JOURNEY TELECOM, LLC, remote 7/09 – 6/10

Co-Founder

Velocity is a real-time transaction processing engine designed for high throughput transaction processing. Written in C++ for both Windows, Solaris and Linux, Velocity can easily be extended to implement the most complicated transaction processing needs. The target throughput for a complex transaction was between 5,000 and 10,000 TPS. Transaction volumes exceeding 100,000 TPS have been achieved with a simple transaction in a test environment. Velocity is currently in use by a telecommunications carrier as the foundation for a call routing application.

Foundation Tools is a cross-platform C++ library for developing multi-threaded applications on Windows, Linux and Solaris platforms. This framework was developed to support Velocity. The threading framework is based on an event processing model. Components include threads, timers, shared memory based queues, custom semaphores, logging and socket communications.

The Performance Monitoring module collects and analyzes call detail records in near real time. This information provides the operations team with a real time view of the quality of service being provided by the underlying vendors.

Responsible for billing operations and all software development to support the billing process.

Billing Operations

Managed the rate quoting and billing processes for approximately 80 wholesale customers who generated in excess of billion minutes each month (160 million CDR’s and more than $3 million in revenue).

Performed detailed analysis for customer disputes (on average, one per month). The automation of the rate quoting and invoicing processing greatly reduced customer disputes.

Automated the invoicing process. This was a manual process that took approximately six hours six times a month and 10 hours once a month. The resulting process took less than 5 minutes per cycle.

Automated the generation of customer rate sheets as well as the loading of the rates into the billing system. Previously this process was manual and would take 3-4 days to complete each time new rates were sent out (once a month at a minimum).

Successfully migrated from an external hosted billing system to an internally developed billing system. The implementation of this system resulted in an ongoing annual savings of over $330,000 with no incremental staff.

Managed the vendor invoice and CDR reconciliation processing. The implementation of CDR level invoice reconciliation yielded over $150,000 in savings in the first six months of operation.

Software Development

Designed and developed an automated, near real-time CDR collection and distribution system. This system was written using C# and Perl and utilizes both FTP and TCPIP.

Designed and developed a CDR mediation and rating platform capable of processing over 30 million raw CDR’s daily. Typically, CDR’s are rated and available in the billing system in less than 2 minutes from the time a call is completed. This system was written using C++, C# and TSQL.

Designed and developed a wholesale billing system capable of billing over 700 million CDR’s monthly. In addition to customer billing, extensive reporting and analysis tools were developed for vendor cost management and customer margin management. This system was written using ASP.NET, C# and TSQL.

Designed and developed a CDR level vendor invoice reconciliation system. This system matches internal CDR’s to vendor CDR’s. The resulting data is then used for various types of analysis including vendor rating verification and minutes verification. The system provides detailed data to support disputes filed with vendors. At present, the system processes CDR’s from 15 different vendors.

Designed an LNP system used to support both call processing and back office functions. This included the collection and processing of data from the NPAC regions and storage of the historical data for use to verify vendor invoicing as well as a highly available system used for call processing.

Principal Engineer 2/00 – 6/02

Responsible for the design, development and implementation of various business technologies.

IVAN – Intelligent Validation Network – This product brought in house the call validation process resulting in a savings of more that $150,000 per month. Performed all analysis, design, development and testing. The platform currently processes approximately 750,000 validation transactions per day. In test mode, the platform was able to process over 10,000 transactions per minute (no LIDB lookups required). The average in house processing time, excluding transport and LIDB, is 40ms/transaction. A key feature of the platform is the highly redundant scalable distributed architecture which guarantees system availability. The platform supports various transaction transport methods including TCP/IP, X.25 (Eicon) and DTMF (NMS). The platform runs on Windows NT and utilizes MS SQL Server. The object oriented system was developed using C++. Inter-application communication is implemented using TPC/IP and shared memory. Neighborhood data synchronization utilizes MS Message Queues. Application health and alerts are reported via SNMP.

CAMRM – CAM Recording & Monitoring – CAMRM provides call recording and monitoring for analog telephone systems which do not support these functions. The system utilizes the Brooktrout Realblock board with Analog Passive Tap modules. Calls can be live monitored via Microsoft’s Internet Explorer.

The system was developed using C++ and utilizes the existing CAM data model. The system was developed from scratch and initial development (fully functional) was completed in 2 weeks.

TP – Telephony Processor – The intent of this system was to allow higher level programmers to develop robust telephony applications. The system utilizes the Microsoft Active Scripting Engine, COM technologies, and Brooktrout’s Realcomm telephony engine. Designed and developed a COM interface to the Realcomm engine which encapsulates the necessary functionality for call processing (dialing, DTMF collection, message prompts, call acceptance, call bridging, etc.). The system allows developers to write telephony applications using VBScript or Jscript.
