Performance and technical quality

Software and websites engineered for speed

Speed is not merely a visual detail: it affects user experience, productivity, application reliability and the ability to turn a visit into an enquiry or a sale.

For this reason, we develop optimized code, reduce unnecessary resources, correctly configure servers, caching and CDNs, and test performance on both desktop and mobile devices.

Optimized code

Lean applications, efficient queries and controlled resource loading.

Servers, caching and CDN

Infrastructure is configured together with the software, not treated as a separate concern.

Core Web Vitals

We monitor loading speed, responsiveness and visual stability through LCP, INP and CLS.

Mobile and desktop testing

Performance is assessed under different usage conditions, not only on powerful desktop computers.

Google Core Web Vitals

The essential metrics

LCP ≤ 1,5 s
Loading speed of the main content.
INP ≤ 200 ms
How quickly the page responds to interactions.
CLS ≤ 0,1
Visual stability of elements while loading.

Results may vary depending on the device, connection, external services and real-world user data. The objective is to achieve strong performance and, above all, a fast and stable experience under actual usage conditions.

Managed infrastructure

Dedicated servers and VPS selected for each project

We do not offer the same infrastructure to every client. We evaluate performance, data location, reliability, costs, scalability and technical requirements to select the most suitable solution for each project.

We can manage existing infrastructure or design new cloud environments, VPS and dedicated servers, while providing a single point of contact for configuration, security, monitoring, backups and support.

Independent assessment

The choice is based on technical requirements, not commercial partnerships.

European data centres

When required, we prioritise infrastructure and locations compatible with GDPR requirements.

Complete management

Installation, hardening, updates, monitoring, backups and support.

No technology lock-in

The infrastructure can be migrated or expanded as requirements and workloads change.

What we manage

Complete infrastructure, not just a server

VPS Dedicated servers Linux Cloud DNS Mail Firewall Backup Monitoring Cloudflare Nextcloud Migrations

We use different European and international operators depending on project requirements. RGStack is not tied to a single provider and retains technical responsibility for the proposed solution.
