Projects I am proud of are…
Williams Communications
Group, WilTel , Level 3 Communications.
· Senior
Software Architect for a geographic diverse development group that is
delivering an application responsible for routing videos feeds for news and
sports content across Level 3 lP network for major broadcasters. This application was the primary way Vyvx received video
reservations. 70% of video reservations where online within 30 minutes of Vyvx
receiving the video reservation. Written in C++ using gcc, on Solaris/Linux.
· Senior
Software Architect on internal web application for our Telco Pricing
application written in C#, html, java
script. The application was architected to make application scalable with
better integration with our CRM application (Siebel) using direct api calls
into Siebel as well as using data from Siebel database and web services to
obtain data from a teleco vendor and mapping software and object oriented in order to make application more flexible for future
growth and change. Pricing application was viewed by sales and marketing management
as a competitive advantage for Level 3 against it competitors by allowing sales
force to quickly and confidently deliver quotes using a step by step approach
and allows marketing to track leads and sales by market, product, etc. Technologies used were C#, ASPX, Java script,
Oracle, MapInfo MapXtreme and Siebel.
· As the software architect I lead the
analysis, design, and development for IP network Service Level Management
(SLM). I was team lead/Architect responsible for collecting measurements on the
IP network. Measurements include Network availability, Packet loss, Latency,
Jitter. Level 3’s SLM application was a sales differentiator for sales and operations by allowing customers to see entire SLM from end
point to end point. We are able to measure network core, edge to core, and end
to end. Code written in C++ using gcc, on Solaris/Linux. Uses Pthreads, LIBPCAP for Real-time C++ Network Systems Programming. SLM has a
front end web portal written in Java, JSP using JBoss. Oracle is the database
on a Sun Solaris server.
· As the software architect I lead the development of the usage and discounting modules for a wholesale
voice telecommunications billing system. WilTel discounting was heavy used by
sales to implement various discounting models to help create sales. Application
was design so sales could create discounting models without having to ask IT
for enhancements to existing application. Voice Billing was a large revenue
source. The model was developed using C++, MS SQL, Windows NT.
· Was a team member looking at integrated solution
for single sign on solution, Also part of security team acting as a liaison
between Development and Infrastructure within IT.
BellSouth Wireless.
As a Lead Developer/Technical Manager design,
develop and implement a cellular billing system. Special attention was paid to
object orientation, scalability, flexibility and above all efficiency. When I
left BellSouth we processed 156 bill cycles per month for over 1 million
customers. Average bill cycle had between 30,000 to 50,000 customers. This
application also reduces cost per bill from 3.00 per bill to less than two
dollars per bill
· Personal responsibilities included Call processing module, reporting module
and the post-billing module. Later became lead developer/technical manager of
the team with responsibilities, which included management of ongoing
development, analysis and design of new requirements, and production
implementation. System was written in C++ on AIX UNIX utilizing Sybase
database, DCE interprocess communication. Application was able to process 158
bill cycles per month. Each bill cycle has an average of 20,000 to 35,000
subscribers.
· Wrote data transformation system using C++ and Sybase SQL and stored
procedures. System accepted real time feed of changes from an AS/400 database
via SNA LU62 and translated the information into a Sybase 10 database.
· Wrote a TCP interface using C++ and RPG from an AS/400 to an AIX UNIX
system to provide interprocess communication between Customer Care application
and Cellular switches.
