March 2023 - March 2026

Backend services, C# tactical map plugin work, distributed testing, simulators, CI/CD, and deployment tooling.

  • Built Java OMS adapters, TCP/UDP integrations, gRPC service work, and ActiveMQ-based workflows enabling interoperability across aircraft mission systems.
  • Designed and led automated BDD and data-driven black-box tests for distributed services, improving confidence in complex service interactions and hardware-facing integrations.
  • Reduced test-event deployment setup from 1-2 days to 4 hours by creating offline browser checklists, deployment scripts, and installers; enabled prep and regression testing in 1 week instead of 2.
  • Led teams at software integration lab events with live hardware, diagnosing issues, collecting data, validating fixes, and updating troubleshooting flows based on observed failures.
