How much does building a web application cost?

It varies a lot with complexity: a simple integration and a full SaaS platform are very different projects. That's why we estimate after we define the scope and features together. Ask for a conversation and we'll give you a realistic range, in phases.

What technologies do you use for development?

We use a modern and robust stack, including React/Next.js for frontend and Node.js/Express with PostgreSQL databases or scalable backend platforms for maximum security.

Can you continue a project started by another team?

Yes, we first conduct a technical audit of the existing code to see if it's more efficient to continue or rebuild the architecture.

How secure are the applications you build?

We apply strict security protocols (data encryption, CSRF/XSS protection, secure authentication) to guarantee data safety.

Do you offer long-term support?

Absolutely. We offer maintenance packages covering security updates, backups and adding new functionality.

Who owns the source code at the end?

You. The source code is yours at the end, no lock-in: you receive it in full and can continue with any team.

Why it matters

Software that fits your business, not the other way around.

From SaaS platforms to web apps (PWA) and synchronised web + mobile + admin ecosystems, built from scratch, with no themes or limitations.

From scratch, no shortcuts: no themes that limit you.
Real performance: server-side optimised, efficient queries.
Scalable by architecture: built for growth, not for a demo.
Connected ecosystem: web, mobile, admin, synchronised.
In-house & transparent: access to the code, a dedicated team.
The source code is yours: you own the code at the end, no lock-in.

Analytics dashboard and usage metrics

API & core integrations

The heart of the system that powers both the web and the mobile app.

Includes:

Single source of truth for data
Stable and scalable API versioning
Responses optimised for real time

Enterprise backend systems

Complex software with large volumes of corporate data.

Includes:

Microservices architectures
Audit logs (security and traceability)
Integration with internal systems (SSO / LDAP)

Maintenance & security

Monitoring, patching and dependency updates after launch.

Includes:

Encrypted backups, tested periodically
Protection against attacks and vulnerabilities
Constant dependency updates

Quick Clean

From Wix to Next.js, without losing Google rankings

At launch, measured with Google PageSpeed Insights: performance 100 on desktop and 96 on mobile, with 100 for accessibility, best practices and SEO on both. CLS 0. Image footprint cut from 83 MB to about 7.4 MB, a clean architecture with around 22 indexable pages. SEO parity preserved: 1:1 URLs and metadata, 21 verified redirects, validated JSON-LD. Clean cutover: uninterrupted email, HTTPS, zero downtime, with rollback available. Post-migration traffic is in its first observation window (4 weeks against the GSC baseline), with a defined alert threshold; at publication it is too early for traffic figures, and the methodology is built precisely to protect them. The old Wix subscription is closed only after stabilisation is confirmed.
