Developed an internal website that tracks networking services and provides tooling and automation to debug. Established builds, releases, and CI/CD pipelines on Azure DevOps for multiple team services and the ground-up that was security compliant and deployed software that followed safe deployment procedures.

• Created ARM templates and custom extensions to automate the infrastructure of multiple services, and modified existing templates and scripts for region buildout discrepancies
• Produced design document reviews for the team and provided improvements to existing architectures
• Utilized OAuth to provide Authorization and Authentication to allow certain users in the Active Directory to allow access to the website and perform API calls

Developed a service that replicates data into all regions, allowing customers to perform API calls to fetch up-to-date data, and overcome limitations of restricted regions. Created workflows that would move data from data sources to S3, DynamoDB to an API, and stood up dev environments to validate the workflows. Launched an internal ticketing service in multiple regions, that would allow internal teams to perform ticket automation and workflows on their tickets, using it for my own team’s automation.

• Established CDK and pipelines for infrastructure as code automation and debugged a variety of software, certificate, and missing data issues.
• Provided cross-team collaboration to identify differences in regions, including how to resolve missing dependencies on services that are not available.

Developed an in-house testing application that simulated end-to-end testing on a distributed system consisting of over a thousand test cases to identify if any code changes regressed from the baseline runs. Dockerized the application, and utilized Kubernetes to manage the cluster and to separate resources from dev and prod
environments, along with spinning up Pods to run the tests on demand

• Migrated services to the cloud and architecture redesign such as SQL database to NoSQL to better match the data model and created evolver classes to transition
• Performed JVM optimizations and improvements to existing algorithms and comparisons.
• Mentored and assigned tasks to two other developers, along with managing the requirements and software releases

Developed parsers for several file formats that processed data contents and extracted metadata.

• Utilized Wireshark to examine packets and find bugs in our system processing.
• Communicated with System Engineers to work out user interfaces, use cases, and requirements for the customers.
•  Established Jenkins builds and developed custom build scripts, including containerization
