Discovery call
We walk through the existing workflow, constraints, users, and the outcome you need. For agents, we also identify which decisions must remain human.
The method
Clear scope. Working previews. Your sign-off before launch.
You see what is being built and how it is checked. A written specification connects the business need to the tests, the sprint plan, and the final acceptance.
From discovery to maintenance
- 1
Discover
Walk through the workflow and define a useful first scope.
- 2
Specify
Write requirements, approval rules, and a sprint plan.
- 3
Build & verify
Test-first sprints, code review, and continuous integration.
- 4
Accept & launch
You test the preview and sign off before production.
- 5
Maintain
Monitor, fix problems, and plan the next improvements.
Written specification and sprint plan
We agree on scope, business rules, acceptance criteria, access, and a sequence of useful increments. The commercial proposal sets out the fixed setup or build fee and monthly maintenance.
Sprints with engineering checks
Test-first development makes important behavior explicit. Our lead engineer reviews the code, and continuous integration runs the automated checks and build. You can review progress in a preview environment.
Client acceptance testing
You test the agreed workflows in a preview environment using representative scenarios. Nothing ships to production without your sign-off. Open issues are resolved or explicitly agreed before release.
Launch
We check production configuration, access, and operating procedures, then release the accepted version. Agent triggers and permissions are enabled only within the approved scope.
Maintenance
The monthly arrangement covers monitoring and maintenance. Fixes keep the accepted system working; new features or expanded agent responsibilities get a written scope of their own.
Vibe coding with engineering guardrails
Vibe coding is building software by letting AI coding agents write the code from plain-language instructions. We use it every day, with a human engineer owning the specification, the review and the decision to ship.
1. Specification
Acceptance criteria approved before any code.
2. Failing test first
A test that reproduces the bug or describes the feature, seen failing before the code.
3. Fresh test database
Rebuilt from the branch’s migrations on every run, never the live database.
4. Code review
Every change is reviewed before its pull request is opened.
5. Blocking security review
A security finding stops the pull request.
6. Simplification
Duplication and dead code removed without changing behavior.
7. Full CI before merge
Lint, types, unit and integration tests, dependency audit, build and browser tests. Cancelled counts as red.
8. Production check and rollback
The deployed version and key pages are checked after each merge; if production breaks, the change is reverted first.
Remote collaboration, without guesswork
A shared written record
Requirements, decisions, and review notes stay in shared project tools. Asynchronous updates let you see progress without needing to attend every working session.
Time for direct conversation
We work from France, with overlap during US East Coast mornings. We agree on meeting windows and the channel for questions before the project starts.
Let’s start with the process you want to improve.
Bring the spreadsheet, the workflow, or the idea. We’ll talk through what is worth building and where human approval belongs.
