Case studies

Synaps

Consulting and security

Implementing and validating ISO 27001 across front-end projects

We supported Synaps in implementing and validating the ISO 27001 standard on its front-end projects. Our engagement focused on applying security standards across every front-end project.

This involved reviewing development processes, putting security best practices in place (dependency management, protection against XSS attacks, etc.) and training the development teams.

GUIGUI Tech's application security expertise was a key factor in obtaining our ISO 27001 certification. Their pragmatic approach was much appreciated.

Genius Station

App development

Rebuilding a mobile trading app and integrating broker APIs

We fully rebuilt Genius Station's mobile app with React Native for native performance. One of the main goals was to reliably integrate the APIs of several trading brokers, including Binance and Alpaca.

We put particular effort into the real-time display of trading data, such as strategies, charts and candlesticks, to deliver a smooth and responsive user experience.

GUIGUI Tech transformed our app. The API integration and real-time display are flawless, which is crucial in trading.

Sagemcom

App development

Building a returnable equipment management app with a back office

For Sagemcom, we designed and developed a business application to manage returnable equipment. The solution traces each piece of equipment and manages its life cycle.

A complete admin back office was built so Sagemcom's teams can manage inventory, track equipment movements and generate detailed reports.

GUIGUI Tech fully understood our business needs and built a tailor-made solution that greatly simplified our logistics processes.

Galadrim

App development

Building an Expo app with a backend and an admin panel

As a subcontractor for Galadrim, we handled the full development of a mobile app built with Expo. The project included a Node.js backend and an admin panel.

The key feature was a custom forms system, used to build multi-step forms from the admin panel and render them dynamically in the mobile app.

The GUIGUI Tech team was remarkably efficient. They delivered a robust, flexible solution that fully satisfied our client.

Boardigo

App development

Building a mobile app and an electronic signature system

We built a mobile app for Boardigo with React and Capacitor, enabling fast deployment to iOS and Android. The backend was built with Node.js and deployed on a Kubernetes cluster for optimal scalability.

One of the main challenges was building an electronic signature system fully compliant with the European eIDAS regulation, ensuring the legal validity of signatures.

GUIGUI Tech took on complex technical challenges with real expertise. Their electronic signature solution is a genuine asset for our product.
