Hi, I'm Geoff.

I am a data scientist at Omio (formerly GoEuro), a Berlin startup building an end-to-end mobile ticketing and travel search product. I am also enrolled as a part-time student at Georgia Tech, where I am pursing my MSc Analytics degree with a focus on computational data analytics. Previously I worked as a product manager at a Rocket Internet portfolio company.

I am passionate build narratives around user behaviour at scale using quantitative data. Data is cheap, but actionable insights are scarce. I have spent the past five years working with product teams at consumer tech startups to build coherent mental models of user behaviour and deliver insights which drive the product roadmap. I primarily work in the python ecosystem (NumPy, pandas, scikit-learn) and am passionate about applying machine learning techniques and engineering best practices to the traditional data analysis workflow.

Core values

Clarity – Vagueness undermines personal accountability. It also reduces the signal-to-noise ratio of knowledge within the organization. Saying “I don’t know” is better than equivocating. This takes courage.

Systems-thinking – I believe that outcomes are largely determined by the environment in which they were reached. Assume good intentions, and seek to improve on suboptimal outcomes not by “trying harder” but rather addressing the underlying factors responsible.

Incremental improvement – The most powerfully motivating equation is this: $ 1.01^{365} = 38 $. Sometimes it feels like our contribution is a drop in the bucket, but we can make great compound gains from leaving things just 1% better than we find them on a daily basis.
