Contact

Tell us what broke.

One of the four of us reads every enquiry. Replies inside two working days, Asia/Bangkok. If it is not our kind of problem we say so plainly and, where we can, point you somewhere better.

Scoping enquiry

Detail beats politeness. The most useful first message contains a symptom, its blast radius, and what you have already ruled out.

Availability

Two engagement slots open for Q4 2026.
Q1 2027 is waitlist only.

Discovery and second-opinion work can usually start inside three weeks regardless of the engagement queue.

Before you write

Four questions we will ask anyway.

When did it start?

An exact date beats "a while ago". Change logs around that date are usually where the answer is.

Who is affected?

All users, one region, one carrier, one client version. The shape of the blast radius names the layer.

What did you try?

Including the things that did not work. Especially the things that did not work.

What is the deadline?

Audit, contract, or launch. If there is no deadline, say that too — it changes the scope we propose.
