On behalf of DB Systel GmbH, we built a web-based solution for Deutsche Bahn’s corporate clients to renew and optimize their bahn.business program portals.
The free bahn.business program offers special business rates to DB’s corporate customers.
Previously, three separate portals handled these offers.
The goal was to replace them with a single, more efficient portal.
The new portal features advanced user management and greatly reduces booking effort for companies.
Features include centralized payment management, consolidation of booking locations, adding new employees, assigning roles and rights, and comprehensive ticket spending reports.

Limbach Gruppe SE

I enhanced an internal software solution tailored to the needs of labs within the Limbach Group SE.
This software serves as a central and decentralized platform for data management across multiple labs.
The key challenge was building a complex, scalable, generic solution to integrate and standardize diverse lab processes and sensitive data.
The web app was built with Angular and ASP.NET as core components.
The generic complexity required resource- and performance-optimized implementation.
Limbach Group SE is a key infrastructure provider in Germany.

Hybrid

Senior Frontend Developer, Fullstack

Hays AG

Developed a hybrid progressive web app (PWA) focused on offline PDF management.
This module built on an existing Angular solution from DB Systel GmbH.
The new module lets users read, write, and edit PDFs offline.
Encrypted storage is handled via caching over a web interface.
The PWA communicates with the backend via AWS and AWS Cognito.
Using Capacitor, it was integrated into Android as part of an internal DB Systel app.
Internal staff access it through Android Enterprise; external specialists use web-enabled devices.
A key feature is editing PDFs with external tablet accessories like Bluetooth pens, mice, keyboards, and touch gestures.

For the mechanical engineering sector, I built a machine configuration solution with web, desktop, and mobile apps.
I created a React.js web app to configure and store machine settings centrally.
I extended it into a desktop app using Electron.

A core feature was Bluetooth communication between phone and machines.
I also built a robust Node.js REST API backed by MongoDB to avoid data loss on brief Bluetooth drops.
