Media Gateway development(2005-2009) Carrier Grade for Converged Media Gateway product. This feature provides protection against hardware failure by journaling data onto a redundant card.(2005) Team Leader in Carrier Grade Phase 1. The goal is to successfully journal a basic call and switchover (emulate hardware failure) and the call stays up.(2006) Technical support for Carrier Grade Phase 2. The goal in this phase to successfully journal all call types.(2007) Team Leader in Carrier Grade Phase 3. The goal is provide Hitless Software Migration (Calls stays up during software upgrade).(2004) Team Leader in the Lawful Intercept feature that provides law enforcement agency a way to tap calls without the knowledge of the clients.

Passport ATM (Asynchronous Transfer Mode) Networking, MPLS and IP development• (2003) Virtual Router (RFC2547): Responsible as a member of the team to deliver the IP Virtual Router functionality in the Passport environment. • (2002) Team leader in the AIS generation feature. A connection oriented signal that provides end-to-end notification when part of the optical link has been cut.• (2001) Team leader in Link Load Balancing feature. An algorithm that is able to intelligently select the least used path when routing a PNNI call. This was filed as a Patent by Nortel.• (2001) Request by management to move back in ATM Networking to provide team leadership and technical guru in PNNI algorithms. Spearheaded the PNNI Random Paths routing enhancement that reduced the routing calculations by 4000%. (In a complex network, the routing calculations was reduced from 40 sec to a few milliseconds. • (2000) Team leader in various MPLS features that provides interface support as well as routing enhancements.• (2000) Team leader in Double Booking Elimination feature: this feature enhances the Edge-based rerouting algorithm to eliminate double booking of link resources along the reroute path.• (1999) PNNI and H-PNNI implementation: Responsible as a member of the development team to deliver the Hierarchical PNNI feature for assorted Passport platforms. H-PNNI allows scalability of the PNNI network through advanced routing techniques and hierarchical grouping of PNNI nodes.

DMS (telephone switching) development• (1997-1998) Market liaison and release prime for ASEAN Market development in APC11. Development Prime for Legacy Captive Office Tutorial course. Design and implementation of International Services: Team leader CEPT Call Waiting (CWT) for Brazil (APC11), implemented Free Number Origination (FNO) for CALA (APC09.1), Malicious Call Identification (MCID) for Colombia (GL03.1). Support for GSF on Toll Break-In (TBI), Malicious Call Trace (MCT), Operator Request Hold (ORH) and Calling Line Identification (CLID) in GL04 (Delivered to China).• (1995-1996) Participated in the design of peripheral upgrade automation. The resulting system decreases the cost of switch upgrade through time reduction and decreased manual intervention in the software upgrade of peripherals.• (1993-1994) Architect in the Call Processing Server (CPS) Data Distribution System. Guided a 6 member team towards the initial release of functional analysis of CPS data distribution. Call Processing Server (CPS) is a distributed call processing engine which can increase the reliability and call processing power of existing telephone switches through parallel processing.• (1993-1994) Headed a 5 member taskforce to provide a highlevel analysis of CPS data distribution. Two of the team members are D-level managers.• (1992) Participated in the maintenance and enhancement of Integrated Node Maintenance(INM) and Integrated Link Maintenance (ILM). INM and ILM are two software systems responsible for the maintenance and recovery of peripherals and links between peripherals in a switch.• (1991) Participated in the development of S/DMS Distributed Software, removing the bottleneck from centralized call processing.• (1992-1994) Actively participated in the Continuous Improvement initiatives and promoted some of the CI programs by becoming a facilitator. The facilitator's role is to enhance the effectiveness of personal in a team environment.
