About me

Hi, I'm Marcin. I blend 20+ years of Big Tech leadership (Google, Marqeta) with the creative power of an "AI-Powered Author."

As a manager, I built systems and led teams. As an author, I've published 14 novels, writing ad copy that sells.

I deliver:

B2B Tech/FinTech Content: Case studies, whitepapers, and blogs. I know the jargon from working at Marqeta.

E-commerce QA Audits: I'll find the money-losing bugs on your site (especially payment flows) before your customers do.

"Native Check" (PL-ENG): I make your pitch decks and proposals sound like a native US speaker (I worked/lived in the US).

AI Graphics & Video: Book covers, professional headshots from selfies, and short TikTok/Reels ads.

AI-Assisted Technical Translation: Fast, accurate, and context-aware.

I'm not just a freelancer; I'm a senior-level problem solver.
