# Web application development | Slash Digital Lab, Bogotá Source: https://slash-digital.io/en/web-applications/ Digital product & software Platforms that operate: e-commerce, portals, event platforms and owned SaaS. Performance, accessibility and security by default. - Performance Core Web Vitals - Accessibility WCAG 2.2 AA - Cases Chanel · Paperless Start a project See real work In short Slash Digital Lab builds production web applications from Bogotá, and a 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, the B2B and B2C wine e-commerce of UVAS Trading in Madrid and the official app of Colombia Tech Week 2026. When the web is part of a full product, we run it as a digital product, with a mobile app when needed. What we deliver ## What platforms we build We pick the stack case by case and write the decision down. 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. How we work ## How we ship production web - ### Architecture Stack, performance and security decisions documented before coding. - ### Build Sprints with demos; per-page performance budgets. - ### Testing Accessibility, load and edge cases on low-end phones. - ### Launch Deployment, monitoring and an incident-response plan. Scope and deliverables ## What the project delivers - **Performance:** Per-page budgets and Core Web Vitals targets. - **Security:** OWASP, headers, dependency reviews. - **Accessibility:** WCAG 2.2 AA verified. - **CMS:** Frictionless self-service content management. - **Integrations:** Payments, CRM, ERP and own APIs. - **Observability:** Logs, metrics and alerts from day one.

Learn more → Frequently asked questions ## The questions we hear often **Modernize legacy or start fresh?** Both; discovery shows where rebuilding pays and where modernization is enough. **Headless or SAP Commerce?** Yes; the proxy architecture we designed with Chanel EMEA is an example. **Can our team edit content?** Yes: a CMS for content changes without developer dependency. **How long is a portal?** Discovery to production typically runs 8–16 weeks by scope. **What about post-launch growth?** Yes: two months of support included after delivery; then a version plan, monitoring and a priority-driven backlog on the support plan you choose. **What technology do you build with?** Mostly with Next.js, Node.js and Python; the case decides, and the decision is documented before coding. What doesn't change is the standard: per-page performance budgets with Core Web Vitals targets, verified WCAG 2.2 AA accessibility and OWASP security with dependency reviews. We integrate payments such as Klarna or Adyen, CRM, ERP and your own APIs. **How do you protect the platform and user data?** With security by default: OWASP, headers and dependency reviews; SSO, approvals and audit on internal platforms; logs, metrics and alerts from day one, and an incident-response plan at launch. When you need it, our own pentest practice tests the platform. **Where do you host the application and the data?** Mainly on Supabase (database, authentication and storage), OVHcloud and Microsoft Azure. We pick the provider and region based on the data residency your case requires and what your company already uses, and we handle personal data under Colombia's Law 1581 of 2012 and the GDPR in Europe.
