Technical GA4 and GTM management, reporting, and insights that help your business grow.
With 3+ years of programming experience, I identify technical errors in your website and analytics setup that others miss.
I ensure your analytics infrastructure is built on solid foundations with reliable, accurate data.
Most businesses unknowingly operate with incomplete, incorrect, or GDPR non-compliant tracking systems.
Making decisions on broken data is worse than no data at all – let me ensure your analytics foundation is reliable and actionable.
GA4's exploration reports are limited and can't handle complex data analysis your business needs.
I build custom dashboards in Looker Studio/Power BI with advanced SQL that give you deep insights GA4 simply can't provide.

I started coding at 15 with WordPress, built through frontend and Flutter, almost three years of hands-on work. When I moved to Brno for university, I landed at a UX agency where a mentor introduced me to web analytics and shifted how I see data and marketing context.
At the agency, I worked with enterprise clients like Kentico and KD, then became a project manager on another project. I handled the full technical marketing stack: GA4, GTM, BigQuery, Looker Studio, and AI. But the real skill is understanding what data actually matters and how to communicate it.
Today I'm freelance and studying both Computer Science and Information Studies at KISK, because programming without context is just code. Understanding how information flows and connects with people is what makes it meaningful.

Braňo enjoys analytics, especially from a technical perspective. He has no trouble mastering technologies such as GTM or SGTM; all you need to do to implement a new platform on the website is send him a link to the documentation. As a bonus, he is also skilled at project management, which is definitely not common among IT specialists.
I worked with Braňo for almost a year and even as a young student he surprised me with his technical skills and level of experience that was higher than one would expect. Even though web analytics was new for him, I saw very fast progress and a strong willingness to take on new challenges. He may seem like a classic “IT guy”, but he can easily surprise you with his communication and project management skills, which makes him a great partner to work with, whether as a colleague or a freelancer taking care of your project.
