Last position:
Power BI Developer & Consultant in an Agile Team (SAFe) at DB InfraGO AG
Further Development of the Integrated Capacity Management Platform InKa
Rail Infrastructure
- Power BI shared datasets and reports via DirectQuery on Amazon Redshift (timetable, construction and capacity data)
- Automated report testing with Playwright in Docker containers, version control with GitLab
- Concept and implementation of user communication (information page, changelog, known bugs)
Initial Situation:
The integrated capacity management platform (InKa) is a monitoring and analysis platform for data from timetable and capacity management: customer orders, infrastructure, timetable operations, construction, as well as route capacity and width. The data is stored and linked in a structured data warehouse. This makes it possible to create complex KPIs across different source systems and display current and future route utilization as well as construction activity across the network. The goal is to improve strategic, medium-term and intra-year planning and provide users with easy access to capacity management analyses.
Measures:
- Enablement: Introduction of Power BI with training and workshops for development teams.
- Consulting & Design: Problem analysis, concepts and solution consulting for reporting requirements; implementation of reporting solution plans.
- Data Model: Development of shared datasets with DirectQuery on Amazon Redshift and import tables; DAX measures for utilization and capacity KPIs.
- Development: Data analysis, data transformation and visualization in Power BI; extension and migration of business applications to Power BI; AI-supported development in VS Code with GitHub Copilot.
- Test Automation: Automated testing of Power BI reports with Playwright; setup of the test environment in Docker containers.
- User Communication: Concept and implementation of a central information page with hot news, changelog and known bugs, access from reports with report filters, updates via Power Automate.
- Deployment: Management of Power BI Deployment Pipelines across the DEV, TEST and PROD environments.
- Agile Working: Work in an agile team according to SAFe (Scaled Agile Framework); refinement of user stories and features including effort estimates in Jira; version control with Git and GitLab.
- Quality & Documentation: Reviews for quality assurance, error analysis and resolution, technical documentation in AsciiDoc and Confluence.
Technologies: Power BI, DAX, Power Query, DirectQuery, Amazon Redshift, Git / GitLab, Deployment Pipelines, Playwright, Docker, AsciiDoc, Power Automate, Jira, Confluence, VS Code with GitHub Copilot, SAFe
Results:
- Capacity management KPIs from multiple source systems combined on one platform
- Transparency regarding current and future route utilization and construction activity across the network
- Easy access to analyses for users
- Automated regression testing of Power BI reports
- User communication implemented: central information page with hot news, changelog and known bugs, directly accessible from the reports

About the technology
What C++ is
C++ is a compiled, general-purpose language used where performance, memory control and predictable execution matter. It supports object-oriented, generic and low-level programming in one codebase. The language is common in systems software, desktop products, games, trading infrastructure and embedded devices.
Where it runs
C++ powers software that must respond quickly or work close to hardware. Companies use it for operating systems, robotics, simulation, computer vision, audio processing and large-scale backend components. It also sits behind major game engines, browsers, databases and industrial control systems.
- Embedded firmware and device software
- Game engines and real-time graphics
- Robotics, vision and simulation systems
- High-throughput services and data pipelines
Ecosystem and tooling
Strong C++ work depends on more than syntax. Professionals work with the Standard Library, Boost, CMake, Conan or vcpkg, and testing frameworks such as GoogleTest. Depending on the product, they may also use Qt, Unreal Engine, CUDA, OpenGL, POSIX APIs or cross-compilation toolchains.
When companies need specialists
Freelance expertise helps when a product needs faster execution, a hardware integration or a safe modernization path. Companies also bring in specialists to resolve memory leaks, reduce build times, replace legacy C++ code, or create a stable release pipeline. Clear interfaces and maintainable tests are often as important as raw speed.
- Diagnose crashes, race conditions and performance bottlenecks
- Port software across operating systems or hardware targets
- Modernize older code with current C++ standards
- Set up builds, testing, profiling and continuous integration
What strong professionals bring
A capable C++ professional understands ownership, lifetimes, concurrency and resource management in detail. They use profiling and measurement instead of guessing, and they explain trade-offs between safety, speed and complexity. Experience with APIs, hardware constraints, version control and automated testing helps turn isolated code into dependable software.
Choosing the right fit
Start with the runtime environment, target hardware, operating systems and performance constraints. Ask for examples of comparable systems, the debugging tools used and how quality was verified. For remote work, document build steps, interfaces and test environments clearly; on-site collaboration can be valuable when hardware, lab equipment or factory systems are involved.
Frequently asked questions
Quick answers to the questions that come up most around C++.
C++ is used for operating systems, embedded devices, game engines, desktop applications and high-performance services. It is also common in robotics, computer vision, simulation, finance and software that communicates directly with hardware.
C++ offers fine-grained control and a mature ecosystem, but it requires careful management of memory, concurrency and compatibility. Rust provides stronger compile-time safety, C is simpler and closer to the machine, while Java trades some control for managed memory and portability. The right choice depends on hardware access, existing code and delivery constraints.
A strong C++ specialist often brings knowledge of CMake, Linux, Windows, Git, debugging and automated testing. Depending on the project, useful adjacent skills include Qt, CUDA, OpenGL, networking, embedded operating systems, SQL or cloud deployment.
The required depth depends on the risk and technical constraints, not only on the size of the codebase. C++ work involving concurrency, hardware, real-time behavior or legacy migrations needs a professional who can reason about lifetimes, undefined behavior and profiling from the start.
C++ projects can often be delivered remotely when source code, toolchains, hardware access and test data are available. On-site work may be useful for embedded products, laboratory equipment, factory systems or hardware debugging. Shared build instructions and reproducible tests make remote collaboration much easier.
Review whether the C++ code has clear ownership rules, focused interfaces, useful tests and predictable error handling. Ask how the professional investigates memory issues, race conditions and slow paths. Profiling results, maintainability and safe release practices matter more than clever syntax.
Modern C++ can improve safety, clarity and library usage without requiring a full rewrite. A specialist should identify high-risk areas, introduce changes incrementally and preserve behavior with tests. Rewriting everything is rarely the safest first step for a production system.
A useful C++ brief describes the target platforms, compiler versions, build system, hardware interfaces and performance goals. Include the current architecture, known defects, test coverage and release process. This lets a professional estimate the work and identify technical risks before implementation begins.
The average hourly rate of freelancers who have used C++ in their recent projects is 99 €, which corresponds to a daily rate of about 791 € based on an 8-hour working day.
Of the freelancers who have used C++ in their recent projects, 83% hold at least a Bachelor's degree, 52% hold at least a Master's degree, and 13% hold a doctorate.
On average, freelancers who have used C++ in their recent projects have 23 years of professional experience, with a single engagement typically lasting around 3.3 years.
