Strong experience with web/API architecture, relational and non-relational data, integration, authentication/authorization, testing, observability, and production operations.
Experience establishing secure SDLC/DevSecOps practices with Git, peer review, automated testing, CI/CD, dependency/container scanning, artifact promotion, and release controls.
Experience modernizing or integrating legacy enterprise systems under uptime, security, and compatibility constraints.
Working knowledge of containers, Kubernetes/OpenShift, Azure/government cloud, internal artifact management, and disconnected development.
Strong understanding of RMF/STIG, secure coding, data handling, auditability, vulnerability remediation, and production-readiness evidence.
Demonstrated people leadership, hiring, delegation, mentoring, performance management, conflict resolution, and cross-team delivery.
Experience briefing Government customers and translating mission outcomes into executable application plans.

Preferred Qualifications

Experience with AI-enabled application patterns, RAG integration, ServiceNow development/integration, workflow automation, or operational analytics.
Experience with microservices and modular monoliths, event-driven architecture, API gateways, message queues, and contract/schema governance.
Experience with SRE practices, performance testing, resilience, feature flags, progressive delivery, and accessibility.
