Professional Experiences

  • [Nov 2009 - NOW] Working as a Software Engineer in Google Inc. (the Waterloo office in Canada).
    • [2018 - NOW] Member of the Cloud Genomics team.
      • My responsibilities are around big data processing and storage of genomics data, e.g., DNA variants storage, variant annotation, queries etc. (part of our work is open source).

    • [2012-2017] Member of the Conversion Optimizer team which is an automated bidding management system for advertisers. Summary of my contributions:
      • Design, implementation, and maintenance of computation pipelines and storage solutions for processing massive data-sets of user ad interactions. The published/non-secret technologies involved in this include: MapReduce, Flume (C++ version), BigTable, Dremel (known as BigQuery externally), Spanner, GFS and its successor Colossus.
      • Improving Machine Learning Models (based on Logistic Regression and Poisson Regression) for Conversion Prediction (implementation of new features in the serving stack, running A/B experiments, analysis, etc.).
      • Applying a new novel Machine Learning method based on Bayesian inference and Gibbs sampling to the Conversion Prediction problem (implementing some of the required features in core Machine Learning serving systems used in Google).

    • [2010-2011] I worked on Javascript tooling (in particular Closure Compiler based support in IDEs). The result is an Eclipse and a Vim plugin that integrates the compiler and provides IDE features (auto-completion, etc.). This also involved modifying the Closure Compiler to support hot-swap builds which is already open-sourced.

    • In my first few months in Google, I have also worked on latency-measurement frameworks for mobile web-apps.

  • [May 2004 - Nov 2009] Working in Simulated Biomolecular Systems.
    • I created a new tool called eCrySP for prediction of crystal structures of small molecules as part of PhD research (see PhD thesis).
    • I contributed in the eHiTS docking software package and part of that contribution is included in my PhD thesis (see Publications).
    • I also had major contributions in LASSO and also minor contributions in other products like ARChem (see Publications).

  • [Sep 2002 - April 2004] Teaching and research assistant in University of Waterloo (during my master studies).

  • [Sep 2001 - Aug 2002] Working in the Network Security Center of Sharif University of Technology.
    •  I mainly worked on an Intelligent Web Crawler that finds and classifies URLs.

Other Part-Time Roles

  • [Fall 2000 and Fall 2001] Member of the Scientific Committee of ACM ICPC Regional Contest, Tehran Site.
  • [Summer 2000] Coaching Iran national team in the International Olympiad in Informatics (IOI 2000) in China. (I was one of the three coaches!)
  • [1999-2001] Member of the National Informatics Olympiad Committee.
  • [1998-2001] Member of the National Informatics Olympiad Students Committee.
  • [1998-2001] Chief editor of The Way of Olympiad journal (informatics section).

  • [1998] First place in the 1st Sharif computer dept. internal ACM contest (with my friends S.V. Mirrokni and E. Chiniforoushan), and participating in ACM regional contest.
  • [1998] Seventh place in the ACM regional contest (Dhaka site).
  • [1997] Bronze Medal in IOI'97 (South Africa, 1997).
  • [1997] Beginning the undergraduate studies in Computer Department of Sharif University of Technology without any entrance examination.
    • Remark: In Iran, each year, more than a million students take the global entrance examination for universities and about 10% are accepted. As a reward for being member of national olympiad team, I could enter any university I wanted, without taking this exam. I chose Sharif university of technology and its Computer Engineering Program.
