Making your complex work
easy to understand.

I help you bridge the gap between deep complexity and clear audience understanding. I provide the visual clarity and analytical support needed to ensure your work is recognized.

Areas of Expertise

01

Exploratory Analysis

Your data has more value than standard plots and summary statistics reveal. I find the signal in the noise by uncovering patterns, hidden trends, and anomalies in your raw datasets using Python and R, and SQL.

02

Presentation Design

The presentation is often the only visible part of your work. I design clean, well-structured slides that accurately reflect the complexity of your research while making it accessible to your audience.

03

Data Visualization

The greatest value of a picture is when it forces us to notice what we never expected to see. I design clear plots and dashboards that allow the data to speak for itself, making complex patterns apparent.

04

Open Source Intelligence

Basic search and AI summaries lack nuance. I build a complex, verified picture from fragmented information, identifying the specific intelligence that you can use for making decisions.

05

Statistical Modeling

All models are wrong, but some are useful. I build interpretable predictive models that prioritize practical utility, helping you validate hypotheses and forecast outcomes with confidence.

Václav Petrák Profile Picture

Václav Petrák

I am a data specialist with a background in biomedical engineering. I focus on modeling, statistics, and complex data analysis. I have spent over a decade in academic and industrial R&D, working on ophthalmic and material science projects. I have gained recognition for my analytical and visualization skills.

For the past decade, I have been active in teaching students and fostering interdisciplinary collaboration within the scientific community. I often served as a bridge between researchers from different fields.

During my career, I have seen excellent ideas go unrecognized due to unclear communication, poor visualization, or cluttered slides. Experts tend to have a deep knowledge of their work but often suffer from the "curse of knowledge"—they forget what it's like for outsiders not sharing their insights. I solve this by creating designs that respect the complexity of your data while guiding your audience to the correct conclusion without ambiguity. As a generalist, I offer more than just design. I provide the analytical backbone your project needs—from cleaning complex datasets and building statistical models to gathering verified intelligence.

Impact & References

Let's give your data the clarity it deserves.

Whether you have a complex dataset that needs decoding or a high-stakes presentation that needs structure, I can help you find the signal in the noise.
