Process

How we work

A predictable method, with incremental deliveries and documented technical decisions at every step.

Discovery

We understand the problem, the audience and the constraints before writing a single line of code.

Architecture & Design

We define the architecture, scope and design of the solution, with documented technical decisions.

Development

Incremental deliveries, reviewed and tested, with full visibility of progress every week.

Delivery & Evolution

Deploy, monitoring and continuous support — the product keeps evolving with real usage data.

Commerce & Delivery2026

Vapt Food — Delivery ERP and marketplace

Challenge: Local businesses depend on high-fee marketplaces or on WhatsApp orders — no channel of their own, no control over the operation and no access to their own customer data.

Solution: A multi-tenant platform where each store builds its catalog, takes orders through its own digital menu and follows everything in real time, with delivery fees calculated from the customer's location.

Approach

How we choose technology

We're polyglot by choice: the language, framework and infrastructure follow from the problem — from long-term maintenance cost, not from hype. The list below is a sample of what we reach for most, not a boundary.

FAQ

Frequently asked questions

How does a project start?

We start with a discovery call to understand the problem, the goals and the constraints. From there, we present scope, timeline and a proposal — no strings attached.

Do you only work with the technologies listed?

No. The list is a sample of what we use most. We're full-stack and polyglot by choice: we evaluate the language, framework and infrastructure based on the problem, the team and the product's lifecycle — not the other way around.

What kind of projects do you take on?

From MVPs to critical systems in production: SaaS platforms, ERPs, high-volume APIs and complex integrations. We adapt the team and process to the size and stage of each product.

Do you take over existing or legacy systems?

Yes. We audit, stabilize and evolve systems already in production — including legacy code that needs to scale, become maintainable or migrate architecture.

Do we own the code?

Yes. All the code is yours, versioned and documented. We work with no lock-in and full transparency about every technical decision.

Do you provide support after delivery?

Yes. We offer ongoing support, fixes and continuous product evolution as the business needs it.
