Luca Pacor
Last position:
ERP Program Manager at Fiserv
The client is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a global standard template.
The program also includes the migration and modernization initiative "RISE with SAP", which may involve migrating selected country installations to the SAP Private Cloud.
On the stakeholder side, the program's reporting line extends up to the company's board and the implementation partner's board.
Fiserv Germany's ERP landscape currently includes several non-standard SAP tools and applications that extend the ECC environment's functionality and often integrate with downstream systems. As part of the move to SAP S/4HANA, it is essential to assess the core functionality, integration points, and future viability of these applications to determine their alignment with the target architecture.
The focus of the role is to provide expert advice and assessment to define the scope, strategy, and roadmap for migrating Fiserv Germany's SAP ECC system to SAP S/4HANA.
SAP's recommended best practices 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, ensuring alignment with industry best practices, regulatory compliance, and future scalability.
Migration strategy definition – evaluating 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 needed to implement required functions in SAP S/4HANA and identify process optimization opportunities.
Roadmap for non-SAP systems and applications – evaluating third-party and legacy applications for SAP S/4HANA integration and recommending consolidation, migration, or replacement strategies.
Deployment & implementation planning – defining a phased rollout approach, including project timelines, risk mitigation strategies, and key milestones aligned with business priorities.
The transformation is carried out in phases: the discovery phase leads to the explore phase, which then leads to the design phase and finally to the implementation phase.

About the technology
Tcl in practice
Tcl, short for Tool Command Language, is a scripting language used for automation, control, and glue code. It is common where teams need reliable scripting around existing systems, hardware, test tools, or legacy applications. Tcl/Tk is still used for desktop interfaces in some environments.
Typical work
- Test automation and lab scripts
- Build and maintenance tooling
- Device, network, and system control
- Tcl/Tk user interfaces
- Integration scripts around C, shell, and Python
Ecosystem
Strong Tcl work often includes Tk for interfaces, Expect for interactive command automation, and extension work in C for performance or device access. Many projects also rely on careful package handling, reusable procedures, and clear conventions for namespacing. A good specialist knows how Tcl fits into older enterprise stacks as well as custom tooling.
When to bring in freelance help
Companies often look for freelance Tcl experts when a script chain is fragile, a test harness needs cleanup, or an internal tool must be maintained without rewriting the whole stack. In Germany, this comes up in industrial software, telecom, lab systems, and products with long-lived codebases. Freelancers are also useful when teams need short-term support for a release or migration.
What strong experts do
A strong Tcl professional writes readable scripts, understands stateful flows, and can debug shell, network, and process issues quickly. They know when to keep logic in Tcl and when to push work into extensions or surrounding tools. Good experts document handoffs well so the next specialist can continue cleanly.
Good project fit
If your project depends on scripts that must keep running, Tcl is often the right choice. It is a practical fit for automation around legacy systems, custom test environments, and controlled interfaces that are not easy to replace. The best results come from experts who understand both the language and the system around it.
Frequently asked questions
Not sure where to start with Tcl? These answers cover the essentials.
Tcl is used for automation, system control, test harnesses, and scriptable tooling around existing software or hardware. It is also used with Tcl/Tk for interfaces and with Expect for interactive command flows. Companies choose it when they need dependable scripting that fits into an older or tightly controlled environment.
Tcl is often chosen for embedded scripting and tool integration where the language sits close to the system it controls. Python is broader for application logic, while Bash is narrower and less comfortable for complex flow. Tcl can be a better fit when you need a small, consistent scripting layer inside another product or test setup.
A strong Tcl specialist usually knows Tk, Expect, shell scripting, and at least one systems language such as C for extensions or integration. Experience with testing tools, networked systems, and legacy maintenance is also valuable. The best people understand how Tcl scripts interact with processes, files, and command-line tools.
A Tcl project that only needs a few scripts may be handled by a generalist with solid scripting habits. A larger codebase, test framework, or production control system usually needs someone who has worked with Tcl before and can read older code quickly. The more stateful and critical the system, the more valuable deep Tcl experience becomes.
Yes, Tcl work is often well suited to remote collaboration because much of it is script review, debugging, and integration work. For lab systems, internal tools, or on-site hardware, a hybrid setup can help at the start. Teams in Germany often want clear written handover notes and communication in English, and sometimes German for local stakeholders.
Tcl and Tk are often mentioned together because Tk is the GUI toolkit commonly used with Tcl. It matters when a project still has a desktop interface, control panel, or internal tool that is easier to maintain than replace. If your interface is part of the script layer, a Tcl/Tk specialist is the right fit.
Look for clean script structure, consistent naming, and careful handling of errors and state in Tcl. Good experts can explain old code, improve it without breaking behavior, and show how they test changes. They should also know when a problem is really in the surrounding system, not in Tcl itself.
Use Tcl extensions like Expect when your scripts must talk to interactive command-line tools, devices, or systems that do not expose a clean API. Extensions are also useful when you need performance, protocol support, or access to existing libraries. A good specialist will choose the smallest extension that solves the problem cleanly.
The average hourly rate of freelancers in Germany who have used Tcl in their recent projects is 100 €, which corresponds to a daily rate of about 798 € based on an 8-hour working day.
Of the freelancers in Germany who have used Tcl in their recent projects, 100% hold at least a Bachelor's degree and 55% hold at least a Master's degree.
