THOMAS LEAVY

SDA T2 (March 2024-Present)

• Championed adoption and structuring of Python AWS CDK for cloud infrastructure provisioning, producing reusable constructs and streamlining environment bootstrapping.
• Created and integrated helm charts and kubernetes deployment manifests for reproducible environment-specific releases across dev/stage/prod, enhancing deployment consistency.
• Developed Lambda for creating and updating AppConfig in addition to CDK to deploy
• Adapted T1Jenkins pipelines for T2 program use: modularized stages, added automated testing, and integrated SonarQube scanning and Nexus image promotion.

Sagittarius Ground (Feb 2022-March 2024)

• Established microservice framework to enhance operational status reporting.
• Engineered microservice architecture with lead engineer to convey health and status of operating environment to operator UI, improving situational awareness.
• Developed microservices in Python and Java to collect health and status information from various software, hardware, and network components, transmitting data to REST API for centralized access.
• Developed multi-stage Dockerfiles for each microservice and REST API, incorporating distinct stages for testing, development, and production.

Multi-Function System Services (Jan 2019 - Feb 2022):

• Designed, implemented, and tested a microservice in C++ for writing and storing instrumentation data off-board.
• Enhanced existing C++ microservices with additional functionalities to fulfill program requirements.
• Built simulator in Python for 3rd party hardware, facilitating interface with C++ software over TCP.
• Designed a simulator for program's interfaces in C++ to be used by vendors in integration.
• Used Docker in many different functions: containerized many of program's microservices, created docker compose file used by tactical image to load services, leveraged Prometheus to monitor containers and virtual machines running production tools/services with dashboards of live metrics and alerts.
• Created design documentation for multiple software components, enabling program to pass three critical design reviews.
• Led daily scrum meetings for team of 5-10 members, fostering collaboration and accountability.
