Embedded USB Debugger - S/W driver owner - Owned host PC side of EUD, a completely hardware-driven debugger-on-SOC. - Originated API library translating host PC Debugger protocols to EUD opcodes, extracting SOC coresight traces, and interacting with devices debugger logic. - Tasks: Originate OOD infrastructure (C++), test environment (Python), interface tools and release environment, coordinating deliverables across multiple teams and external corporations. JTag infrastructure owner - PoC for all JTag bring-up and debug activities - Created extensible framework for a turnkey debug interface on a continuously changing hardware platform (FPGA emulation of SOC's), using a limited language (PRACTICE) and code generation. A breakthrough at the company, this feature allowed developers to eliminate setup complications when developing code and accelerated the project's timeline for deliverables. - Overhaul of debug code to Object-Oriented style and automated testing of features. - Numerous device drivers, error handling and stack improvement - Oversee technical contributions from 3 engineers - Python, C, and Practice (Jtag scripting language)Audio Core Debug PoC - Chip bring-up owner for audio board support package on all chips. - Debug in low level C, assem, RTOS. - Responsible for ensuring delivery and troubleshooting challenging stability issues.

Brought a product from conception to install: managed new product's design, software development, assisted with hardware development, part sourcing and ordering, testing and QA with documentation, functional documentation, fabrication, installing a beta unit at a customer location, and integrating product production with company's logistics department. Product was a power electronics unit with safety critical functionality.Firmware Engineering for embedded circuits. Using resource limited platform (8051 chipset w/ 64k ROM, 2k RAM) Microchip PIC microcontrollers and MPLAB. Experience in an R&D lab development environment.Firmware Experience: Solid experience in C, low level and high level. Project involved more than 2000 lines of high and low level coding. Deployed RS232 communication between two microprocessors, overlaying a debug port on top of it.Hardware Experience: debugging power electronics for company's 30kWatt battery charging units. Comfort with electrical diagrams.
