The most amazing... I've created is a FIX engine in Erlang which runs as a cluster and communicates with other programming languages via RabbitMQ.
  • Risk Analyst and Developer
    2014 - PRESENT
    GIC Private, Ltd.
    • Created a fully automated batch reporting and analytic engine for weekly and monthly reports. The analytical layer is written in Python with Pandas, NumPy, and SciPy API. The analytical engine is linked with various front-ends like Excel (using some VBA) and TIBCO Spotfire. The VBA front-end was written by me.
    • Built an internal website using a Python Django-based web framework to enable users to view the reports.
    • Wrote utility apps using C# to provide the operations team with the ability to encrypt and decrypt their credentials and read the configuration file from Excel to run on-demand jobs.
    • Developed Fix-Engine in Erlang.
    • Built a market data framework using RabbitMQ.
    • Supported a C#-based GUI.

    • Understood the procedures followed daily by the energy traders sheets (contract rolling, vol-marking, etc.) used by various traders to provide a better automation process using VBA, C++, and Haskell scripts and faster response time.
    • Developed a framework to be used on top of the Excel development SDK for creating an easy-to-use Excel add-in with C/C++. The add-in uses market data APIs from Reuters and Bloomberg. The whole package uses various design patterns for creating efficient and reliable code.
    • Did end-to-end development involving the creation of an installer using NSIS and an open source Haskell library (NSIS). Wrote automated scripts to fully automate the deployment process.

  • High-Speed Database (Development)

    The project, for a hedge fund, involved creating a fault-tolerant database for a live currency feed. The challenging part of the project was that it needed to be both fast and fault tolerant. That's where Erlang played a pivotal role for us (two developers). We used Erlang's built-in Mnesia with some clever optimizations and linked them with PG-SQL. The result was a brilliant piece of proprietary code with stability, scalability, and speed.

  • Risk Reporting and Analytical Framework (Development)

    This project, for a famous wealth fund, involved creating a reporting framework with Oracle in the back-end, Python (Pandas, NumPy) for analytic functions and data cleaning layer, and Tableau, TIBCO Spotfire, Excel, and a web service (Python-Django) for the front-end. The framework is entirely designed and maintained by me.

  • Monte-Carlo Simulations (Development)

    Designed a Monte-Carlo method to price various kinds of exotic and plain vanilla options using variance reduction techniques such as antithetic variables, control variables, and Brownian-Bridge to get more accurate results.

  • Physics Exam Preparation Site (Ruby on Rails) (Development)
