- the frontman of Rybičky 48
- a digital marketer and AI builder
I loved Lego as a kid. Then AI came along and I started building again — this time marketing systems that deliver results.
I create, therefore I am

Marketing Frameworks
I went through 68 marketing frameworks looking for a documented case behind each one - only 116 of 476 combinations have published evidence. The app picks a stack for your business and audience and builds an LLM prompt: concept, your approval, finished copy. Every claim links to a source; anything unproven the model is not allowed to say.

Currently building. A personal knowledge system on the PARA method - lives in iCloud, capture from my phone in seconds. No server, just files + an AI agent looping over my own context.

Pomodoro Beat
A vibecoded app combining two things I love: music and the Pomodoro technique. The default block is 90 minutes, and the music (a YouTube stream or your own file) plays only while you work. At the end a signal sounds, the music goes quiet, and the break starts on its own.

Rétor
A daily communication trainer. 16 micro-lessons built on frameworks from workshops I attended (GAME, the pyramid principle, elevator pitch, coaching questions): theory, a quiz, a drill and a micro-action for the day. Streaks and XP keep the habit going. One HTML file, no framework.

Johnny
My own local AI assistant on a Mac Mini M4. Started as a chatbot, grew into a full local stack - Ollama + Open WebUI, RAG over markdown, cron agents (a morning AI digest, daily ideas to Telegram) and a custom Mission Control dashboard. Built with zero prior server experience; I document the dead ends as war stories.

VideoEdit24.com
An automated video-editing service. A fast experiment: from idea to a working service, testing the demand.
„Give the work structure, measure, learn from the results - and repeat. Nothing magic, just an honest loop.“
I am a marketer who thinks like an engineer. For fifteen years I have built marketing as a system - from strategy through acquisition to teams and numbers.
Results-focused
I do not care about activity for its own sake. I care about what moved - leads, conversions, revenue.
T-shaped
I understand the whole of marketing and go deep where it pays off the most. I connect strategy with execution.
Ownership mindset
I own things end to end, from idea to outcome. I do not wait for a brief - if something is needed, I build it.
Now and then I write about why I built something.

Chrome profiles don't share bookmarks. I used Floccus.
Personal and work Chrome on one Mac keep separate bookmarks. Google sync won't merge them. xBrowserSync from the Store no longer runs; Floccus plus Drive does.

Why I built Marketing Frameworks
I went through 68 marketing frameworks. Only 24% of combinations have published evidence. So I built an app that picks a framework and polices what AI is allowed to claim.

I can think marketing through and do the work myself. If you want someone who builds you a system, not a slide deck, say hi.
