Provided software development support for the Ambient Broadband over Power Line (BPL) and trial deployment at Duke Energy.• Designed and implemented BPL modem firmware build environment to incorporate Ambient specific code. • Designed and implemented the communication interface between Linux host routing software and the BPL (DS2/Marvel) network processor as well as the BPL modem initialization sequence.• Designed and implemented the BPL firmware VLAN to port mapping interface and port management between the Ambient Linux host platform and the DS2 power line modem.Provided software development support for the Ambient integrated power supply board. Specific contributions include:• Made major enhancements to control the regulated power supply control during initial device boot sequence.• Designed and implemented boot fail-safe, boot stage indication, AC loss detection and reporting, backup power type detection and charging algorithm. • Converted and enhanced the initial PIC 18F25K20 software design written in assembler to a PIC 18F46K20 in C. Provided software development support for several Ambient embedded Linux smart grid models. Over 130,000 Smart Grid models have been deployed in the Duke Energy grid. Specific contributions include:• Designed and implemented Linux device driver modules for Analog Devices ADE7758 and 7880 energy metering chips. • Designed and implemented a Linux driver module to interface with the integrated power supply board via I2C. This driver is used to report intelligent power supply board status, configure its parameters and report AC loss and node intrusion interrupts.• Designed and implemented Linux host applications, api libraries, utilities and daemon processes for power quality measurement and intelligent power supply board configuration and monitoring. • Designed and implemented Ambient’s first SQLite feature configuration database and supporting utilities.

Implemented the General Packet Radio Service (GPRS) on SavaJe’s Java centric mobile (GSM) operating system. Specific accomplishments include:• Implemented in Java a managed GPRS network subsystem that coordinates communication and connectivity between one or more GPRS network interfaces and the GSM network.• Redesigned the SavaJe core GPRS subsystem to support TI’s packet oriented GSM stack. • Implemented a GSM modem that provides Internet access for PC’s connected via USB, Bluetooth or IrDA.

Provide software support on the 3Com stackable Remote Access Server 1500. This project was completed and delivered on time.SW Development responsibilities and contributions in the following areas:• Designed and developed the multi-channel interface between the 3Com RAS 1500 and 3Com High Density Modem T1/E1 PRI unit. • Design, integrate and debug portions of IP Routing, call initiation, call on-demand, NAT, DHCP, and system areas such as buffer management and inter-processor communication.Provided software support for the 3Com DSL Office Connect Gateway. This device achieved “five 9’s” reliability and multi-vendor certification. SW Development responsibilities and contributions in the following areas:• Led a software team to develop and implement Voice over DSL using proprietary and standards channel associated signaling. Personally responsible for Voice over ATM standard implementation. • Led SW performance and optimization team to achieve DSL converged voice/data and Voice Gateway certification.

Marlborough, Ma

Provided software support for the GDC Apex ATM switch. Software Development responsibilities and contributions in the following areas:• Designed and developed task code for Ethernet to ATM adaptation controller, ATM layer, Ethernet broadcast interfaces, and buffer management. Controller supported multi-processor Motorola 68060, Fujitsu ATM controller and embedded OS.• Developed a single PNNI node in GDC’s distributed signaling environment and integrated ATM Forum standard PNNI with GDC’s existing proprietary APEX ADTL routing mechanism.
