Turning complex data into stories that drive decisions.

A bit about me

I'm a Data Strategist with a thing for turning messy, complex data into something that actually moves the needle. My work spans the full data lifecycle: from building automated ETL pipelines to crafting analytical platforms that help teams make smarter calls.

I've had the chance to work across both Energy and CPG (currently at Nestle), where I've gotten pretty good at bridging the gap between what the business needs and what the tech can deliver. Along the way, I've automated market intelligence workflows processing over 150 million records and built platforms that cut strategic analysis time by 90%.

Right now I'm wrapping up my MSc in Data Science & AI at UTEC and applying my skills in Python, cloud platforms (Azure, Databricks, Snowflake, AWS, GCP), and the whole Power Platform ecosystem. I genuinely enjoy cracking hard problems and helping teams get to the insights that matter.

When I'm not crunching data

Outside of work, you'll probably find me shooting analog film, digging through vinyl crates, catching live shows (and yes, I collect setlists), lifting at the gym, or getting my hands dirty with some light gardening.
