking about how to stop doing it myself. And what I love most about building is the moment something complex becomes simple and inevitable — when the tool just does what you meant.
