Making your data
easy to understand

I help you bridge the gap between complexity and clear audience understanding. I provide analytical expertise and visual clarity needed to ensure your work makes an impact.

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, 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

Predictive 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, focusing on modeling, statistics, and complex data analysis. With over a decade in academic and industrial R&D — specifically in ophthalmic and material science — I have built a reputation for sharp analytical skills and clear visualization.

Throughout my career, I have often served as a bridge between researchers from different fields, fostering interdisciplinary collaboration.

I have seen many excellent ideas go unrecognized due to unclear communication, poor visualization, or just cluttered slides. Experts often suffer from the curse of knowledge, forgetting what it is like for outsiders who lack their specific insights. I break this curse by creating designs that respect the complexity of the data while guiding the audience to correct conclusions. 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.
