Develop 3D print preparation software for the machines SpaceX uses to create their rocket engines by using my knowledge of Qt, OpenGL, VTK, TBB, debugging techniques, and other skills to build custom features, perform troubleshooting, and create performance improvements that solved several long-standing issues which were severely impacting usability, reliability, and performance of the product

Waltham, Ma, Us

Senior Software Consultant in a consulting company. Involved in many aspects of the business including bid estimation, training development, marketing, but mostly writing world class software for an ever increasing variety of happy clients.Developed unique embedded-device startup code in C++, Qt, QML, JavaScript, and QNX allowing a complex medical application load in less than 4 seconds from device boot that solved a critical marketing requirement for Zoll Medical. Received a financial award and special recognition for this work.Developed unique integration of Qt QML and VTK allowing the creation of modern, performant, declarative cross-platform desktop applications using VTK pipeline processing for BlueQuartz Software.Added 2-pass Order-Independent Transparency algorithm to Abbott’s cardiac ablation device. Improved rendering performance 8x.Created cross-platform desktop application to integrate and display imaging data from x-ray, ultrasonic, and color-image sensors. Developed optimized image display algorithms to allow real-time performant user interface experience while manipulating several hundred mega-byte images.Created OpenGL based real-time rendering 2D chart component for a new embedded medical diagnostic device. Added software rasterization to a real-time graphing library to handle data visualization and user input for a new ventilator/respirator embedded device for Hamilton Medical.Created OpenGL graphics for an embedded agricultural GPS device for TeeJet Technologies. Improved render performance 12x from 5hz to 60hz.Created a CPU performance benchmark in C++, OpenGL, and Oculus for Intel highlighting the differences between i5 Core and i7 Core processors in Graphical and Virtual Reality fields. Authored a companion paper to this work that was published on Intel’s Developer Zone to help other developers understand best practices when working in Graphics or VR.

Developed a data visualization application in C++, Qt, OpenGL and ROS to be used in developing autonomous vehicle control software for PhantomAI.Developed the mapping layer of an embedded Qt/QML application using OsgEarth, OpenSceneGraph, and OpenGL. This required deep understanding of each technology and custom modifications of OsgEarth to work with GLES 2.0 in the embedded device.In-house instructor for ICS’s 5-day OpenGL training course. Extended course to add missing material and corrected code samples for class.Developed five-part blog series describing best practices for migrating legacy OpenGL applications to ModernGL using Qt. Presented one-hour webinar on first blog post to 100+ listeners.Developed an OpenGL based real-time graphing library to handle data visualization and user input for a new ventilator/respirator medical device for Hamiton Medical. Created the rendering code in C++ using OpenGL, implemented the C++ and QML interface to the graphing code, and wrote API and design documentation in accordance with requirements for medical devices. Developed a C#/WPF (XAML) application and corresponding article for Intel’s Developer Zone demonstrating best practices for working with various features of the RealSense 3D camera. It uniquely combined working samples along with instructional technical documentation and code examples in a seamless application.Created a Universal Windows 10 (XAML) application running on desktop, tablets, and phones that delivered a secure e-mail client for a large fortune 500 company. It was developed in C# against UWP API and used Cortana, REST APIs, dynamic layout, and other technologies.Troubleshot, diagnosed, and worked around several embedded OpenGL driver bugs which were preventing GE Oil and Gas from delivering a new product. Optimized their performance critical code resulting in 8x speed improvement. Diagnosed a random OpenGL “glitch” that was preventing a medical company from delivering a new product

Expanded an existing OpenGL graphics rendering engine for big data visualization based in OpenSceneGraph to add the “graphics sizzle” needed to bring the product to top-level readiness for software sales. At request of management, recreated the rendering engine for current and future compatibility with latest-gen shader-based rendering devices such as tablet, phone, WebGL, and enterprise virtualization. Ported this new rendering engine to be compatible with ANGLE and then created a custom WPF control and associated .NET interop assemblies to create a new SDK compatible with WPF. Converting a large existing C++ application to be compatible with .NET/WPF technologies.

Austin, Tx, Us

Managed all aspects of two virtual reality laboratories to create an environment that provides consistent, correct, and continuous production of scientific data across many different systems and for many disparate users. This required acting in many roles including Project Manager, Operations Manager, Research Scientist, Software Engineer, IT/Network Design & Administration, Hardware Engineer, Procurement Officer, and Public Relations.Created complex custom software and hardware which integrates a diverse mix of esoteric components into systems that produce seamless, real-time, and immersive virtual reality environments.Engineered or identified, evaluated and procured virtual reality and general purpose hardware for use in the lab such as virtual reality helmets, custom eye trackers, 6-dof position sensors, force-feedback robotic arms, emg sensor systems, and a 6-dof hydraulic platform.Managed, supported and/or interfaced with a wide variety of personal in the lab such as graduate students, post-doctoral fellows, visiting scholars, VIP guests (including Aneesh Chopra), and the general public.

Rochester, Ny, Us

Software/Hardware consultant for a group of 30+ research faculty. Provided expert engineering analysis and design to create experimental systems for scientific research.Created a complete system for the collection and analysis of neural data obtained from awake-behaving monkeys. The system allowed for accelerated experimental design maximizing science data available for research. Data collected using this system led to a scientific paper subsequently published on the cover of Nature magazine.Built an embedded controller from disparate components to control a 96 channel deformable mirror. It was the key component in system that allowed for the first-ever direct observation of living rods and cones in a human eye.Wrote custom software to analyze Optical Coherent Tomography data used to measure several aspects of the physiology of human and animal eyes. Data from this system is used in developing advanced Lasik corrective surgery procedures and equipment.Designed and created an infant audio/visual stimulation and recording system. Data from this system is used to understand how learning occurs in the human mind.Wrote a custom software package to provide real-time control over laser based visual acuity experiment. Data from this system is used to understand how the human visual cortex processes signals from the retina.

Taught an “Introduction to Computer Programming” class. This was a ‘gateway’ class that students of all majors were required to take. It consisted of lecture sessions of over 200 students plus a hands-on lab component in which I was required to provide individual assistance. Achieved student feedback ratings comparable to other experienced/tenured professors.
