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:

About the role
What they build
A BI Developer turns raw data into reports people can use. They design data models, build dashboards, define KPIs, and make sure business teams see the same numbers everywhere. Strong BI developers also improve data quality and make reporting easier to maintain.
- Dashboards and executive reporting
- Data models and semantic layers
- ETL and ELT workflows
- KPI definitions and metric logic
- Ad hoc analysis support
- Report performance tuning
Core skills
A good BI Developer combines data engineering thinking with business understanding. They work with SQL every day, know how to structure relational data, and can translate vague reporting needs into clear logic. They also need to explain trade-offs to analysts, finance teams, and operations stakeholders.
- SQL and data modeling
- Dimensional design and star schemas
- Data warehousing concepts
- Dashboard design and visual storytelling
- Data validation and reconciliation
- Documentation and stakeholder communication
Tools and stacks
Most BI Developer work centers on a reporting stack such as Power BI, Tableau, Qlik, or Looker. On the back end, they often work with Snowflake, BigQuery, SQL Server, PostgreSQL, Databricks, dbt, or similar tools. The exact stack depends on the company, but the goal is always the same: reliable reporting with clear logic.
When a team already has data engineers, the BI Developer focuses more on the business layer, calculated fields, and reusable metrics. In smaller teams, the same person may cover modeling, dashboarding, and light pipeline work.
Typical freelance work
Companies bring in a freelance BI Developer when reporting needs move faster than internal hiring. This often happens during system changes, new product launches, ERP rollouts, or when existing dashboards no longer match business questions. Freelancers are also useful when a team needs help cleaning up messy reporting logic without adding a permanent role.
What good looks like
A strong BI Developer does more than build charts. They ask the right questions, document definitions, and test whether numbers tie back to source systems. They also keep dashboards simple, so business users can trust them and use them without help.
- Clear KPI definitions
- Reusable data logic
- Stable dashboard performance
- Clean handover and documentation
- Accurate source-to-report reconciliation
- Practical collaboration with analysts and stakeholders
Working with teams
BI Developers often work with finance, sales, operations, and management teams. They may join remote for most of the project and come on-site for workshops, data discovery, or stakeholder reviews. In Germany, many clients expect clear documentation and precise communication, especially when the BI setup supports multiple departments.
For companies, this role is best when the reporting scope is defined but the internal team lacks time or specialist depth. For freelancers, the best projects have access to source systems, a clear owner on the client side, and enough room to improve the reporting layer properly.
Frequently asked questions
Key details about BI Developer, drawn from the questions we get asked most.
A BI Developer turns business requirements into dashboards, reports, and trusted metrics. They usually handle data modeling, SQL logic, KPI definitions, and the reporting layer in tools like Power BI, Tableau, Qlik, or Looker. In many projects, they also clean up broken report logic and make existing outputs easier to maintain.
Look for strong SQL, data modeling, and a clear way of working with business users. A good BI developer understands how source systems map to metrics, can document definitions, and knows how to build reports that stay fast and readable. Tool experience matters, but the ability to translate business questions into reliable logic matters more.
A BI Developer sits between the two. Compared with a data engineer, they focus more on the business-facing reporting layer and less on large-scale pipelines. Compared with a data analyst, they build the reusable structures and dashboards that others use, instead of mainly doing one-off analysis.
A freelancer makes sense when the need is project-based, urgent, or tied to a change like a new ERP, CRM, or data warehouse rollout. A BI Developer freelancer is also useful when you need specialist support for a specific tool or a reporting cleanup, but not a full-time team member. This is often faster than opening a permanent role for a short or uncertain scope.
Expect working dashboards, defined KPI logic, data models, and documented report structures. Depending on the project, the BI developer may also deliver validation rules, semantic layers, and a handover guide for internal teams. Good delivery is not just the report itself, but also the logic behind it.
Most BI Developer work can be done remotely because the main tasks are in data platforms and reporting tools. On-site time can help at the start of a project, especially for workshops, access discussions, or aligning on business definitions. For clients in Germany, mixed setups are common when several departments need to agree on the same numbers.
Ask for examples of how they handled messy source data, changed KPI definitions, or improved a slow dashboard. A strong BI Developer can explain their design choices clearly and show how they checked accuracy against source systems. If they only talk about visuals and not about logic, modeling, and validation, that is a warning sign.
Often yes, but the scope depends on the team. Some BI developers focus mainly on the reporting and semantic layer, while others also build ETL or ELT workflows and dimensional models. If you need both, make the boundary clear before the project starts so the freelancer can plan the work properly.
The average hourly rate for BI Developer is 98 €, which corresponds to a daily rate of about 785 € based on an 8-hour working day.
Of the freelancers working as BI Developer, 89% hold at least a Bachelor's degree, 67% hold at least a Master's degree, and 11% hold a doctorate.
On average, freelancers working as BI Developer have 17 years of professional experience, with a single engagement typically lasting around 2.4 years.
The most common languages among freelancers working as BI Developer are German (100%), English (95%), and French (23%).
The most common industries among freelancers working as BI Developer are Information Technology (81%), Manufacturing (54%), and Professional Services (51%).
The most common business areas among freelancers working as BI Developer are Business Intelligence (98%), Information Technology (96%), and Project Management (58%).
