Provide POC web-site to replace legacy in-house admin web sites to configure customer cable systemsDesign and Development of a network automation tool which requests and retrieves diagnostic data of cable set-top boxes using asyncoro Python asynchronous sockets library. Supporting 1024 simultaneous socket connections, this version queries 250,000 clients within approximately 5 minutes, utilizing generator based network connections to avoid the Python Global Interface Lock.Developed a simple Python package to support thousands of simultaneous send and receive SSH requests to multiple remote computers utilizing parallel processing.

Design and develop Equity Risk Correlation reports written in Python, developed in the BOA Quartz environment. Utilize the BOA grid computing software and hardware which provides the ability to execute Python code sequences on tens of thousands of x86 cores located at data centers in geographically diverse sites. This supports highly parallel calculation of grid enabled algorithms, as well as the ability to quickly test and debug local calculations with low latency on a local PC.Development of Equity correlation regression analysis suites to insure that newly developed correlation engines and changes to the correlation algorithms could easily be compared to previously designed and developed algorithms to insure the ability to test data and to compare initial correlation calculations with newly developed algorithms. Development of specialized unit tests to insure that all test cases have been coveredUtilize proprietary BOA Sandra database

Design and develop Automated Test Software (ATS) a distributed test platform written in Python. The ATS suite is used to verify and validate RESTful APIs which control a high-performance content delivery system. The ATS was developed under Windows 7 and Linux using XML to configure all potential API calls. Linux RPC clients were developed for the Linux Content Delivery elements to verify system performance. Tests utilize Remote Procedure Calls, IPTABLES, NFQUEUE, Postgresql, MSSQL, and Linux system calls to independently verify and validate the API.. Actively discovered dozens of bugs, determined system lock, multi-thread and performance issues. Skills – Python, Linux, TCP/IP, Windows, RPC, REST APIs, Test Software, JSON, XML, MSSQL, Postgresql.

Managed, developed and maintained an Avionics Test Lab, responsible for full life-cycle product design of Automated Test Equipment for the Fuel Quantity and Management System (FQMS), the fuel gauging and control system for the Airbus A380 and A350 Aircrafts.

Responsible for full life-cycle engineering services for the Reuters Color Graphic Terminal and the US Dollar Index projects. Initially developed as a prototype product, the Reuters Color Graphic Terminal was the initial financial services product from Reuters providing analytics for real-time financial data that is transmitted over the Reuters Small Dish Service (SDS). The US Dollar Index project provided FINEX with the index by calculating the relative strength of the U.S. Dollar versus 10 currencies. The index continues to be calculated, now using the Euro, Japanese Yen, British Pound, Canadian Dollar, Swedish Krona and Swiss Franc.
