What we've learned from taking over and maintaining real systems — not trends we read somewhere else.

A prototype built with AI tools runs and demos fine, but when it's time to go live, many owners rush to add features and end up with something no one dares touch. This article defines maintainability in four plain terms — understandable, changeable, observable, recoverable — and gives the order to fix them in.
Technical Sharing
The website still runs, but the domain, hosting, and source code are all registered under a vendor you can no longer reach — so you can't change, migrate, or hand anything off. This article covers how to trace all three back by checking registration, billing, and the repository, what to do if you can't get them back, and why the first move afterward is a health check.
Industry Trends
"You haven't even looked, and you're saying you can't quote a price?" often makes people uncomfortable, but drawing the line upfront saves time for everyone. This article lists, as-is, the four situations we take and the five we don't, explains the reason behind each one, and explains why we always refuse to quote a price without a health check first.
Industry Trends
"I'll just watch the server myself" saves you a budget line, not time. This article skips market pricing and lists exactly what hosting (monthly), monitoring (weekly), and security updates (quarterly) require and roughly how long each takes, so you can add it up, multiply by your own hourly rate, and compare that against a basic maintenance plan.
AI Research
You tell AI to fix A, it breaks B; fix B, and A breaks again, until the product ends up in a state of "it works, but nobody dares to touch it." This article explains, in plain terms, why this happens: there's no list of what to recheck after a change, and automated testing is the machine version of that list. It then shows you where to start: the paths that would cost you money if they broke.
Technical Sharing
When an engineer leaves saying "it's all in the code," the next person is left doing archaeology. This article doesn't call for a thick manual, just five one-page documents: where the system runs, how to deploy, where the data is, who can log in, how common issues are handled, and how to keep it from going stale.
Industry Trends
Sales wants A, support wants B, and you want C — the longer the request list, the harder it is to prioritize. This article gives a method anyone can use without technical knowledge: two axes, impact and cost, plus a third question — who looks after it once it's done — walked through with five common requests in a table.
Industry Trends
The maintenance fee you save by thinking "it still works" isn't saved — it's deferred. This article walks through three scenarios — a day of downtime, a data breach, and a system you can no longer change — so you can plug in your own company's numbers and compare them against the monthly maintenance fee.
We build long-term relationships with a select few partners worth going deep with.
