Let’s simplify your workflowWAYS TO START
A specific problem.
A working deliverable.
Choose the job you need done. We review your starting point and agree on scope, price, and acceptance before work begins.
Fix your AI-built app.
For a React, Next.js, or Supabase app that looks ready but breaks when people use it.
- Reproduce and trace one critical failing user flow.
- Fix the underlying code or database issue.
- Run regression checks and hand over a verified release.
Bring: your repository, a failing example, and access to a test environment.
Scope an app fixAutomate one recurring task.
For manual intake, lead follow-up, document handling, or repeated work between business tools.
- Map one trigger-to-result workflow and connect the agreed tools.
- Add AI where useful, with validation and human review.
- Test normal and failure paths; document how to run it.
Bring: a walkthrough of the task, sample inputs, and the tools involved.
Scope an automationMake your AI tools useful.
For a project that needs a reliable coding-agent setup or a cleaner existing environment.
- Configure one repository with project instructions and reusable skills.
- Connect one agreed MCP or API integration and verify permissions.
- Run a real task together and hand over setup documentation.
Bring: your repository, current setup, and a task you want the agent to handle.
Scope an AI setupBuild the first useful version.
For a SaaS product, client portal, or internal tool with a clear first user journey.
- Define the core flow, screens, data model, and permissions.
- Build the frontend, backend, and agreed integrations.
- Test the core journey, deploy, and hand over source and documentation.
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
AI in the build.

Before we start.
Can you work on our existing code?
Yes. Share the stack, repository, and the issue or feature you want to address. We review the current system before recommending changes.
How do you price the work?
We agree on a defined milestone, deliverables, price, and acceptance criteria after reviewing your brief. Further work gets its own scope. Hosting, API usage, and paid services are agreed separately.
What do we get at handover?
The project source, setup and deployment notes, and a walkthrough of the agreed deliverables. We confirm account ownership, access, and any third-party dependencies before work begins.
Do you only use Claude Code and Codex?
They support our development process. Your project determines the application stack and integrations; we review the code and verify the agreed user flows before handover.
