For founders with something real

The senior engineer who becomes your whole product team. And stays.

You built something real, maybe with AI. I build the rest, get it live and secure, and keep shipping it as you grow. Five years from now I am still the person who knows your whole system. No hiring, no rebuild, no cofounder equity, and you keep your code.

A founder-built app doesn't need a rewrite, and it doesn't need a cofounder who takes a third of your company. It needs a senior engineer who builds the rest, gets it safely live, and is still there when it grows. The founders I work with don't leave. My longest client stayed fifteen years.

The work, plainly

What “finish and launch” actually covers.

No mystery scope. This is the work that sits between the app you have and a business that runs on its own. You will probably recognize your own punch list in it.

01Finish the half-built features

The screens that almost work. The flow that dies on step three. I go through what the AI left dangling and close it out until the app does what you told people it does.

02Wire real payments

Stripe in live mode, not test mode. Webhooks that fire, receipts that send, failed cards that retry. Money lands in your account and you can see every charge.

03Lock down the security

Sign-in that can't be walked around. A database strangers can't read. The gaps that leak customer data get closed before customers arrive, not after.

04Give you an admin

Refund a customer, look up an account, change a price, ban a bad actor. You do it yourself, from one screen, without texting a developer.

05Get it launched

Your domain, working email, error alerts, backups. The unglamorous plumbing that separates a demo link from a product people trust with a card number.

06Keep it standing

Launch is a day. Running is the job. Monitoring watches around the clock, I fix what breaks, and when you want to grow there's a senior engineer who already knows your codebase.

Why me

A senior engineer's judgment, at agent speed.

My longest client's product ran on my code for fifteen years, until they grew big enough to bring the work in-house. That is how I work after launch: I stay on until you outgrow me. AI does the volume. I make every call that touches your users, your data, or your money.

“You built an app with AI. I finish it, launch it, and keep it running, so it will not break or fall over when real users show up.”

On the record

Shipped things you can go check.

No logo wall and no invented numbers. This is work that exists in public, with links.

The checklist founders actually use
I posted a pre-launch checklist for AI-built apps in r/nocode. Google ranks it first for “vibe coded app launch checklist.” This corner of the industry is where I live.

The partnershipContinuum

The main thing I offer is not leaving.

Launch is a day. Running and growing is the job. On Continuum I keep shipping your roadmap and keep the platform standing, from light monitoring all the way to a technical cofounder. Same senior hands, month to month, never locked in. Most founders start with one of the projects below and stay here for years.

Or start smaller

Start where you are.

Most people are not ready for a partnership on day one, and that is fine. Start with the piece you need today. Same senior hands, and the door to Continuum stays open.

The math you're actually doing

A technical cofounder costs 20 to 50 percent of your company. Getting finished and launched costs a fixed fee, once.

Keep your cap table. Get launched.

Start with a free check

Not sure where you stand? The free Leak Check ranks it for you.

Before you finish and launch, it helps to know what is actually exposed. The free Leak Check scans your live app and sorts what it finds into three buckets, so you know exactly where the next hour goes.

Where you end up

A few months from now, this is just your company.

The app is live at your own domain. People you have never met sign up, pay, and come back the next day. Something breaks on a Saturday and you hear about it after it is already fixed. Nobody took a third of your company to get you here. The thing you nearly gave up on, or nearly gave away, is out in the world earning.

That is the whole trade: a fixed fee and some of my attention, and you come out the other side a founder with a live product, not a person with a stalled build.

You built it. Let's get it shipped, safely.
