Bio
Victor Touchet
Simon is an awesome person to work with: he is cold blooded under pressure, analytical in problem solving and always keen to tackle tricky technical issues. He is also a good teacher with very good pedagogical skills. I hope to have the chance to work with him again in the future!

I worked with Simon for the last 3 years. The first one, we worked in an advertising company called Powerspace and thanks to his ability to understand how the business worked we have been able to develop critical product improvements for the company. The last two years, we co-founded and worked together on an ambitious startup aiming at changing the way people are traveling in Europe. Indeed, with a 99€/month subscription, Hewago is a game-changer in the air industry and first on his market. During this experience, Simon had to have an exponential learning curve since he was the only developer of the company. He had to master frontend tech like angular as well as backend tech like java but also data algorithm in python and api connections to our partners. Simon learned all the technical knowledge needed to do his part in an incredible low amount of time. I recommend Simon for every project you can have.

Took part in 32 missions with clients such as RTE, Orange, EDF R&D, ERDF, Engie, Société Générale, HSBC, BNP Paribas, Cétélem, Prisma Media, IPSEN, PMU, Total... I've been accustomed to :* Brainstorming with business representatives and generate data science use cases that will directly impact the company’s ROI. This aspect requires a great deal of creativity and the capacity to translate business insights into machine learning questions. * Building efficient algorithms (ensembling methods, grid-search and other meta-parameters optimizations, features encoding & hashing tricks...) using a wide range of tools (python anaconda, R, Spark, vowpal wabbit)* Designing scalable and down-to-earth architectures to run the algorithms in production, which is often quite different from the advertised solutions (Spark, Hadoop...). * Public speaking in conferences such as the Hadoop Summit or the OpenWorld forum* Training people as Data Scientists, with a course i created * Recruiting the right peopleDuring these years i also cultivated a wide vision of the Big Data market in France, working with top players in various sectors (industry, energetics, telcos, personal finance, retail banking, advertisement and medias, public sector...). These experiences helped me to debunk the myths of Big Data and to build efficient strategies for my clients to become Datadriven. Show less
