Presentation

I am French with a Post Ph.D in Machine Learning1. Furthermore I love web programming and design.

I am currently working remotely for Cisco Security team as a Clojure Software Engineer.

Previously I worked for Vigiglobe. The first six months I worked with node.js (API/MongoDB/Web). Then we upgraded our stack to Clojure, Haskell, Mesos, Kafka, Druid, etc... At that time we were two to make all technical decisions. In the end we made a real time analytics of social media content on a scalable architecture. Actually our architecture is able to manage (Aggregation & Machine Learning) thousands of messages per second.2 In particular, I've written an Haskell twitter stream absorber able to handle thousands of tweets per seconds. And I coded myself a real time sentiment analysis module taking algebraic properties into account to optimize its efficiency.

  • During my Ph.D. I made a C++ program (github3 and resume4). I coded most of standard HMM learning algorithms. I developed an algorithm which I invented during my Ph.D. which use some operational optimization algorithm. During this period I published articles in international conferences and I taught Computer Science to college students.

  • At the Hubert Curien Laboratory I made my post Ph.D. I developed a scientific application in Java/applet/JWS that should be used by biologists. The code has been updated a bit since my 6 month post Ph.D5.

  • I worked in the web industry for Airfrance. My work environment was quite heterogeneous. From shell scripting to manage huge amount of data, web design and production environment.

  • I worked for GridPocket (I am a co-founder). This is a French startup specialized in Electric Grid. I created a private6 web application.

  • I've also written an iOS application to manage passwords7.

  • I am the author of some quite popular blog posts8.

For an almost exhaustive list of my projects, you could check my github account: github.com/yogsototh

Public things done

  • Cisco (threatgrid) Security & Threat Management.
  • Vigiglobe architecture able to analyze thousands of social media messages in realtime. In particular, real time Machine Learning & Statistics.
  • Gridpocket web services (from conception to realization, works in correlation with a mobile app)
  • DEES: a 10.000 line C++ command line program. This program implement most HMM standard algorithms & inference algorithms.
  • SeDiL: a Java application using Swing UI. The goal is to provide biologist an easy way to use an algorithm that generate Similarity Matrices for strings but also for Tree structures. Most graphics was done by me, including the drawing of trees. I didn't used a library for that purpose.
  • YPassword iOS application
  • YPassword web interface in elm
  • Also relative to YPassword ; a Dashboard Widget, a command line tool.
  • Some websites: yannesposito.com
  • Written a thesis in Machine Learning and published in major international conferences: [ICALP 2003], [COLT 2004] & [COLT 2006].
  • A full javascript web application which display Electric consumption in real time.
  • mkdocs (the engine I use to create this document. I exported it in HTML, PDF (using \LaTeX) and SVG.
  • some Mac OS X screensaver, a MetaPost plugin to draw Automata, an RFC-like document to help my student to make a TOR like network, etc...
  • a bunch of other projects see http://github.com/yogsototh
