You can read my blog with more updates here:


  • - NitroEngine - an alternative computational engine to MS Excel that speeds up statistical analysis (ie. Monte Carlo models) significantly.

  • - DataNitro Voyager - the simplest REST API to push data to Excel users and their spreadsheets, without having to touch the Windows/Office stack (currently defunct).

  • - the project I am currently working on. We're replacing VBA in Excel with Python. YCombinator backed startup (S12).

  • Implementation and Performance Analysis of Hash Functions and Collision Resolutions - spring '12 - an implementation project & a paper - performance analysis of different collision resolutions (Linear Probing, Quadratic Probing, Cuckoo hashing and Hopscotch hashing) w.r.t cache performance across multiple cores. The code is available on my github.

  • - winter & spring '12 - a web & mobile app for travel (currently defunct).

  • Parellization of Dijkstra's Algorithm - Dec '11 - a paper on the Relax Heaps data structure; describes parallelization of the shortest paths algorithm to (efficiently) scale across multiple CPU cores.

  • Parallel memory allocator - Fall '11 - a Hoard-like parallel memory allocator for one of my clas ses. See the source here, it's pretty well commented. Provides concurrent (thread-safe) malloc and free and scales reasonably well on multiple cores.

  • Introduction to C++ - Jan '11 - an intro C++ course I taught during the IAP. You can find the study materials on MIT OCW.

  • Skimmedmilk - Dec '10 - a dinner signup hack (website) for one of my dorms. Written in good old php, the code is quite nasty, but hey, it worked. Uses MIT certificates for auth.


  • Excel and IPython - Nov '13 - PyData NYC
  • Python in Excel - 2013 - multiple DataNitro-related talks at our meetups and at NY Data Wizards
  • SkipTrie - Apr '13 - a poster session on my research at MIT EECScon
