Lead cloud media services design and development for Amazon Cloud Cam. Developed cloud services for managing WebRTC SFU processes & computer vision pipelines, worked on GStreamer media pipelines for computer-vision driven clip creation, scaled the system from hundreds to hundreds of thousands of concurrent cameras.Worked with senior engineers from Ring and.

Acquired by Amazon Lab126.Optimized texture mapping (bilinear interpolation to dewarp fisheye camera images) in C and assembly for a high performance, low powered embedded SoC (Movidius).Worked to understand the architecture of the SoC and designed strategies to organize data structures according to the capabilities of the chip to drastically reduce.

Attempted to parallelize GenSel, software that analyzes data to predict which genes affect specific phenotypes. Algorithms involved Markov Chains using Monte Carlo methods (Gibbs sampling). Software originally used the Eigen C++ library.Parallelized the matrix and vector math involved using CUDA to interface with Eigen; main algorithms involved were SAXPY.

Atascadero, California, US

Designed web components using a Java DSL (Domain Specific Language) to represent HTML and Javascript as Java Objects. Java was also used for the server, back-end logic, and in a custom Model-View framework to organize the code.I often worked with Javascript, jQuery, and asynchronous logic in designing components for the web site, and also worked with.

St. Paul, Minnesota, US

Designed a program that collated statistics from test results/timing benchmarks which were in various formats (HTML, CSV, XML) and exported the results to generated static HTML pages. That way results could be stored on internal shared file systems instead of spinning up servers to query results.Worked with Java code base to fix bugs.Designed tests with.

My main project was developing a system where Residential Advisors (RAs) could check out equipment and be automatically notified when their equipment was due back.
