As a software engineer, a small team and I were responsible for creating, deploying, and supporting a suite of custom spring boot micro-services that handled data flow for autonomous capable vehicles. This data was used for the system learning and model training.In addition to the software suite, we also created our own automation and test tools using a combination of Python and Bash. One such example is a message generator tool that we created to test how a micro-service would handle multiple messages on multiple threads at the same time.• Helped to design and create a spring boot micro service that received and stitched together data used for autonomous driving system learning. This micro service made use of Oracle SQL, Redis, Amazon S3, and Kafka Messaging.• Helped to create a spring web micro service that acted as a gateway for file uploads from autonomous capable vehicles. This micro service made use of Oracle SQL, Amazon S3, and Kafka Messaging. This micro-service acted as a REST endpoint, taking requests and sending replies back in JSON format.• Helped to design and create a spring boot micro service that used two-way communication with vehicles to upload large files used for autonomous driving system learning. This micro service made use of Oracle SQL, Redis, and Kafka Messaging.• I was recognized internally as part of GM's Engineering Week for my work on the above mentioned file-stitching micro service.

• Designed, created, and deployed a single pane of glass dashboard for our DDoS mitigation service customers. The application used JWT tokens as part of its rigorous authentication process. Additionally, it interacted with an ELK (Elasticsearch, Logstash, Kibana) cluster to pull data about how the service was working for them. A modern mobile-first UI and interactive graphs displayed the customer's data, and they also could print and download these reports as PDF files.• Designed, created, deployed, and supported a mobile-first web application that could store our partner carriers' serviceable addresses. The program could import Excel files ranging from 5 MB to 250+ MB in size. I wrote the file import module in C to ensure the fastest processing of files. The addresses were stored and sorted by partner carrier in a central database and then made searchable via a PHP (later updated to NodeJS) back-end.• Currently working on a mobile-first web application that will keep track of the company’s inventory, and allow for different reports to be generated that will visualize the trends of inventory intake and output. Additionally, the program has built-in user access controls, IP address filtering, and various administration tools and options.
