DynaSoft LLC Contract - TravelPort (The data engine behind Orbitz/Travelocity/Priceline, and many airlines’ pricing solutions). In a software performance environment where milliseconds account for millions of revenue dollars, my talents and expertise have been vitally utilized in optimizing algorithms in a world-spanning data management application that handles >10 million transactions daily across >1000 production servers• Implementing sophisticated, multi-threaded design that reduced CPU idle time with results promising to shave 5-15 percent off of ticket pricing solution calculations (each 1% is equivalent to ~$100K savings).• Removed expensive, time-costly thread locking dependencies (posix thread mutex lock design) by implementing fast, atomic concurrency solutions which prove to be up to 30 times faster.• Implemented various efficient algorithms and techniques such as Adelson-Velskii & Landis (AVL) self-balancing trees, skip lists, hash tables, etc.• Implemented techniques that reduce tall-poles in dwell time such as NFS file caching• Increased data manipulation performance by utilizing memory mapping techniques, L2 cache techniques, data pattern layout/access schemes, etc.

This role required a high degree of time-constrained learning curve initiative for which I was routinely commended. I was “thrown into the deep end and was able to swim” for as many as three demanding programs during the first six-month tenure with Design_Net. All assignments were delivered with the highest standards and on short fuses, within time/budget constraints to the high degree of satisfaction of the customer.• Designed and developed “Collaboration Control” algorithms for PnP spacecraft on-board flight software components used for AFRL Defensive Counterspace initiative which allowed spacecraft to collaborate amongst themselves in order to accomplish mission objectives while under potential third-party threats without ground intervention. This component is one of 30+ distributed, multi-threaded software components in a suite that communicates over a variety of media through inter-process communications.• Designed and developed a robust fault-tolerant recovery system that optimally redistributes and rebalances processor critical applications when a failed processor is recognized.• Designed and implemented a user-friendly GUI interface to Design_Net Engineering’s Mission & Spacecraft Design ToolTM in JavaScript (Google toolbox) to web-enable the tool for end-users to reconfigure existing space assets for alternate mission objectives.

• Developed “Attitude and Articulation Prediction Simulation” software (~175K LOC) reusable simulation architecture used for Mars Reconnaissance Orbiter and Mars Phoenix Lander spacecraft. Modeled the kinematics and dynamics of multi-body articulating appendages resulting in the highly accurate forward prediction of spacecraft performance during mission phases when compared to flight observations.• Led a team of 5 individuals on a SBIR development to integrate hardware and software components into a real-time hardware-in-the-loop plug-and-play satellite research test bed. o This research program is intended to advance technologies that will lead to a six-day (mission requirements through launch and initial operating capabilities) turnaround spacecraft platform. o Effective management led to ahead of schedule milestone deliveries within a tight budget, and seamless integration with newly developed technologies corralled together from over a dozen partner companies.

Small business co-founder and 1/3 owner. IEC was dedicated to forwarding the distributed control system technology market amongst several disciplines.• Co-developed requirements for LONWORKS® technology Network Management Software Tools (Peak Components) • Developed and implemented Peak Components network Management algorithms that performed: o Node/router commissioning o Data binding o Diagnostics and maintenance

• Flight Telerobotic Servicer (FTS) program o Developed and implemented forward and reverse, real-time kinematic/dynamic articulation simulation (graphics FTS)/emulation (hardware FTS) of 7-DOF robotic arm including articulating end-effector and low-order joint dynamics effects. o Developed and implemented hand-controller reverse kinematic algorithms for human-in-the-loop position and rate control of the FTS. o Developed and implemented algorithms that resolved and fed-back sensed forces and torques at the FTS end-effector to the operator through the hand controller.• Magellan Venus Orbiter o Implemented 3-DOF (rotational) dynamic equations of motion incorporating flexible body modes of solar array dynamics which uncovered a catastrophic failure. This discovery led to a redesign of the solar array supporting structure.• Manned Maneuvering Unit o Responsible for all dynamic analysis and implementation in the Space Operations Simulation facility that led to three successful on-orbit, manned flights of the Manned Maneuvering Vehicle.  Initial test flight  Solar Maximum Satellite repair mission  Satellite rescue mission• Orbital Maneuvering Vehicle o Responsible for modeling several spacecraft control system configurations o Participated in human-in-the-loop simulation activities to ascertain:  Hand controller modes  Video processing requirements (frame rates, resolution, grey scale levels, etc.)
