Senior Cluster Lead — Data & Intelligence Delivery, EY

I build the automation that takes enterprise data from raw ERP extraction to decision-ready insight — and I read it with a business education behind me, so the output is a recommendation, not just a dataset.

01 — About

Automation is the part I actually love

I lead the Zurich cluster for Data & Intelligence Delivery at EY, coaching a team of five and owning the data pipeline that audit and advisory engagements run on — ERP extraction, transformation, analytics, and the governance that keeps all of it defensible.

What pulls me in is automation. Every engagement starts with a manual process someone has accepted as unavoidable, and most of them aren't. I've spent four years replacing those with scripted extractions, Alteryx workflows and Python routines that turn weeks of coordination into something repeatable.

"The technical work is only half of it — the other half is knowing what the business actually needs to decide."

That second half comes from my economics and international business background. I studied real estate and investment in Cracow, took an MSc in International Business at ZHAW, and spent a detour in law and psychology before that. It means when a client asks what a finding implies for their close process or their risk exposure, I can answer in their language rather than handing over a dashboard.

The combination is deliberate. Plenty of people can write the query; plenty can run the client conversation. I'm most useful in engagements that need both at once — complex extraction with a stakeholder who needs to understand what just happened, often in German, often under audit deadline.

Engagements & clients

Selected delivery work across Swiss listed and multinational groups — the kind of engagement where the ERP is unusual, the timeline is fixed, and the client needs a person who can do both the extraction and the conversation.

Optimum working environment

I'm well suited to a changing, fast-paced team where there are no ambiguities of leadership and I'm accountable for the results I produce.

I need to work with others — I thrive on the buzz and am likely to become bored working alone. I'm often adept at fast-paced environments where I can act on opportunities as they arise.

What slows me down: no factual, goal-oriented approach; unclear deadlines; lack of resources to reach the goal; and a tech stack that won't allow the automation the problem actually needs.

My personal IKIGAI

Ikigai (pronounced ik-i-gai) is a Japanese concept meaning "a reason for being."

Activities that allow one to feel ikigai are never forced on an individual; they are often spontaneous, and always undertaken willingly — giving the individual satisfaction and a sense of meaning in life.

It sits at the intersection of four questions: what you love, what the world needs, what you're good at, and what you can be paid for.

I first mapped this while finishing my Master's, when the answer pointed towards investment advisory. Four years of building data pipelines later, the shape has stayed the same but the content has moved: the same instincts — systems thinking, creativity, wanting to teach — now point squarely at automation and analytics.

What changed isn't what drives me. It's that I found the version of it where the business education and the technical work reinforce each other instead of competing.

What I love
  • Solving problems nobody has solved yet
  • Discovering new things
  • Travel & nature
  • Piano & swimming
What the world needs
  • A digital, automated future
  • Trustworthy, well-governed data
  • Financial & data literacy
  • Innovation that actually ships
What I'm good at
  • Systems thinking & automation
  • Analytics and data modelling
  • Translating data into business terms
  • Coaching, teaching, people-driven
