I help companies prepare, design, review or move data and BI projects forward so they lead to usable, understandable and sustainable outcomes.
I can help with problem analysis, solution design, data architecture, data warehouses, BI reporting, supplier assignments, expert delivery oversight or the design of a more advanced analytical solution for a specific business area.
Many data and BI projects do not start failing only during implementation. The issue often appears earlier: in an unclear goal, weak assignment, different understanding of metrics, unsuitable data model, poorly chosen architecture or insufficient communication between business, IT and suppliers.
Technology matters, but it is not enough on its own. For a data project to bring value, it must be clear what problem it solves, what decisions it should support, what key numbers mean, where data comes from and how the solution should remain sustainable over time.
My role is to help clarify these points, design a practical solution and keep attention on an outcome that will truly serve the company.
You are preparing a new BI or data project.
Reporting is growing but becoming harder to navigate and trust.
Leadership wants better numbers, but it is not clear what that actually means.
You need to design or review a data warehouse, datamart or analytical layer.
A supplier proposes a solution and you need an independent expert review.
Business, IT and the supplier understand the project goal differently.
You have data in multiple systems or companies and need to connect it meaningfully.
You need to prepare an assignment, roadmap or architecture for the next phase.
The project is already running but needs a direction check or correction.
I help name the real problem, place it in business and data context and design a practical next step.
We typically clarify:
what the real problem is and what is only a symptom,
what decisions the solution should support,
what data, systems and teams are involved,
where the main risks are,
what next step makes sense.
The result may be a solution design, high-level roadmap, recommendation for the next phase or an assignment for an internal team or supplier.
I help design or review the architecture of a data solution so it is not only technically possible, but also understandable, sustainable and usable for reporting and decision-making.
Typical topics:
roles of source systems, DWH, datamarts and BI layer,
analytical layer design,
links between systems,
work with history and structural changes,
connecting data from multiple systems or companies,
data model design,
long-term sustainability and scalability of the solution.
The point is not only to “build a data warehouse”. What matters is that it has a clear role in the company’s overall data architecture.
I help design reporting and the analytical layer so outputs are not only visually attractive, but mainly understandable, usable and trustworthy.
We typically work on:
what decisions the reporting should support,
which metrics and dimensions truly matter,
how KPIs should be defined,
how to build the data model for reporting,
how to design dashboards and reports,
how to separate operational reporting, management views and deeper analytics,
how to avoid a situation where many reports exist but provide little real support for decisions.
I help prepare assignments for internal teams or suppliers, review solution proposals or continuously oversee whether the project is moving in the right direction.
I typically help to:
formulate assignments so they are understandable from both business and data perspectives,
split the project into practical steps,
review supplier proposals,
highlight risks in architecture, metrics or data,
support communication between business, IT and suppliers,
continuously correct project direction.
This form of support is especially useful where a company does not want to be fully dependent on a supplier’s view and needs its own senior data perspective.
In some situations, it makes sense not only to design data or BI architecture, but also to prepare a more advanced analytical solution for a specific business area — for example sales, client retention, process performance or operational data.
This is not an off-the-shelf product and not a standard dashboard. It is an individual project that needs to be embedded into the data, reporting, processes and systems of a specific company.
It may typically include:
data and process analysis,
design of analytical logic,
data model design,
backend built on SQL Server or another suitable platform,
connection to the existing reporting environment,
recommendations for decision-making or activity management,
ongoing maintenance and development.
More specialised solutions, for example for B2B sales or client retention, make sense to address separately based on the data, processes and commercial context of a specific company.
The budget depends on scope; more advanced analytical solutions typically start from higher hundreds of thousands CZK and may reach several million CZK.
A well-prepared data or BI project has a much higher chance of bringing value. Not because the right tool is selected, but because the problem, goal, data model, meaning of numbers, architecture and next steps are clearer.
Typical benefits of cooperation:
clearer assignment and lower risk of a poor project start,
better connection between business needs and the data solution,
clearer meaning of metrics and KPIs,
more suitable data model and architecture,
higher chance that reporting will be truly usable,
early detection of risks in data, assignment or supplier proposal,
better communication between business, IT, data teams and suppliers,
more practical roadmap for further development,
lower risk of creating an expensive solution the company cannot rely on.
Data and BI projects differ by goal, phase, scope, number of systems involved, availability of people and expected output. This cooperation is therefore usually priced based on the specific situation.
Typical scope may include:
| Form of cooperation | Suitable for | Fee |
| Project consultation | quick expert assessment of a specific question | CZK 7,000 / hour |
| Consultation package | clarification of the problem, risks and next steps | CZK 70,000 / 12 hours / 3 sessions |
| Analysis and solution design | concrete analytical or design work | based on scope |
| Architecture / DWH / BI design | preparation or review of a larger solution | based on scope |
| More advanced analytical solution | individual analytics for a specific business area | based on scope, typically from higher hundreds of thousands CZK |
Fees are listed without VAT where VAT applies.
For project work, it is important to first distinguish whether you need quick assessment, a design phase, expert oversight or concrete delivery. Based on that, the scope, form of cooperation and responsibilities are defined.
1. You describe the situation and goal
We start with what the company is dealing with, why it matters and what phase the project is in.
2. We clarify what help you need
We distinguish whether consultation, analysis, solution design, architecture, delivery oversight or a concrete analytical solution makes sense.
3. We agree on scope and output
We clarify what the result should be: a decision, assignment, roadmap, architecture design, data model, reporting layer, direction check or delivered analytical solution.
4. We work on an outcome that serves the company
The goal is not to deliver only a document or dashboard. The goal is to move the company towards a solution it can practically rely on.
Send me a short description of what you are dealing with, what phase the project is in and what result you need. Together, we will choose the right form of support — from consultation through solution design to expert oversight or preparation of more advanced analytics.
