Senior Software Developer

Building systems
that actually ship.

I'm Daniel Kasprzyk — a developer from Silesia, Poland with 5+ years of professional experience. Been exploring and experimenting with Generative AI for the past 3 years — for the last year building commercial GenAI solutions. After hours I build my own products: from SaaS to personal assistants to standalone tools.

About

Who I am

Senior Software Developer from Silesia, Poland. 5+ years in the industry. 3 years exploring and experimenting with Generative AI, last year building commercial GenAI solutions.

Day job: building enterprise multi-agent AI on Microsoft Agentic Framework. After hours: working on Rezme (AI-powered CV platform), a personal voice assistant, and open-source tools like Whisperio — standalone utilities that solve real problems.

Looking for people building AI projects, potential collaborators, and good networking in the space. Probably have ADHD or too many free tokens on Claude. 😅
