I take ownership of a complete product flow: interface, data, API and operations. This fits when you need one technical owner to close the delivery and leave code your team can continue.

-   Frontend and backend with shared acceptance criteria.
-   A scoped flow before estimating the project.
-   Code, configuration and pending work documented.

## Arafilum: interface, sales and operations

Full-stack store MVP for a direct client who permits publication.

[Review the case and delivered scope](/en/cases/arafilum-operational-ecommerce)

Catalog and checkout on the public store.

Connected payments, orders, invoices, emails and shipping.

Administration to manage operations.

## From a business flow to a verifiable delivery

Scope connects what the user sees with what the team needs to operate.

01

### Interface and states

Screens, forms, validation and loading or error states needed to complete the flow.

02

### Backend and integration

Data model, permissions and API contracts, including what happens when an external service fails.

03

### Delivery and continuity

Flow checks, agreed deployment and documentation of configuration, limitations and next changes.

## Common Questions

The minimum worth clarifying before opening a collaboration.

Can this be white-label?+

Yes. I can stay behind the agency, work under NDA and keep the client relationship protected.

Can you work on an existing codebase?+

Yes. I review the base, clarify constraints and enter the specific piece without forcing a rewrite.

What do you need to start?+

Objective, timing, current state, access if needed and the main technical blocker.

What changes the project estimate?+

Required user journeys, roles and permissions, availability of design and content and integration complexity. An enquiry website with one form and a store with payments, orders and administration have different scopes. The proposal defines deliverables, dependencies and acceptance criteria before price and timing are fixed.

## Keep Comparing

If you are still comparing options, these routes help narrow the decision.

## If it fits, start with context.

With objective, timing, current state and the technical blocker, I can reply with the next step.
