Ricardo Schifini

Argentina

My main skills are problem solving, software development, numerical simulations and data acquisition and analysis. I am a very creative person and like to think out-of-the-box. I have strong analytical skills and I like working in groups as well as individually.

I am currenly developing software applied to big data using R programming language. I also contribute to Stack Overflow where I rank in the top 5% for R and Matlab.

I have been developing software and performing numerical simulations for more than 15 years. I have used Matlab for data analysis, Monte Carlo simulations, image analysis and user interfaces. I am currently ranked at the top 20% in StackOverflow.

I'm also an expert in JavaScript, JQuery, HTML and CSS, having developed more than a dozen web apps during the last 3 years.

I have been working for more than twelve years in R&D for the leading supplier of steel tubes and five more during my PhD in Physics.

I am multilingual with mastery in three languages: Spanish (native), English and Portuguese, and competent in French and Italian.

Data Science Leader - Supervielle Seguros

ago. 2020 - actualidad

Currently leading a small but growing team of Data Scientists where we cover all the roles of the trade from data extraction, cleaning, data engineering, analysis and machine learning models. I raised the company's Data Warehouse from an initial sketch into a full fledged one in less than a year. Created 50+ ETL scripts with Python and SQL, machine learning models, data analysis with R and Python and several dashboards with PowerBI. My team is the company's reference for all data related situations.

Mentor / Teacher - Acámica

mar. 2019 - nov. 2019

Mentor in two Data Science 5-month courses. Course topics range from:

Introduction to Python's pandas, numpy, matplotlib and seaborn libraries.

To most used machine learning techniques for supervised and unsupervised learning (Regression, KNN, NLP, Neural Networks, PCA, Kmeans, SVM, and many others).

Senior Researcher - Tenaris

feb. 2003 - may. 2015

Key skills and expertise:

Software development (mostly Matlab):

  • Implemented a statistical routine for obtaining target reliability levels of collapse pressure of tubes
  • Developed Monte Carlo routines for structural integrity calculations
  • Designed and implemented a GUI for finite element modelling of welding lines
  • Designed and implemented a user friendly GUI for measuring samples by image analysis increasing efficiency by a factor of 10.
  • Developed the acquisition software in LabView for a thermal flux measurement laboratory

Laboratory testing:

  • Defined, organized and carried out laboratory tests of plastic thread protectors and rod centralizers
  • Proposed and tested improvements to tube traceability by adhesive labels and RFID
  • Proposed changes to an ENARGAS (Ente Nacional Regulador del Gas) test standard for approving tubular goods for gas transport. Defended Tenaris position successfully.

Mathematical models:

  • Modeled an API ring gauge to determine influence of taper and diameter tolerances for 2014 API standards discussions
  • Avoided a $1.5 million (ARS) claim against Tenaris by simulating the roll over of truck loaded with steel tubes.

Software use:

* Created several 3D models using Dassault Systemes' Catia V5.
