Rescue & Hardening
Your AI-built app made safe to launch: access control, payments, deploys and monitoring.
$1,800 from — range $1,800–$2,500
Services
Two we sell at a price. Three we quote.
Rescue and store launch are productized — fixed scope, published price, stated turnaround — because they are the same work almost every time. Web, app and AI agent builds are quoted after a scoping call, because a new build has no typical size.
01Productized
Fixed price, published
The same work almost every time, so it is sold like a product: a fixed scope agreed from an audit, a number you can read before you talk to us, and a stated turnaround.
Mobile & Store Launch
Your app packaged, compliant and submitted — through review, not just uploaded.
$2,500 from — range $2,500–$4,000
02Quoted
Quoted after a scoping call
A new build has no typical size, so a published price would only mean padding it to cover the worst case. Everything here ships with the same foundations the rescue work puts back.
Web development
New applications and new features, built production-ready from the first commit.
App development
Mobile apps built to ship — iOS and Android, through review and into the stores.
AI agent development
LLM features that behave in production — tools, evals, cost control and MCP servers.
03Method
How every engagement runs
Read-only first
We begin with viewer access. Write access is requested when a sprint starts and revoked when it ends.
Fixed scope, fixed price
Scope is agreed in writing before work begins. Work outside it is a separate quote, never an adjusted invoice.
Your repository
Branches and pull requests you review. Nothing of ours is left behind that you would need us to maintain.
Written handover
Every change described in plain language, so the next engineer — or you — can pick it up without us.
04Stack
What we work in
Split into what we default to and what we also work in. If your system is outside this, tell us on the call — we would rather say no than learn a stack on your budget.
Web
Frontend and full-stack
TypeScript everywhere, and a framework that renders on the server unless the product is purely an application behind a login.
We default to
- TypeScript
- React
- Next.js
- Astro
- Tailwind CSS
- Vite
We also work in
- JavaScript
- Remix
- SvelteKit
- Vue 3
- Nuxt
- shadcn/ui
- Radix UI
- TanStack Query
- TanStack Table

- Zustand
- Redux Toolkit
- Framer Motion
- MDX
- Storybook
- Vitest
- Playwright
- Testing Library
- ESLint
- Prettier
- Recharts
- D3
API
Backend and services
Boring, typed and synchronous until something measurably needs to be a queue. Most systems need fewer moving parts than they are given.
We default to
- Node.js
- Python
- REST
- tRPC
- Background jobs
- Queues
We also work in
- Hono

- Express

- Stripe
- Paddle
- Razorpay
- Resend
- Postmark
- Twilio
- Webhooks in both directions
Data
Databases and storage
Postgres unless there is a specific reason otherwise, migrations in the repository, and a restore that has been executed rather than merely configured.
We default to

- Meilisearch
- Typesense
- Elasticsearch
- S3

App
Mobile
Expo unless the product is the platform experience. One codebase is worth a great deal when the maintenance bill outlasts the project.
We default to

- Capacitor
- Flutter
- SwiftUI
- Jetpack Compose

- Google Play Console
- Detox
- Maestro
- Privacy manifests
Ops
Infrastructure and observability
Managed platforms until scale or cost argues otherwise. The parts we insist on are a deploy you can roll back and an error that reaches a human.

We also work in
- AWS
- Cloudflare Workers
- Cloudflare R2
- Cloudflare D1

- Axiom
- Better Stack
- Checkly
- Uptime checks

AI
AI systems
Hosted models behind an interface you can swap, with the eval set deciding which one you use this quarter rather than a contract.
We default to
- Claude

We also work in
- Gemini
- OpenRouter
- LiteLLM

- LangSmith
- Braintrust
- Helicone
- Ollama
- vLLM
- OAuth 2.1 for MCP
Every engagement starts with the audit.
It is the only way we will quote a sprint, because it is the only way either of us knows what the work actually is. Fixed price, two business days, and credited in full if you go ahead.
