The most amazing...

...software that I've built is a complex analysis tool used by quantitative analysts for backtesting and evaluation of alpha models during portfolio construction.

    • Designed and implemented a complex analysis tool used by quantitative analysts for backtesting and evaluation of alpha models during portfolio construction. The core application engine was based on principles of Reactive (Rx) and Dataflow Programming. Worked as a sole developer in a team of four - together with two quantitative analysts and data analyst. The project was enthusiastically received and in turn it became the primary research tool used by several analysts.
    • Developed a tool used by portfolio managers for managing portfolios cash flow. It was a C# application with WPF user interface and WCF back-end service connected to SQL Server. Worked as main implementer in a team of three - together with second developer and portfolio manager. The tool was met with very positive feedback as it greatly simplified daily workflow of PMs.
    • Implemented parts of a research tool used to identify and measure performance of various themes in the market, according to complex user-defined criteria. Worked in a team of five - together with two developers, a data analyst, and a portfolio manager.
    • Verified and optimized multiple financial models created by quantitative analysts in SQL, Matlab, and R.

    • Created an innovative semantic faceted search engine as a part of my master's degree thesis. It was developed in Python and C# with PostgreSQL database.
    • Co-authored the relational database schema aimed at efficient storage and querying of parsed scientific articles.
    • Worked on collecting, parsing and preprocessing of scientific data from various sources.
    Technologies: Mercurial, PostgreSQL, Python, C#


  • Nadapa

    Nadapa is a small utility library that can be used for extracting DateTime objects from natural language text.

    It is written in F# with the use of FParsec parser combinator library.

    I implemented this simple library mainly to learn about building parsers with parser combinator library FParsec.

  • Tabular Data Helper

    Tabular Data Helper is a small utility useful for comparing tabular data extracted from different sources.

    During my last job, I had to deal with tabular data from various sources on semi-regular basis. Because of that, I have created a simple utility to scratch my personal itch.

    I've created this small utility to I learn more about TypeScript, React, and their interoperability.

  • RDBMS Model for Scientific Articles Analytics

    I co-authored the relational database schema aimed at efficient storage and querying parsed scientific articles. This database was described in the article published in the book titled "Intelligent Tools for Building a Scientific Information Platform."
