Primarily server side development for an embedded Android media streaming product.○ Created a Virtual Input service using the Linux kernel uinput module. The core of the service is a C++ class that implements a virtual keyboard and a virtual pointer device. The service instantiates a secure WebSocket server (Kotlin/Java) allowing clients to send messages that are mapped to actual keyboard and mouse events. Modifiedthe Android OS build to resolve SELinux and pointer motion issues. REST API configures and controls the service.○ Lead the efforts to implement digital signage as a micro-service. Back-end is written in C++ and front-end in Kotlin.Designed the IPC interface between the main application and this new service. Updated build scripts to handlethis new application artifact and properly deploy it.○ Performed an SOC evaluation for next-gen product running a yocto Linux. Configured, built, and ran the OS, and then bench-marked video encode/decode performance.○ Made improvements to WebRTC and API servers, both implemented in rust.○ Helped write a C++ memory logging utility for detecting leaks and wasteful heap usage. Made improvements to the CMake build system. Features and bug fixes covering many areas, including: GL Math Library usage, QA python tools for log parsing, and client side improvements in Qt/QML.

Key contributor on a team developing a message passing framework within an event-driven architecture. Messages between nodes are serialized/deserialized using Flatbuffers in C++ and Java implementations. The network nodes run on android and microcontroller devices, as well as on desktop platforms. My work is focused on the intra-node development for ECUs, GNS receivers, and Android display.Created a new git repo to build and publish an internal software product. Native components build via CMake for Mac, Linux, Win and RTOS platforms, and are published as conan artifacts. Java components build via gradle and are published as Maven artifacts. Common data types are defined as Flatbuffers schema and compiled to their respective C++ and Java versions as part of the build.

Adding new features and optimizing existing ones for Sensory’s TrulySecure (TS) face and voice biometric SDK. This is a multi-platform OOD product, core is in C++ while the public API has Java, python, and Objective-C language bindings. My work covers our full software stack – from data acquisition to the presentation layer.Some accomplishments:○ In recent releases: added standalone liveness mode, made improvements to base liveness capabilities, added“Self-Consistent” biometrics to block spoof attacks.○ Designed, developed, and implemented a point-cloud processing library used as a submodule by the main SDKbut also as a standalone module callable from python, Matlab, or at the command line.○ Starting with research code (Matlab) implemented new data processing components: - 3D face authentication from time-of-flight (3D) camera - 3D pose estimation from 2D imagery (Perspective-n-Point algorithm)○ Made a major contribution to the refactor of our build system (combines gradle, CMake, maven, and SWIG).

Developing software solutions for challenges in solar forecasting and space environment modeling.Developed an algorithm in Python to determine solar terrain shadowing based on latest NASA digital elevation data. Setup and administering a cloud based Postgres/postgis database aggregating satellite atmospheric data from several different NASA sources, writing client code in Python. Wrote an Android application to display household energy usage.Led the software development of new product, written in C++, to convert common CAD file formats to those used in scientific applications. This includes creating new visitor classes that are part of an existing visitor design pattern implementation.

Developed and implemented a method to embed Java analytics within a database server, eliminating bottlenecks when doing analysis on clients. Improved software development times for prototype to production by a developing a method to easily call Java numerical libraries from R and Matlab environments. Wrote white papers and presented webinars in support of this work.

Broadly, I am working on theoretical condensed matter projects primarily focused on novel structures and materials for solar energy conversion.The particular systems include iron pyrite nanocubes, carbon nanotubes, and nanorod heterojunctions. Among the computational techniques I use are density functional theory (DFT) and the discrete dipole approximation (DDA). I employ various analytic tools from condensed matter field theory including bosonization, the renormalization-group, and the Hubbard model.Currently I am principal investigator (PI) for the computational portion of a research project investigating the properties of iron pyrite nanocubes. In this role I manage the research group's usage of the supercomputer Stampede at TACC (part of NSF's XSEDE).In addition I mentor graduate students in the research group.
