Engineered a high-performance web platform for a German security technology provider

MeinAlarm24 is a leading German provider of professional alarm systems and video surveillance for residential and commercial customers. Their goal is to make professional security accessible, transparent, and easy to configure for everyday users and business owners.

As the business scaled, their digital presence and internal operations needed to match the quality of their security systems — with faster lead capture, automated workflows, and reliable CRM integration across Salesforce, 3CX, and SharePoint.

• Traditional contact forms caused high drop-off rates — users wanted instant cost estimates before engaging
• Lead data flowed across Salesforce, 3CX, and SharePoint with no unified automation layer
• Generating tailored emergency call plans and contracts per customer was a manual, time-consuming process
• 3CX call summaries were at risk of being lost during high-concurrency periods with no queuing mechanism
• The site needed localised landing pages for city-level targeting without duplicating codebases

1. Replaced passive forms with an interactive price calculator

The Preisrechner (Price Calculator) was designed as a multi-step wizard giving users an instant cost estimate based on their property details — converting browsing intent into qualified lead capture at the moment of highest engagement.

2. Broke down data silos with a unified automation layer

Rather than leaving Salesforce, 3CX, and SharePoint as disconnected systems, we built a backend integration layer connecting all three — so leads, call summaries, and documents flow automatically without manual intervention.

3. Built for fault tolerance, not just performance

The 3CX webhook queuing mechanism using Azure Storage Queues was designed specifically to prevent data loss during peak periods — ensuring every call summary and lead is captured regardless of concurrency load.

4. Designed for localisation at scale

A dynamic routing architecture for city-level landing pages allowed MeinAlarm24 to target users in Hamburg, Berlin, and other regions without duplicating or maintaining separate codebases for each location.
