Commercial vehicles ? financial planning and reporting platform, Vaadin 8 to 25 in production (~100,000 LoC)

Software engineer, migration specialist Java Vaadin Spring Boot ...
Software engineer, migration specialist
Project context: an international financial planning and reporting platform of ~100,000 LoC - forecasting cash flows, signing off pre-orders, reporting on past periods side by side - sat on a Vaadin version approaching end of support, and could not be taken offline for a rewrite.
My tasks: carry the platform from Vaadin 8 to 25 while it stayed live in production. Add single sign-on (Entra ID, Keycloak) and real-time collaborative editing for globally distributed teams. Break an ~8,000-line god class behind the reporting view into reusable parts.
Result: the tool the company plans and approves its money with runs on a current, supported and secure platform, without a delivery freeze; new report types are now assembled from reusable parts.
Across the five years the engagement also covered ongoing maintenance and feature additions.

Senior consultant, migration specialist, mentor
Project context: various projects in an enterprise web application context, for end customers in automotive, medical devices, finance, banking, public administration and pharma: large business applications with a long service life, most of them on stacks that had outlived their support.
My tasks: migrate business-critical applications while they stay live in production, carry regulated software through the same path, and mentor customer development teams.
Result: I keep business-critical applications on a current, supported platform without a delivery freeze.

Energy ? ESP32 firmware and touch HMI for photovoltaic surplus control

Developer, firmware and HMI C embedded firmware ...
Developer, firmware and HMI
Project context: photovoltaic surplus was being fed to the grid instead of consumed in the building.
My tasks: firmware and touch-panel HMI on an ESP32 panel: poll a 3-phase energy meter, display live power flow, and switch up to four loads by a priority-based surplus algorithm, each with master enable, manual/auto override and a configurable threshold in watts; persist all twelve settings.
Result: I delivered finished, working one-off units.

Software engineer, took the system over
Project context: an orphaned under-vehicle inspection system. The original developer had left with a divergent copy; client and server had drifted apart, and shipping was on hold.
My tasks: reconstruct a working system from the broken code, rework direct component wiring into real-time TCP/IP, integrate a Phoenix PLC and its human-machine interface, and commission units on site, including at a high-security site.
Result: I made the product shippable again and deliveries of new units resumed. A year later this customer hardware became the live demo of my GOTO 2015 Berlin talk: a real traffic-light installation in the conference hall, driven from a phone.

Customer project lead and developer
Project context: the vendor mixed-criticality claim - Android on a virtualized head unit running alongside hard-real-time processing on the same NXP iMX hardware - had to be proven to automotive customers on real silicon, not on a simulator.
My tasks: run the customer projects, workshops, performance and test scenarios, scoping and estimation, and build the AUTOSAR park-distance control that carried the proof, on an L4 microkernel hypervisor with Android and a real-time guest side by side.
Result: the concept held up on real hardware and went on show as the company demonstrator.

Position

Position

Fünf Felder, und die meisten Mandate berühren mehr als eines.

Vaadin und Enterprise-Web: Ich hole Anwendungen, die im Betrieb bleiben müssen, von Vaadin Framework 6/7/8, Swing, SWT oder Struts auf Vaadin Flow 25 ? schrittweise, ohne Auslieferungsstopp. Dahinter Spring Boot mit Spring Data und Spring Security, REST, und Hilla, wo eine JavaScript-Oberfläche gewollt ist. Gerufen werde ich für das, was solche Vorhaben aufhält: Single Sign-on, Echtzeit-Zusammenarbeit, Threading, Barrierefreiheit.

Embedded und hardwarenah: Firmware und Treiber in C/C++ auf ARM und ESP32, bare metal, FreeRTOS oder Embedded Linux; Echtzeitsteuerung über CAN/LIN, RS485 und Modbus; SPS samt Bedienoberfläche; Inbetriebnahme vor Ort. Zertifizierbare Arbeit nach EN 62304 (Medizin) und BSI TR-03109 (Kryptografie und PKI).

Mobile: iOS- und Android-Anwendungen, Prozess-Bedienoberflächen auf angepassten Tablets; meine eigene Verschlüsselungs-App steht seit 2011 im App Store.

Schneller liefern, geprüft: Ich schreibe die Spezifikation, die KI schreibt dagegen, und ich prüfe das Ergebnis gegen die Spezifikation ? wo es sich lohnt, auch formal.

Führung und Kommunikation: Projekte mit bis zu 15 Entwicklern, Mentoring, Schulungen, Konferenzvorträge ? deutsch und englisch.
