Designed and Implemented our Data Processing Pipeline Infrastructure, creating fault tolerant structures to automate much of our consumption and processing to reduce our end to end processing time from 10 days to 4 days- Process petabytes of data across many different external, partner, and in-house datasets to produce a single dataset to be published to online store, using SQL/MapReduce-like scripting to process data in Azure Data Lake Storage- Creation of several pipelines in Azure Data Factory, with automatic triggering to reduce downtimes while balancing across limited computing cluster to avoid overworking. Designed common frameworks with rapid development in mind, creating configuration based pipelines and unit testing frameworks in C#- Created services to process upstream data, with fault tolerant mechanisms and efficient caching, bringing down runtimes from days to hours

Model finders such as SAT-solvers that are used for optimization purposes often give arbitrary and often misleading models. Our study aimed to find the effect of minimal, maximal, and arbitrary models on the students' interpretation.- Using SQL databases, filtered through thousands of models to determine the effectiveness of minimal and maximal models- Constructed software that could run arbitrary first order logic predicates on a set of models, keeping in mind any changes for future studies, allowing for extensibility for users and researchers in the future- Using regex, handled noisy data to allow for efficient data comprehension

- Redesigned assignment, making sure that concepts and lessons were communicated effectively to all students- Reinforced and taught concepts to students, both in groups and one on one. - Presented feedback to both the course staff and students on performance, giving concrete areas of measurable improvement.

An assistive device for the blind. By combining a neural network that can perform real time object detection and playing sounds in 3D space, we can give a user immediate feedback about their surroundings.- Redesigned the structure of the project to be modularized and distributive, using protobuf and ZeroMQ- Designed the central architecture to allow communication between hand tracking software and acceleration data

Brought Computer Science to all levels of education, bringing in pedagogical tools of Computer Science and incorporating them into Algebra, Physics, and other courses.- Created programs for data analysis and collection in R and Google Apps Script, conclusively showing performance improvements that were published in the paper: Assessing Bootstrap:Algebra Students on Scaffolded and Unscaffolded Word Problems- Researched and presented different pedagogical tools to maximize student's understanding of Computer Science and mathematical concepts in our new data science course.
