Work
Everything below is a system that is running right now. None of it is a screenshot or a mockup. The first three you can start from this page without going anywhere else, and for the other four the full source code is public on GitHub for you to read.
I built every project below on my own, each one inside a single day, because I set the brief myself, I knew the answer before I started, and nobody had to sign it off. Client work takes weeks for a different reason. Most of that time does not go into writing code. It goes into understanding how your team actually works, testing against your real data, fixing the parts you get stuck on, and handing it over so your people can run it without me. Those last two are what I charge for, not the number of lines of code.
Try these right on this page
Press the button and the real app loads into the frame below. It works the same as opening that site directly. On a phone the button opens a new tab instead, because these apps were built for a desktop screen.
DocChat
Point it at any web page and ask a question. It goes and reads that page itself, summarises it, and turns it into a list of things to do, showing you where each part of the answer came from.
GradeLens
A school grading system that follows the real Thai rules, including the 80 percent attendance rule that overrides the score every time. Teachers enter a whole class of marks on one screen and take daily attendance. The full source is public, with 26 tests covering every grade boundary.
LedgerLens
An AI bookkeeping check that reviews its own work. It does more than sort transactions into categories. It points at the rows that look wrong and should be read by a person, and gives its reason by quoting the source rows it read.
InsightForge
Upload a data file and the AI asks its own questions of it, finds what stands out, and writes it up as a report you can actually read, instead of you having to know what to ask first.
Work a client uses every day
The client agreed to let me describe this without naming anyone, so the company, the hotels, and every business figure are left out. What remains is what the system does, and one line in her own words.
An automated morning report for a seven-hotel group
Revenue director, hotels in two countries · running daily since July 2026
Every morning used to start by logging into each hotel one at a time, collecting the numbers, and writing a summary for the executive above her. It was the same work every day, and it had to be finished before the real analysis could begin. The system I built logs in on its own, captures each hotel's report along with four forward-looking views, and runs the European property on an afternoon schedule so it lands in that hotel's morning. It then turns the raw figures into plain-language notes she can forward as they are, and has AI analyse both each hotel and the whole portfolio, looking only forward. Every credential lives in the Windows credential store and none of them appear in the code, and each captured image is checked so no other hotel's data can leak into a report meant for one owner.
Work is easier and much faster now. Mornings are not a rush the way they used to be, because the automation handles it for me every day.Revenue director, seven-hotel group · translated from Thai
The code is open to read
These four cannot be embedded in a page. One is a bot inside Slack, one is an app you install on a phone, and the rest run in a terminal. The source code is public for all of them, so you can go in and read how they are written.
Claude Assistant for Slack
An AI assistant for the workplace. It answers from your company documents and names the source file behind every answer.
ReceiptLens
An app that reads receipts through the camera and checks the totals. It all happens on the phone, and no data is sent anywhere.
SlipGuard
A PromptPay gateway that shows a QR already carrying the order total, takes the transfer slip, and refuses a slip that has already been used on another order.
RaidPress
A WordPress plugin that checks whether anyone has changed files they should not have. Every core file is hashed against the official wordpress.org checksums, then wp-content is walked for the constructs real plugins never use.
raidscan
A fast network scanner that keeps the history of every scan, with a dashboard that shows results as they come in.
promptraid
A tool for attacking AI systems on purpose, following the OWASP LLM Top 10. I run it against a bot before your customers get to it.
Want something like this in your business?
Tell me how the work gets done today and where it costs you the most time.
I send back the scope and the whole price within 1 to 2 business days, and there is no call to sit through.
Everything you get is in English: the scope document, the contract, the handover pack and the comments in the code. After handover you have 60 days to come back to me with questions. Once the scope is agreed I send an invoice with the payment instructions on it.
