• Modernization of a large-scale Java enterprise application*

The project is modernizing a complex enterprise application that has grown over many years. The existing Spring-based legacy system runs on Java 8, OSGi, and Eclipse RCP and is being gradually migrated to a modern, maintainable architecture with Java 25 and Quarkus.

Marcus works on analysis, architecture, refactoring, and implementation. One focus is on untangling historically grown structures and dependencies and on building a clean, sustainable Java and Quarkus technology stack.

Tools & technologies: Java 8, Java 25, Quarkus, Hibernate ORM with Panache, EclipseLink, OSGi, Eclipse RCP, Maven, JUnit, Mockito, REST, JSON, Git, Eclipse IDE, IntelliJ IDEA Ultimate, Jira, Confluence

• Consulting across two integrated areas: Commercial Strategy (pricing, sales steering, marketing strategy, market expansion, margin management) and Operational Efficiency (process automation, AI integration, workflow design, last-mile automation).
• Development of custom SaaS solutions, explicitly tailored to the specific requirements and processes of each company.
• Delivery of AI training and change management workshops for managing directors and specialist departments, including AI competence training with a certificate of attendance under Art. 4 of the EU AI Act.

• Planned and managed strategy and daily operations for cross-functional team with end-to-end testing and launch readiness responsibility, facilitating early product launches.
• Managed complex set of stakeholders including weekly alignments (60+ regular participants), communications, risk management and budget.
• Implemented AI solution that reduced documentation and testing automation time by 60%.
• Restructured team into agile processes and quarterly iterations, delivering 400+ high-quality features in 15 epics according to time and quality expectations.

Outcome: Implementation of an APS solution (Eyelit) across multiple international production sites, including definition of target planning processes, integration architecture (SAP – APS via middleware), and alignment of complex manufacturing requirements (e.g. autoclave planning, alternative routings). Establishment of governance structures, steering formats and decision frameworks to manage scope, cost and timeline across multiple stakeholders. Successful handover of project leadership to internal successor, ensuring continuity and sustained project delivery.

Role in Project: Project Lead / Program Manager

Main Tasks in Project:

• Led APS implementation across multiple plants (Germany, Canada, France, US) with focus on end-to-end planning & scheduling processes and system integration
• Acted as central interface between business stakeholders (plants, operations), IT (SAP/middleware) and vendor (Eyelit)
• Drove requirements engineering, including consolidation of plant-specific requirements and steering of sign-off process
• Managed vendor (Eyelit) performance, including scope clarification, effort discussions and commercial alignment
• Identified and challenged gaps between standard APS functionality and complex manufacturing requirements (e.g. autoclave planning, batch optimization, alternative routings)
• Defined and implemented project governance structures, including Steering Committees, risk reporting and decision frameworks
• Led escalation management on cost overruns, scope deviations and delivery transparency
• Coordinated integration strategy (decision for custom middleware vs. standard connector) and alignment with SAP landscape
• Improved project transparency and way of working, including definition of reporting structures, tracking logic and communication cadence
• Facilitated alignment between global and local stakeholders to ensure feasible timelines, resource planning and plant readiness
• Prepared and delivered SteerCo updates and executive decision documents
• Managed structured project handover to internal project lead, including knowledge transfer, documentation alignment and stakeholder transition.

• Designed role-based delivery assignment workflows, switchable between own fleet and partner carriers, with traceable status chains from „pending“ to „in delivery.“
• Designed AI-assisted route optimization, where dispatchers review drive-time-optimized route suggestions as drafts and apply them in one click.
• Designed a central planning interface for delivery and route management, bringing table view, map view, and route composition into a single workflow.
• Built interactive prototypes to align new product features early with stakeholders and engineering.
