About Me

I am a senior associate in the Privacy & Data Protection team in Warsaw.

I've been advising clients since 2007 and specialise in privacy, data protection and ecommerce issues.

I combine a passion for data protection with an interest in unmanned aerial systems, and advise clients on regulatory and privacy issues in this emerging sector.

Over the years I've built up in-depth experience in supporting companies from the construction, real estate, IT, production, retail, and banking and finance sectors. This allows me to better understand the environment in which my clients operate.

Clients appreciate my help with implementing global strategies and business goals, and guiding them through complex rules in data protection law. I advise on implementing the General Regulation on Personal Data Protection (GDPR), and audit companies on compliance with the data protection rules, also in case of mergers or acquisitions, to propose remediation and risk mitigation actions. I support clients with processing HR data, designing data protection systems and internal documentation, conducting data transfers and marketing activities, and creating agreements.

Clients value my rapid response in relation to personal data breaches, especially evaluating incidents, preparing data breach notifications, and representation before the President of the Polish Data Protection Office (PUODO). I'm also closely involved in building strategies for informing individuals about the personal data breach, which includes advising on selecting the communication form, preparing the communication to the data subject, and internal documentation describing data breaches.

I've authored numerous publications on data protection and privacy, and have also been a speaker at many training sessions and conferences.
