Most people see a problem and find a tool.
I see a problem and build the infrastructure
that makes the tool unnecessary.

With 22 years of operational experience across supply chain, procurement, and logistics — I've lived inside the broken systems most people only read about.

That experience became the foundation. When AI emerged as a real engineering tool, I didn't just adopt it — I rebuilt entire workflows from the ground up.

Today I design and build production-ready AI systems across healthcare, enterprise automation, and beyond. The next frontier: medical-grade AIoT infrastructure for the next generation of patient care.

Procurement System

Public Procurement Act B.E. 2560 Compliance Engine

Government paperwork that depends on repetitive copy-paste creates frequent errors. This system reads PDFs automatically with OCR and fills every form correctly under Thailand's Public Procurement Act B.E. 2560.

Logistic Strategic Engine

Real-time Route Risk Intelligence

Route intelligence is scattered, forcing teams to judge safety by hand. This system combines weather, geopolitics, and natural-disaster signals and scores each route's risk in real time.

GreenCargo

Carbon Credit for Transport

EU exporters lack carbon reports that meet TGO standards. This system calculates CO₂ automatically, generates GHG reports, and alerts when vehicles need service to cut fuel waste.

PRISM by SRAG

Real Estate AI Lead Engine

Buyers walk away when they cannot find the right project. PRISM uses an SRAG engine to match customer intent to the right developments and nurtures not-yet-ready leads into future buyers.

Universal ERP

Modular ERP for SME

SMEs cannot afford enterprise ERP stacks. This platform delivers Finance, HR, Stock, Procurement, and Marketing in one place — pick the modules you need, with industry templates for restaurants, clinics, and beauty.

QA LAB

AI-Powered Product Readiness

QA teams lack readiness tools before launch. QA LAB simulates user personas and load scenarios, analyzes with ML, and reports weak points before production fails.

SynthComm

Thai Synthetic Data Factory

Training AI needs volume, but real conversation data collides with PDPA. SynthComm generates high-fidelity Thai synthetic data through a multi-agent factory with automated monthly ML retraining.

Content Creator

One-Stop Short Video & Podcast

Creators juggle multiple apps to ship content. This platform finishes in one place: Script → TTS → MP4 (9:16) — for TikTok / IG / X, plus podcasts in Northern, Isaan, and Southern Thai dialects, Vietnamese, and Indonesian.

MyClaw Music

Human-Soul Music Demo Tool

Songwriters lose time coordinating lyricists and composers. MyClaw helps draft demos that keep the author's voice — not fast, soulless AI tracks.

NETR

Mental Health Behind the Stars

People under life stress often seek relief through astrology. NETR is an astrology AI with mental-health counseling behind the scenes — supporting depression, aging, and youth without making users feel like they are "asking for help."

Healthcare is broken
at the infrastructure level.

A patient's health data is scattered across multiple devices, multiple apps, multiple Bluetooth signals — with no central system that aggregates, analyzes, and delivers it in real-time. This isn't a software problem. It's an infrastructure problem.

Bluetooth Collision
One patient wearing 3–5 devices means 3–5 competing Bluetooth signals. In a ward of 100 patients, signals collide — data gets lost before it reaches the doctor.
Fragmented Data
Glucose in App A. Heart rate in App B. Brain activity in App C. Physicians must context-switch across multiple platforms just to understand one patient.
UX Complexity
Elderly patients must re-pair devices every time a sensor is replaced. That friction kills compliance — and breaks the continuity of data that clinical decisions depend on.
The Solution

3-in-1 Medical Wearable Ecosystem

One device. One Bluetooth signal. Complete physiological data.

BREAKTHROUGH 01
Magnetic Pogo Pin Connection

The CGM Disposable Pad connects to the Core Unit via Magnetic Pogo Pin. Replace the pad without re-pairing. Seamless reconnection — zero friction for the patient.

BREAKTHROUGH 02
Single Bluetooth Source

One patient = one Bluetooth signal from the Core Unit only. Eliminates signal collision in clinical environments and prevents misidentification via Unique Device ID.

BREAKTHROUGH 03
Medical Internet Architecture

All sensor data converges in a unified platform. Physicians get a real-time full picture of every patient — laying the foundation for a true Medical Internet.

The goal is not a better wearable.
The goal is to build the
Medical Internet.

An infrastructure that connects every human's health data — the same way the Internet connected the world's information. That is the legacy being built.

Let's Align

I've shown you
what I'm building.
What's your vision?

11 production systems is the proof. Not a pitch deck — actual infrastructure, built and shipped.

I'm not looking for someone who fits a job description. I'm looking for someone with a vision of their own — so we can tune until it aligns.

Whether you're a builder, an investor, a domain expert, or simply someone who sees the same problem — let's talk.

You see a problem others overlook
There's a pain point in your industry that nobody has truly solved yet. Tell me about it — we might build it together.
You have the domain. You need the technology.
Deep expertise in your field, but no clear path to building the system around it. That's exactly where I come in.
You have the vision. You're missing a piece.
The big picture is clear — but you haven't found someone who speaks both business and technology fluently. Let's tune until it fits.
You simply see the same thing.
No agenda required. You just believe that infrastructure changes the world more than any single feature ever will. That's enough.
Available for the right conversation

Let's build
something real.
Not someday.

If you've read this far, you're probably not here by accident. You have a problem, a vision, or a question. That's the only qualification needed.

Reach me directly
What to expect
I read every message personally
No auto-replies. No assistants. Just me.
I respond within 24–48 hours to every serious inquiry.
If your message is vague, I'll ask a question — not ignore it.
The best conversations start with a single honest sentence.
Not sure what to say?

Start with the problem you're trying to solve. One paragraph is enough. The rest we figure out together.
