WORK EXPERIENCE

Contract Software Engineer

Analogic - Peabody, MA - October 2012 to December 2013

Working with a software team to adapt existing software base to work with a new x-ray scanner. Responsibilities

included design and development of new features; extending old features; and general debugging. Worked

closely with electrical and mechanical engineers and physicists, to provide feedback, and support of our

software.

Skills: C++, perl, CAN interface protocol, lex, InstallAnywhere, Copley Motion libraries, wire-shark, TCP/IP.

boost libraries: any, format, circular, property tree, thread, variant, xpressive libraries.

Projects:

***Value Checker. Designed and implemented a domain specific language easy enough for physicist to use and

that allowed for arbitrarily complex expressions for testing various values from an (assumed) unreliable source.

Features included separating check variables to an xml file to be used in complex expression; when expression

fails against data values tested, the code flow is remembered and all variables leading up to failed expression

are printed and so are the expected values; verbose syntax checker makes it easy for non-technician to fix

their program. Used lex to translate domain language into C++.

***Installer. Wrote an installer for scan control software using InstallAnywhere. Wrote subsequent versions

in perl. Laid the framework for future extensions to the perl installer so that migrating, merging, checking

configuration data should be easier.

***Multi Keypad Feature. Extended keypad feature of the xray machine so that it could handle multiple keypads

instead of just one keypad. Primarily used C++, boost threads, and interfaced with CAN bus.

***General Maintenance/Extensions. Improved on and removed glitches to existing software. This included

finding and correcting sporadic race conditions, hanging shutdowns, memory leaks, cores, using wire shark to

debug unexpected closed connections. Also, modified Copley Motion code which is a third party library used

to control the gantry (xray ring.)

Contract Software Engineer

iRobot - Bedford, MA - September 2011 to October 2012

Responsible for designing and developing drivers for the new flagship iRobot product, RP-Vita. Worked directly

with mechanical engineers and electrical engineers to provide feedback on sensor design and also to provide

support (in the form of testing and developing test software) for trouble shooting electro/mechanical/acoustical

problems with sensors.

Skills: C++, Python, modbus serial interface protocol, aware2 robotics framework. boost libraries: any, format,

circular, property tree, thread, variant, xpressive libraries.

Projects:

***Sonar Drivers Development and Development Tools. Design, implemented, and tested sonar aware2 drivers

which gather acoustical data, convert raw readings from the sonar into range (object) hits. Sonars are the

primary source of clearing obstacles in the near-field of RP-Vita's localized space. Also, developed analysis

tools were to calibrate, and to trouble shoot acoustical, mechanical, and electrical problems.

***Pan motor driver. Design, implemented, and tested aware2 driver that actuates an electric motor which turn

RP-Vita's sensory suite 'head' and also queries the motor and position sensors to calculate the heading of the

sensor suite. Care was needed to synchronize the pan motor and sonar drivers through the modbus serial

interface in a timely manner because time stamping sensory data is critical in robotics.

***Baseboard driver. Design, implemented, and tested aware2 driver that queries the RP-Vita baseboard

hardware. The driver's tasks included gathering data from gyromometers and accelerometers and converting

them into physical quantities, sensing the RGB levels of the LED lights, and sensing the state of charge of the

RP-Vita's batteries. In addition to gathering data, the drivers then passed this data into the appropriate queues

and fielded commands from the behavioral system going to the various baseboard hardware components.

***RMT PrimeSensor (Kinect) driver. Design, and developed the PrimeSensor (e.g., Microsoft Kinect) driver

to detect when fixed obstacles have moved for the purpose of testing the reliability of the PrimeSensor and

custom made RP-Vita hardware.

Contract Software Engineer

product code to meet the needs of customers, and to train customers on the use of Axeda's products.

Skills: C, C++, Visual Studios, ASN1C, Training, Requirements Gathering and Functional Specifications.

Projects:

***Research and Development. Designed and developed Axeda wireless protocol library to fit on micro-

controller hardware of less than 4,000 bytes of RAM and using an 8-bit microprocessor. Tested to make sure

that library is bug free. System integrated new library with the hardware of one of Axeda's customers, All Traffic

Solutions.

***Medicis. Designed, developed, and tested a custom tailored solution for Medicis Pharmaceutical

Corporation, so that their Liposonix device could better communicate with Axeda base product. System

integrated solution with Liposonix device.

***Roche Pharmaceutical. Extended Axeda base product to meet the needs of various Roche Pharmaceutical

devices.

***Training and Requirements Gathering. Trained Axeda customers on the use of Axeda products. Went

on requirement gathering engagements to clarify the needs of customers. Some customers include Fujitsu

Skills: C#, C++, Perl, BizTalk Server, SQL Server

Projects:

***Scalability Tools. Designed and developed tools for creating, loading and timing extremely large volumes

of complex investment instruments and transactions according to client specifications. Wrote tools to measure

performance times of our software at various run stages. Mostly written in perl.

***Backup, Synchronization and Disaster Recovery Software. Designed software to support Geneva, an object

oriented database in the areas of backup, synchronization and disaster recovery. Prototyped in perl and finally

written in C++. Implemented software at various clients and trained clients on use.

***Portfolio Transaction History copying program. Designed and wrote perl/C++ software that would copy

portfolio transactions on specified security rules while preserving taxlots.
