Web applications

Web that survives production

Platforms that operate: e-commerce, portals, event platforms and owned SaaS. Performance, accessibility and security by default.

In short

A production web app is measured on three things: speed on mobile, stability under load and traceability of what happens. We build platforms to that standard, from e-commerce to internal systems.

Evidence: the Paperless platform at JCDecaux Mexico, the payments work with Chanel EMEA and the official app of Colombia Tech Week 2026.

What we deliver

What platforms we build

We pick the stack by the case, not the fashion; the decision is documented.

01

E-commerce & payments

Catalogue, checkout, local payment methods (Klarna, Adyen) and reconciliation.

02

Internal platforms

SSO, approvals, dashboards and audit (see Paperless).

03

Event platforms

Agenda, networking, chat and maps that survive event-scale peaks.

04

Owned SaaS

Full-stack product with multi-tenancy, roles and billing.

New payment methods in days, not years

With Chanel EMEA we opened the path to integrate local payment methods (such as Klarna) on Chanel.com without depending on the worldwide roadmap: an autonomy diagnosis, Hybris and Adyen analysis, and a secure proxy architecture on a shared Adyen merchant account.
