Helper CTO Series 25 | Why We Sometimes Recommend a Rebuild Is Actually Cheaper

恩梯科技 2026-10-12 587

"A rebuild is actually cheaper" is the hardest of the three health-check conclusions to write, since it means most of the original investment has to be written off. This article honestly lists the four situations where we reach that conclusion, what to preserve in a rebuild — data, process, accounts — and why recommending a rebuild doesn't mean you have to hire us.

Helper CTO Series 21 | Can't Find the Original Vendor: Getting Your Domain, Hosting, and Source Code Back

恩梯科技 2026-10-08 184

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.

Handing a system to a new team is unsettling when you're afraid you'll pay and see nothing happen.

Before handing over the code, what an owner most wants to know is "what exactly are you looking at." This article spells out the four areas of a system health check and the three things actually reviewed in each, plus the process: a 60-minute meeting, no production credentials needed, a one-page report, and one of three conclusions.

Helper CTO Series 05 | Nobody Dares Touch This System — Save It or Rebuild It? Four Checkpoints

恩梯科技 2026-09-22 390

A system that's been called both "don't touch it" and "beyond saving" shouldn't have its fate decided by gut feeling or by whoever wants the rebuild contract. This article gives four checkpoints: is it still readable, can the data be exported, can the architecture hold for two more years, and is fixing versus rebuilding really the same math — each with signals pointing toward saving it or toward rebuilding.

Helper CTO Series 02 | Your Engineer Left and the System's Still Running: 12 Things to Get Back First

恩梯科技 2026-09-19 416

After an engineer leaves, a system keeps running and most owners choose not to touch it — until a credential expires, a hosting payment fails, or a vulnerability gets exploited, and only then do they find the password isn't even in the company's hands. This article lists 12 items to recover first, three ways to proceed when they're out of reach, and the first thing to do once you get them back.
