The First Creddot

http://www.firstcreddot.com
A Node.js financial forecasting suite for banks, investors, and credit companies. As a co-founder, I developed the entire project from scratch, from the front end to the back end and from the database to the infrastructure.

Based on the last three years of a company's financial statements along with well-known market indicators such as GBP and a qualitative analysis (Porter's Five Forces), the application is able to predict a company's performance up to the next 20 years.

Users have the option to display KPI prediction data in a tabular form (similar to Excel) or as a fully customizable dynamic chart. The user can also export the data in a beautiful and colorful financial report that's automatically generated based on the data entered.

CloudCopy.cc

http://cloudcopy.cc
This free file-sharing service was developed in a month, thanks to significant reuse of code and a Meteor boilerplate I had developed. The site allows anyone to share a file of up to 10GB with multiple users through a simple URL. Downloaders do not need to register.

Discrete Elements Method (DEM)

http://dem.naschpitz.com
A DEM simulator comprising a Node.js and React web interface and a multi-GPU, C++, and OpenCL math engine. It is intended to simulate particles (e.g., liquid, air, granular, or powder) interacting with solid objects and then analyze the forces that act on them. As a practical example, it can simulate a wind tunnel: When a mass of air is thrown at a constant speed at an airfoil, data such as drag and lift can be extracted.
