SITE INFORMATION
Legal Notice.
Last updated: 19 September 2026
Website operator
This personal professional portfolio is operated by Marcin Czernecki, based in Katowice, Poland. Contact: work@mczernecki.pl.
Purpose and accuracy
The website presents my professional background and selected contributions to software projects. It is informational and does not itself create an employment, consulting, or other contractual relationship. Any engagement requires a separate agreement.
I aim to keep the information accurate, but project descriptions are summaries and may describe historical technologies or roles. Please contact me to confirm details relevant to a particular engagement or report an error.
Employers and client projects
The employer strip identifies companies I have worked for. Client projects identify work carried out as part of the stated employer's team; they do not imply that those clients engaged me directly or employed me.
Project descriptions refer to my contributions, not sole authorship or ownership of the underlying products. Independent projects are identified separately. Company names, trademarks, logos, and third-party images belong to their respective owners. Their appearance here does not imply endorsement of this website.
Content and permitted use
You may view this portfolio and share links to it. Unless otherwise indicated, my original text and site content are protected by applicable intellectual-property law. For reuse beyond what the law permits, contact me for permission.
Third-party photographs and artwork remain subject to their owners' rights. Where provided, image credits appear with the corresponding projects. Open-source software and fonts are governed by their respective licenses; this notice does not override those licenses or statutory exceptions.
External websites and availability
External links are provided for reference. I do not control third-party websites, their content, or their availability. This site may also be temporarily unavailable or updated. Nothing in this notice excludes or limits rights or liabilities that cannot lawfully be excluded or limited.
