C# and WPF Programmer

I'm a software developer having 5 years of software development experience in c#, wpf, mvvm, entity framework, linq, xaml, and to some extent - wix. I also participate in various machine learning and data science competitions hosted on various crowdsourcing platforms such kaggle, topcoder, and innocentive. Until now I've also completed more than 20 moocs from universities such as MIT, Stanford, UT Austin, etc on subjects such as programming, machine learning, data science and others.

It is the installer application that I developed for one of my projects using WiX Toolset. The installer consists of a custom product key dialog and a corresponding custom action to validate the product key. It also includes code for adding and removing registry keys and desktop shortcuts, installing and uninstalling Windows Services, and launching the application at the end of the install process.

This was a simple project to compare the convergence of two regression algorithms i.e. Gaussian process regression (GPR) and logistic regression (LR) using Combined Cycle Power Plant Data available from the UCI repository. The goal was not on analyzing the Power Plant Data but was on observing the performance of the two algorithms on a given dataset.

The program was written using the scikit-learn library in Python 2.7.  Also, matplotlib was used to produce the plots (as shown in the adjoining image).

This was my first Topcoder challenge where the task was to build a code to process a matrix file stored in a text format, store it as a binary file, and also store the transpose of the matrix in a binary format. The goal was to process the matrices as quickly as possible using only the libraries available with the default installation of gcc along with using any data structures as required. I used some simple file processing techniques available in C along with buffer management and an array of a structure variable to store and process the data.

The challenge was launched to support the efforts of the Bill & Melinda Gates Foundation (BMGF) Healthy Birth, Growth, and Development's (HBGD) HBGDki Open Innovation Platform. Later they also launched two similar challenges for processing sparse matrices and matrix stored in a tuple format in a text file.
