It has a brand, a model, a generation (sometimes), a version and its set of technical specs. We can match each version by brand, model, generation and then version name. Whatever technique you use, what matters is the result. Please reach out to discuss the subject. Kind regards

Bonjour, peut-être qu'avoir un collaborateur français aiderait pas mal ? ;) J'ai un doctorat en Sciences et suis spécialisé en analyse de données. Je travaillais au CNRS auparavant et suis maintenant analyste freelance (déclaré, avec Siret). Je serais heureux de collaborer avec vous, puisque votre projet rentre tout à fait dans mes cordes. Je ne sais pas si vous avez déjà essayé d'unifier des bases de données dans des équipes de recherche... Je suis expert en R (j'enseignais R à la fac) et me ferais une joie de mettre mes compétences à votre service !

Hello, Je me permets de vous écrire en Français car votre start-up est française. Je suis un administrateur de base de données Oracle expérimenté et en tant que tel, je pense pouvoir vous aider. Toutefois, il faudrait clarifier l'objectif du travail. A ce que je comprends, il s'agit de nettoyer les données avant de les charger dans une base SQL car certains champs seraient dupliqués ou bien il y aurait des doublons. Je vous prie de m'informer plus sur ledit objectif. Dans l'attente de votre réponse prochaine, veuillez recevoir mes cordiales salutations. Christian E. Kuoh

Experience in Data Science  Analyzed sales data, CRM data for a waste management company. The work included understanding the features of all the relevant datasets and how it is linked to the business processes. It included data preparation, drawing insights from it and presenting it to the client on a regular basis.  Worked on a route optimization problem for a waste management company. Analyzed the existing routes of all pick-up vans and identified routes that needs to be re-routed. It also involved visualizing all pick-up points based on different features on a Google map and identifying anomalies with respect to the current routes. This was done on R using R’s geospatial packages and Google API. Clustering algorithm was used to suggest optimal clusters of routes and suggest route modifications.  Worked on data visualization on R Shiny package for representing different dimensions of data which can be dynamically shown to the end user.  Data analysis of unstructured data in the form of customer feedback/complaints/notes. Data analyzed to identify customer sentiments, service delivery issues, product related issues and pricing issues. This was done using R’s text mining packages.  Data modelling experience using algorithms such as logistic regression, multivariate linear regression and cluster analysis.  Analyzed data for a Jewelry store by mining data from their social media sites. This was done using R’s data mining packages.
