"We've been two weeks from launch since March."

Custom SaaS development that ends in a product real users can pay for - not another demo. An idea, a Figma file or a stalled repo becomes a deployed Next.js app running on your infrastructure, under your accounts.

WHAT LANDS IN YOUR ACCOUNTS
Data model & typed API
Auth, roles & Stripe billing
Admin panel you can run
CI/CD, staging & prod

"It works, but next to our competitor it feels cheap."

You stop losing signups to a better-looking rival. Pixel-faithful Figma to React components, plus the motion layer that makes software feel expensive - fast on a mid-range Android, not just your laptop.

WHAT LANDS IN YOUR ACCOUNTS
Figma → React, pixel-faithful
Documented component library
360px → ultrawide
60fps motion budget

"Two people spend every morning copy-pasting between tools."

You get those mornings back. Workflow automation built around an LLM pipeline that logs every decision, asks a human when it isn't sure, and pages you when it fails instead of failing quietly.

WHAT LANDS IN YOUR ACCOUNTS
LLM workflows on your data
Document & support triage
Meta Graph + Stripe pipelines
Idempotent webhooks, retries
Human approval steps

"The only person who understood the codebase left in April."

You get your own codebase back in writing: what is solid, what is rotting, what it costs to fix. A week of forensic reading, then a costed roadmap any developer - me or yours - can execute.

BEFORE YOU ASK
We already have a half-built app. Do you start over?

Almost never. I read the repo before quoting and tell you what is worth keeping, what needs rewriting and what each costs - in writing, before anyone touches main.

Isn't one freelance developer a risk for a build this size?

Everything lands in your repo, your cloud and your Stripe from day one, documented as it ships. If I vanish, the next developer reads the handover doc and keeps going.

What if the scope changes halfway through?

It usually does. New work is priced as a short written addendum before I build it, so the final invoice is a number you already approved.

How much of our time does this take?

One 30-minute call a week and quick answers when I'm blocked. Every Friday you get a deployed preview link instead of a status email.

Our designer left - can you work from what we have?

Yes. Figma, a Sketch export, or just the live site and screenshots. Where the source is missing states, I design them and get them approved before building.

Will it still feel fast on a cheap Android phone?

That's the device I test on, not my laptop. Motion runs inside a 60fps budget and Core Web Vitals are measured throttled before handover.

Do we get components, or just the pages?

A documented component library in your repo - named, typed, every state built - so your team ships the next ten screens without me.

Can you match our brand without a design system?

I derive one as I go: type scale, spacing, colour roles and motion rules, written into the repo so the next screen doesn't drift.

Where does our data actually go?

Into your accounts, through API keys you own, with training opt-out on by default. Every place data leaves your infrastructure is written down before it runs in production.

What happens when the model gets it wrong?

Anything touching money or a customer stops for a human. Every run is logged with its inputs and output, so a bad answer is replayable instead of a mystery.

Will it break when a tool changes its API?

Integrations are versioned, idempotent and retried, and they page you when a provider changes shape. Loud failure beats work silently skipped.

How is this priced, and what does it cost to run?

A fixed fee for the build, no hourly rate and no retainer. Each workflow then gets a cost ceiling per run and a dashboard of spend against work done, so the saving is a number you can check rather than a promise.

Can you read a codebase cold, with nobody left to ask?

That's the job. I work from the repo, the deploy config and the database; what the code can't answer goes in the report as a risk, not a guess.

Do you rewrite it, or just tell us it's bad?

Neither alone. Every area gets a keep / refactor / rewrite call with a cost and a reason, so you can argue with the reasoning instead of a vibe.

Can our own developers execute the roadmap?

It's written for them: ordered, costed, risky items flagged. Hiring me for the fixes is an option, not the point of the document.

How fast do we know if it's salvageable?

Three to five days for the full read. If it is structurally doomed you hear that on day two, not at the end of the week.

Six years in.

A freelance full-stack developer working solo, end to end. How the work actually gets made - and what you can hold me to.

METHOD
Writes the migration before the feature.
TASTE
Prefers boring technology that outlives the hype.

ACCOUNTABILITY
Carries the pager for what he builds.

The job stopped being about code. I build the whole SaaS - interface to database to deploy - and I stay until it survives real users.
