> Redesigned the autonomous vehicle evaluator.---- Rewrote large portions of the code base, implementing proper design practices and improving code readability and maintainability.---- Produced sequence diagram detailing the updated control flow of the evaluator application.> Designed the data metamodel used by the autonomous vehicle stack's new safety monitoring system.---- The events-based design standardizes how data of any form enters the safety monitoring system and how it may be subsequently transformed.> Improved testing of the autonomous vehicle evaluator; added unit tests for non-metric components and created MVP for coverage testing the project code base.> Developed preplanned metrics for evaluating the driving performance of autonomous vehicles.> Mentored other co-op students in Git and in Python.Language: PythonWorkflow Technologies: Git, Anaconda, pytest + flake8, Gitlab CI, Docker + Kubernetes, GNU MakeProject Technologies: gRPC, ROS, docker-py

> Rapidly acquired an understanding of the existing literature on group-labellings of biased graphs.> Redesigned a computation experiment investigating cycle structures within biased graphs. Original program ran for over four days; rewritten program yielded desired results in under an hour.Department: Combinatorics & Optimisation

> Designed and implemented a RESTful microservice that handles resource access and configuration management for other microservices on the Omni-Channel Platform.---- Employed multi-level caching and parallel computing in the microservice implementation, yielding a throughput of thousands of serviced resource requests per second on a developer machine.> Developed accompanying client library for seamless retrieval of resources by other microservices.> Produced entity-relationship diagram visualising the data model of the Authentic Payment Platform while familiarizing myself with the code base.> Oversaw initial testing for new microservice during team experiment with test-driven development.Omni-Channel Platform: https://www.ncr.com/retail/food-drug-mass-merchandise/omni-channel-platformAuthentic Payment Platform: https://www.ncr.com/financial-services/payments-transaction-processing/authenticLanguage: JavaWorkflow Technologies: Git, Maven, JUnit + Cucumber, Jenkins, Docker + Kubernetes, JIRAProject Technologies: Spring Framework, Apache ActiveMQ, Apache Cassandra
