Help for vibe coders

Keep vibing,
vibe with confidence.

You vibe-code the business logic. I make sure your app is still standing two months from now — stable, secure, and with your data intact from day one.

You handle the business. I handle the tech.

You

Build the business logic

You know what your business needs — so you build exactly that. You shape the process, because nobody understands your business like you do.

Me

Keep the tech solid

I know what good code needs to look like. I keep it clean and handle the servers and the rest of the technical side — so nothing breaks the day real users show up.

Building something just for yourself? You probably don't need me. But the second other people start relying on it, data integrity, uptime, and security suddenly matter a lot. Let me help you get it right from the start — way cheaper than cleaning up a mess later.

I'm Krister Viirsaar — a friend to vibe coders.

A lot of developers are nervous right now — AI is taking over parts of their work. Honestly? I love it. It means good ideas don't die behind a crazy invoice anymore.

Yes, I'm a developer too. But I also run businesses, so I get it. I've watched a single button cost €500 and a website cost thousands. It genuinely makes me happy when people can just build the simple stuff themselves.

In a way, AI took my old job — I used to take prototypes from zero to a hundred. But the new way is better: you understand the business, so you build it. I understand the tech, so I make sure it actually holds up.

Already built your thing and something's nagging you? Happy to jump in and take a look. I promise my first reaction won't be "rewrite the whole thing." But if it turns out to be my second reaction — promise me you'll at least hear me out. :)

Vibe freely — I'll keep it standing.

The honeymoon is real. So is the bill.

The popular starter stack — Vercel + Supabase and friends — is genuinely great for getting started. Idea to working app in a weekend. For a prototype or a tool you use yourself, perfect.

But nobody mentions the catch: the same speed that makes month one feel like magic makes month four feel like a brick wall.

The pattern I keep seeing

  • All the logic in one file. Fast to write, impossible to grow.
  • Logic in three places at once. Frontend, database, edge functions — good luck finding where anything actually happens.
  • The browser drives your data updates. It writes the first half, the user closes the tab, the second half never runs — now your data's stuck halfway with no undo. A real backend does it all-or-nothing.
  • Security holes shipped as features. XSS, leaked keys, missing checks — the AI writes them in without blinking.
  • Hard limits at the worst moment. No long-running jobs: no real AI agents, no big uploads. You find out the day a customer needs one.
  • Spaghetti that compounds. Every shortcut makes the next one harder to avoid.
Fast to start

…falls apart later

Perfect for testing an idea or building something for yourself.

Built to last

…serves you for years

The boring, proven setup programmers have used for decades — for apps that need to keep growing for months and years.

That's the point: vibe-coding piles up technical debt fast, and fixing it eventually costs more than building it did. Neither stack is wrong — the mistake is using the fast one for a job that needs the lasting one. If your app's going to keep growing, let's lay the foundation now, while it's cheap.

Let's talk partnership

Now I'm the technical partner for Gold Adam — their team vibe-codes their internal app, and I keep the tech reliable and the data safe.
