MisysJune 2011 - April 2013

Firstly, I developed new functionalities for a top product in the capital markets world: Summit FT. Basically Summit FT has a Client - Server architecture which involves on the client side two applications (Windows Forms application and MFC application). On the server side, there is a number of processes written in C++ which provide real time updates, data authorization and data validation for the client side. Those processes are platform independent because between client and server there is an Apache server which handles requests between those entities. My area of expertise was on the Back-Office module where I developed some components which were able to handle external data from different systems and message queues like IBM Websphere. Mostly, external data means transactions exported from different system in XML format or FPML format (Financial product markup language). On the functional side, I worked on various scenarios which involved processing external data in real time in order to measure financial indicators.
Another technical challenge was to improve the way Summit interacts with external data. In this case I`ve built an application where users can visually map XML messages with Summit internal entities.
Secondly, I was involved in developing internal tools to enhance features like continuous integration, code complexity and code review. This was a great opportunity to learn how software with large code base can be maintained in order to be shipped on time. I developed a solution which integrates Bug Management System (JIRA), source control instance
(Accurev) and build management system (Jenkins to manage and have a better view of build requests.
Skills:
