Freelancer profile translated to English.

Description

Self-taught, passionate about data and automation for over 10 years!

Do you need:

- to clean and/or structure your data

- to better understand your business and/or your customers

- to automate some of your processes

- ...

I am here to:

- advise you in design and formalization

- relieve you of the technical burden

- help you take a critical look at data quality and the resulting figures

- save you time and therefore money (either by automating or by providing you with indicators for more relevant and profitable actions)

I am capable of using several programming languages for my developments. Technical constraints do not scare me; there is always a solution to be found, and I am not afraid to dig deep!

With a general engineering background (specializing in automation and control systems), I shifted towards data analysis and IT development during my first professional experiences.

Having started in this field in small teams, I have always handled the complete value chain, from data collection (Data mining, SQL, NoSQL databases, ...) to presentation (graphs, automated reporting, ...), including analysis and pipeline industrialization.

I therefore navigate between the well-defined roles of: FullStack Developer, Data Engineer, Data Analyst, and I am training to also work in Data Science.

Currently, I am enhancing my skills in Machine Learning and Artificial Intelligence in general. Next, my goal will be to deepen my knowledge of D3.js to create magnificent interactive visualizations!

Generally, I work with Python, NodeJS, the Microsoft Office suite (Excel, Word, PowerPoint, ...) and VBA, but I have also occasionally discovered and used other languages and tools.

Feel free to contact me to discuss your project.
