Lead contributing engineer for a small internal consulting group. The group designed and implemented firmware and hardware solutions for products that require standardized embedded network interfaces and protocols. Responsibilities: embedded hardware and firmware design, writing ‘C’ code to support system monitoring; design and implementation of all user interfaces (graphical, textual and network various protocols). Main focus on products used to provide Network Critical Physical Infrastructure (NCPI). These products offers APC’s full network support suite; including: HTML, Telnet and SNMP interfaces; local display user interface; alarm and event notification via email.◊ Responsible for the electrical and firmware design and implementation of a 3-phase power monitoring system. This multi-processor system is used to monitor the power supplying critical datacenter equipment. Features of the design included: sampling of multiple 3-phase voltage and current waveforms; RMS voltage/current and real/apparent power measurements; alarms generation based on electrical measurements; embedded web-server for remote access; Telnet & SNMP access; event and data logging; alarm reporting via email and SNMP. Network management and user interfaces coded in ‘C’ in a real-time environment. The power measurement system was coded in mixed assembly and ‘C’.◊ Designed and implemented the monitoring and control for standardized 125 and 200 kW standby power generation systems, used to support NCPI applications. Systems included automatic transfer switches (ATS) up to 800 amps, based on motorized circuit breakers. Sample level monitoring of input voltages allows the ATS to be switched so that power interruption to the load was minimized. Responsible for firmware and electrical control design and implementation.◊ Designed the monitoring and control for a rack air-removal system, used to cool the next generation of high-density blades servers.

Managed a start-up venture responsible for developing new products and strategies for powering the evolving telecommunications infrastructure. This group supplied battery-backed DC power supplies for use in the emerging cable telephony, and fiber-to-the-home market.◊ Led a small and rapidly growing entrepreneurial business unit, in a large corporate setting.◊ Managed and participated in the design of cost-sensitive power supply products for volume manufacturing.

Staff Firmware Engineer / Program Manager:Responsible for program schedule, staffing, and offering technical leadership and guidance to the design team.◊ Lead a team of 6 in the development and release of a 5kva rack-efficient UPS designed to meet the increasing power demands of newer multi-processor servers and RAID systems.◊ Managed a cross-functional team of 12 design engineers and technicians in the rapid prototyping of a fault-tolerant, rack-mount UPS system, specifically aimed at high-availability applications.Senior Electrical/Firmware Design Engineer:Responsibilities included the design of new micro-controller based products. Overseeing all aspects of product development cycle including: Product definition, prototype development, hardware and firmware design, and release to manufacturing.◊ Major contributor in the development of a fault-tolerant UPS system offering hot swappable, redundant modules. Developed, and implemented routines for monitoring of the system and electrical parameters, self diagnosis, fault and alarm reporting, and serial communications with the operating system. The RTXC real-time kernel was applied, with coding done in ‘C’. The product’s hardware architecture utilizes multiple 8051 and PIC micro-controllers, with inter-module communications via I2C.◊ Worked as part of a team of 4 engineers that developed APC’s MasterSwitch product. APC’s first web-based product, it employed an embedded web-server, and allowed the user to remotely control electrical outlets using a web-browser.◊ Implemented a standard architecture using the Intel 8051 family, which facilitated rapid development of the SmartSlot line of accessories used with APC’s UPS products. Functionality provided by these accessories includes: remote (modem) terminal interfaces, UPS monitoring port expansion, environmental monitoring, contact inputs/outputs, event logging and paging.
