    Summary: Part-time job. Teaching courses in the institute of Business Economics at HEG Geneva, where students learn the basics of programming in the field of finance. Description: I set up several new courses, called “Financial Modeling”, “Programming in Python” and “Information Systems”, where student learn the basics of software design and programming in the field of finance. I create most of the content from scratch, including projects, exercises, slides and exams. Many students attending my courses do not necessarily have any programming knowledge: what is sometimes obvious to me might not be clear at all for my students. The challenge for me is to reconsider everything I take for granted, abstract the content as much as possible, and present the concepts in a simple and practical way to students. Helping people to learn something new is to me a wonderful experience. In addition of showing me an enthralling aspect of education, setting up this course has sharpened my teaching know-how as well as my presentation and communication skills.

  • Epfl (École Polytechnique Fédérale De Lausanne)
    Researcher
    Epfl (École Polytechnique Fédérale De Lausanne) Sep 2015 - Aug 2016
    Lausanne Area, Switzerland
    Summary: Researcher in the EDIC Fellowship Program within the field of database systems and data analysis. Work on two projects: 1) ViDa: Design and implementation of a system architecture to compile and execute just-in-time queries in parallel. 2) DaSci: Development of Web application for large data analysis and visualization. 1. Project at DIAS: “Parallel Query Processing for ViDa”Description: I extend the query processing engine of ViDa, a novel data management system offering just-in-time data virtualization capabilities over raw data sources that are treated as first-class citizen. The ViDa system already offered optimized query processing capabilities by using the LLVM compiler to translate incoming queries into efficient machine code, but did not support parallel query processing yet. Therefore, I used state-of-the-art parallelization techniques to design a software architecture that allows operators of the query plan to be executed in parallel and queries to be distributed across different portions of the data. Skills: Raw Data, Just-in-time Compilation, Parallel Query Execution, Virtual Database, C++, LLVM.2. Project at LSIR: “DaSci: Large Scale Textual Data Visualization”Description: The goal of this project was to build a software to help people work with data, so that they could get faster and better insights about their assets. After determining potential bottlenecks of existing software products, I developed DaSci, a software that empowers data scientists with the ability to explore, transform and visualize large amount of unstructured data. This tool provided data storage, machine learning capabilities, and an intuitive processing and visualization environment, while leveraging modern Big Data frameworks, such as Spark, to process and analyze large amounts of textual data. Skills: Data Science, Data Analysis, Big Data, Data Visualization, Machine Learning, Python, Scala, Spark, HDFS/Hadoop, ElasticSearch, JSON.
