Hey, I’m Marek 👋

Nerdy millennial who went from geeking out over postmodern lit at uni, through social media marketing and enterprise software, to finding my ikigai as a product marketer for developer-facing startups. Always curious, always learning, and serious about craft.

I recently launched DevPMM, my Substack where I write about positioning, messaging, and storytelling for developer-facing products.

Bringing expertise across product marketing, content creation, social media, and advertising, I combine a flair for strategy and cross-functional collaboration with hands-on, LFG execution.

Below you can check out my career summary and work samples.
