Let’s simplify your workflowWAYS TO START
Choose the job you need done. We review your starting point and agree on scope, price, and acceptance before work begins.
For a React, Next.js, or Supabase app that looks ready but breaks when people use it.
Bring: your repository, a failing example, and access to a test environment.
Scope an app fixFor manual intake, lead follow-up, document handling, or repeated work between business tools.
Bring: a walkthrough of the task, sample inputs, and the tools involved.
Scope an automationFor a project that needs a reliable coding-agent setup or a cleaner existing environment.
Bring: your repository, current setup, and a task you want the agent to handle.
Scope an AI setupFor a SaaS product, client portal, or internal tool with a clear first user journey.
Bring: your target user, core use case, and any existing designs or code.
Scope an MVPStart with a defined milestone. Larger builds follow an agreed plan; hosting, API usage, and paid tools are costed separately.
THE TOOLS BEHIND THE WORK
We use Claude Code and Codex throughout development. We define the architecture, review the output, test the important paths, and take responsibility for the handover.
How we bring it together
Development, debugging, and iteration
Reusable instructions shaped around your work

HOW WE WORK
You know what we’re building, why it matters, and what comes next.

Walk us through the product or process. We agree on the scope, priorities, and what a useful result looks like.
Review working increments, give feedback, and see the product take shape before the final handover.
We test, deploy, and walk you through the system. You get the source code and documentation to carry it forward.
