Paul in wenigen Worten

Data Scientist,

I am a product driven data scientist. This means that I consider above all, your business.

My mission is to help you make the most out of your data. My core value is to consider data science projects from end to end. I deliver production ready products, from building a data platform to the fine tuning of machine learning models. My skills are between a Pure Data Scientist and a Backend Developer.

This is what I can do for you:

- Evaluating where data can improve your business
- Optimize your KPIs with algorithms and machine learning models
- Set up a software architecture to allow your data scientists to bring algorithms to production
- Creation of a data pipeline or a Data Lake
- Training your teams on machine learning and data engineering.
- Audit that your software architecture is GDPR compliant.

French version:

Je suis un data scientist orienté produit. Cela signifie que je considère avant tout chose, votre entreprise.

Ma mission est de vous aider à tirer le meilleur parti de vos données. Ma valeur fondamentale est de considérer les projets data de bout en bout. Je livre des produits prêts à être mis en production: de la construction d'une plate-forme de données, à la mise au point de modèles de machine learning. Mes compétence sont à mi-chemin entre un Data Scientist et un Developer Backend (Java, Python).

Ce que je peux faire pour vous :

- Identifier comment vos data peuvent améliorer votre entreprise
- Optimiser vos KPI grâce à des algorithmes et des modèles de machine learning
- Mettre en place une architecture logicielle pour aider vos Data Scientist à mettre en production de nouveaux modèles
- Création d'une data pipeline ou d'un Datalake
- Formation de vos équipes au machine learning et au data engineering (Formateur AI).
- Audit de la compliance à la loi RGPD de votre solution logicielle.

Senior Research Scientist

Berlin, Allemagne

Januar 2018 - April 2020

As a Senior Research Scientist, I was responsible for building the architecture for Zalando's logistics algorithms. The data teams where organize to deliver production ready products. Therefore, I always consider algorithms and machine learning models in the perspective of improving the business.

The key product, I worked on was optimizing how the customer orders are processed together to improve the productivity of the warehouse. The first part of the project was to split a monolith into a micro service architecture to facilitate the creation of new algorithms. By doing this, we could introduce technologies such as Spark and Gurobi to help us create a new generation of logistics algorithms.

Zalando SE


Algorithmic Software Engineer

Berlin, Allemagne

September 2014 - Januar 2018

As an Algorithmic Software Engineer, I was responsible for:
- Understanding the business requirements and translate them into KPI and mathematical models.
- Design an algorithm that would optimize the KPIs.
- Build a software that could run the algorithms in production.

The key product I worked on, was relocating Zalando's stock in a predictive fashion in order to have "The right stuff at the right place". Mathematically speaking this was trying to solve a stochastic version of the news-vendor problem. We were able to solve the problem optimally because of a specific graph structure. We also developed a demand forecast prediction model using a variation of ARMA time series.

    Salomé Santos - Zalando


    I’ve worked with Paul at Zalando for many years and in different teams. Paul was a reliable colleague, a task that he took he saw it finished and looked for a good solution for it. He is driven by data results: over the years I saw him pushing for decisions to be made based on thorough investigations. Paul not only is an analytical person, but he is also quick to implement and his code is of good quality.

    Roberto Trunfio - Appway AG


    I had the pleasure to work with Paul for a couple of years while both working in Zalando SE, in the same team. Paul always shown a positive attitude, very oriented towards the problem solving. He was very keen to learn new technologies and apply the scientific method to any problem he had to tackle. Moreover, he proved to be able to face production issues with professionalism and pragmatism. For sure, his knowledge of Statistica and Data Science helped a lot when coming to new solutions for problems related to big data analysis and resource optimization. Last but not least, he was also a very nice person, always polite and friendly, bringing a positive mood in the team. In short, he is one of those that makes your daily worklife enjoyable even in the worst sistuation.
