ERP Program Manager at Fiserv
The customer is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a standard template worldwide.
The program also includes the “RISE with SAP” migration and modernization program, which may involve migrating the landscapes of selected country installations to the SAP Private Cloud.
On the stakeholder side, the program reporting line extends to the company’s executive board and that of the implementation partner.
Fiserv Germany’s ERP landscape currently includes several non-standard SAP tools and applications that extend the functionality of the ECC environment and can often be integrated into downstream systems. As part of the transition to SAP S/4HANA, it is essential to assess the core functionality, integration points and future viability of these applications in order to determine their alignment with the target architecture.
The focus of the work is on providing expert advice and assessment to define the scope, strategy and roadmap for transitioning Fiserv Germany’s SAP ECC system to SAP S/4HANA.
The recommended best practices from SAP are followed and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.
This assessment forms the basis for a successful SAP S/4HANA transformation and ensures alignment with industry best practices, regulatory compliance and future scalability.
Migration Strategy Definition – assessment of available transition approaches based on business objectives, technical feasibility and SAP Best Practices.
Technical Readiness Assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points and infrastructure readiness for SAP S/4HANA.
Business Process Impact Analysis – reviewing the latest business process documentation to define the scope and effort required to implement the necessary functions in SAP S/4HANA and to identify opportunities for process optimization.
Roadmap for Non-SAP Systems and Applications – assessment of third-party and legacy applications regarding their integration with SAP S/4HANA and recommendation of consolidation, migration or replacement strategies.
Deployment & Implementation Planning – defining a phased approach for implementation, including project schedules, risk mitigation strategies and key milestones aligned with business priorities.
This transformation takes place in phases: the Discovery phase leads to the Explore phase, which is followed by the Design phase and finally implementation.

About the technology
What Delphi is
Delphi is an object-oriented programming language and integrated development environment from Embarcadero. It is widely used to create native Windows applications, desktop business software and high-performance utilities. Its Object Pascal foundation, visual component model and compiled native code support productive development with direct system access.
Applications and systems
Delphi appears in long-running business systems as well as new desktop and cross-platform products. Companies use it where reliable local execution, rich user interfaces and controlled access to hardware or databases matter.
- Windows desktop applications for finance, logistics and operations
- Point-of-sale, inventory and industrial control software
- Database-driven administration and reporting tools
- Native utilities, device integrations and system services
Ecosystem and tooling
The Delphi ecosystem includes the VCL framework for Windows interfaces and FireMonkey for cross-platform user experiences. Strong specialists work with FireDAC, RAD Studio, REST clients, web services and database engines such as InterBase, Firebird, Microsoft SQL Server and PostgreSQL. They also use source control, automated builds, testing tools and third-party component libraries.
When expertise matters
Companies often bring in freelance Delphi specialists when a critical application needs maintenance, modernization or a controlled migration. They may need to replace legacy components, improve database performance, expose existing functionality through APIs or connect a desktop system to newer services.
- Upgrading older Delphi code and project files
- Refactoring tightly coupled forms and business logic
- Integrating REST APIs, payment services or hardware
- Moving desktop workflows toward web or mobile interfaces
What strong specialists deliver
Good Delphi professionals understand both the language and the business process embedded in the application. They can read older Object Pascal code, trace database transactions, manage memory and exceptions, and improve usability without breaking established workflows. They document decisions and make changes safely in systems that may be difficult to replace.
Choosing the right professional
Look for evidence of work with the relevant Delphi or RAD Studio generation, VCL or FireMonkey, database stack and deployment environment. Ask how the specialist approaches legacy code, regression testing, source-control practices and release planning. A useful technical discussion should connect proposed changes to measurable reliability, maintainability and user needs.
Frequently asked questions
Everything clients usually want to know about Delphi, in one place.
Delphi is used for native Windows applications, desktop business systems, database tools, industrial software and utilities that interact with hardware or operating-system services. It is also used for selected cross-platform applications through FireMonkey and for modern integrations through REST APIs.
A strong Delphi specialist can deliver compact native applications with fast startup, direct system access and a mature visual component model. C# often fits Microsoft-centered enterprise environments, while Java is common for portable server applications; the right choice depends on the existing codebase, deployment model and available skills.
A capable Delphi professional often works with Object Pascal, VCL, FireMonkey, FireDAC, SQL and REST services. Experience with Windows deployment, source control, automated testing, InterBase, Firebird or other relational databases is also valuable.
The needed level depends on the work rather than a fixed career duration. A focused feature may suit a specialist familiar with the application domain, while legacy modernization, database redesign or migration planning calls for someone who has handled complex Delphi systems and can assess hidden dependencies.
Yes. Delphi work can be managed remotely when the repository, build environment, test data and deployment process are accessible. Clear documentation, regular reviews and secure access to databases or hardware are especially important when the application depends on local infrastructure.
A Delphi application deserves modernization when maintenance is slow, dependencies are unsupported, testing is weak or users need integrations the current structure cannot support. Modernization can include refactoring, updated libraries, API integration, improved deployment or a gradual replacement of selected modules.
Ask the Delphi expert to explain a comparable system, the risks they found and how they tested changes. Strong answers cover code structure, database behavior, error handling, deployment and rollback, not only visual features or language syntax.
A Delphi freelancer should clarify the RAD Studio version, compiler targets, third-party components, database engines, source-control setup and release constraints. Understanding the business workflow is equally important because many Delphi systems combine user-interface logic, database rules and operational knowledge in one application.
The average hourly rate of freelancers who have used Delphi in their recent projects is 95 €, which corresponds to a daily rate of about 762 € based on an 8-hour working day.
