OUR TEAM

I co-founded CORE Law together with Bartosz Pilc, to build a consultancy firm that embodies the principles I deeply believe in—a firm whose services I would personally seek out if I were in our clients’ shoes. Our team is not only proficient in legal area but also deeply attuned to the business realities our clients face, delivering actionable solutions and genuine added value. We approach every engagement as partners, with honesty and full commitment. I reject legal and tax opinions that, while technically correct, fail to provide clear answers or guide our clients toward decisive action.
Over the course of more than 15 years of professional experience, my expertise has broadened significantly, now encompassing corporate law, M&A contracts, data protection, cybersecurity, IT contracts, compliance, and marketing law. In recent years, I have increasingly supported clients in high-stakes business negotiations.
I manage teams of seasoned lawyers and personally oversee the most critical client projects. My strengths lie in navigating change and pioneering new solutions. Diligence, extensive knowledge, unwavering commitment, and an unrelenting drive for continuous improvement are the traits that define me.
As a legal advisor and businessman, I bring a wealth of knowledge and experience to your organization. But first, I will listen—ensuring I fully understand your needs before proposing the best way forward.

In my daily practice, I prioritize building close relationships with clients, embracing a human-to-human approach, engaging in open dialogue, and striving for solutions that effectively bolster business objectives. I’m firmly convinced that legal services must deliver added value and propel clients forward in achieving their commercial goals.
For over a decade, I’ve been at the forefront of managing risk stemming from legal challenges and information security threats. I’ve successfully executed hundreds of projects in marketing and data protection. These ventures demand not only pure legal expertise but also astuteness, strategic foresight, familiarity with emerging technologies, and a deep understanding of contemporary business challenges. My portfolio spans marketing initiatives, email campaigns, marketing automation processes, GDPR implementations, data protection contract negotiations, incident response procedures, and application development. Many of these projects are international in scope, requiring fluency in foreign language and comprehensive grasp of multi-jurisdictional regulations.
I regularly collaborate with board members, marketing directors, data protection officers, CMOs, Heads of Growth, and team leaders in marketing agencies. Specializing in marketing law, data protection, and e-commerce, I focus on problem-solving rather than problem-creation. My clients benefit from my active support as an integral member of project teams. I negotiate contracts, audit websites and applications, analyze risks, craft legal content and terms of service, as well as internal policies and procedures related to personal data protection. I also frequently share my expertise through speaking engagements at industry conferences.

I am a trainee legal counsel specialising in data protection, with a particular focus on the education sector.
I started working in data protection relatively recently, which I consider an advantage. It enables me to approach existing processes with a fresh perspective, ask the right questions and assess how they operate in practice, rather than simply relying on established ways of working.
I see data protection as an area where law, technology and people’s day-to-day work come together. For this reason, I am interested not only in the legal requirements themselves, but above all in how they can be translated into practical and workable solutions.
In my work with clients, I place particular emphasis on clear communication and a pragmatic approach. My aim is to ensure that clients understand not only what their obligations are, but also what steps they should take in practice, in what order, and how to implement them without creating unnecessary complexity in their day-to-day operations.
