Recent work from October 2025 through October 2026, followed by the earlier platform and cloud foundations it builds on. Internal systems are described through their engineering problems and public-safe outcomes.
Production software, cloud execution, and developer-platform reliability. The case studies show my responsibilities, the decisions behind the implementation, and the delivered result.
Wrote the product requirements and delivered live-data views, a personal work timeline, and shared caching for a team-owned engineering evidence product now in production. The work connects product definition, backend performance, and the acceptance checks behind reliable delivery.
Designed and stood up a shared knowledge repository with an agent-maintained wiki schema, hybrid retrieval, a structural knowledge graph, and a memory lifecycle. Repository-owned skills, hooks, and CI lint checks make research and decisions reusable across agent tools.
Ran Codex and Claude Code in company-controlled cloud sandboxes and returned inspectable patches. Added credential proxying, then implemented a keyless Codex pilot with per-run identity federation. The execution proof, pilot, and planned agent-team controls have distinct completion boundaries.
Built a versioned trust layer around a skill scanner, separating scan observations from policy decisions and emitting SARIF for CI. Packaged local pre-PR reviews, branch-review skills, and feedback hooks so trust practices can travel across repositories.
Hardened an event-driven separation-of-duties platform with observability, automatic incident creation, and processor consolidation. Worked through security findings, maintained vulnerability-data integrations, reviewed organization governance, and introduced agent tooling into the team’s own repositories.
The platform work this chapter builds on: cloud networking, secure data access, and the operational plumbing that lets other teams move fast. Earlier career work stays separate from recent delivery.
Led enterprise network consolidation to simplify NAT Gateway usage, orchestrated a DNS migration, and moved AWS ACM certificates from email to automated DNS validation. The work reduced cloud costs and the operational burden of fragmented network patterns.
Owned AWS account automation and replaced manual account and VPC deletion with an event-driven Step Functions and Lambda workflow. Built DNS verification and cleanup to address subdomain-hijacking risk, and introduced Dev Containers for reproducible onboarding.
I worked behind the customer experience for purchasing digital capabilities on John Deere equipment. During a hackathon, I built a secure data-ingestion pipeline that proved license data could serve internal teams while preserving isolation and access controls, helping make the case for an enterprise Data Engineering team.
At John Deere Financial, I helped turn an early API-gateway effort into a safer path for dealer software by architecting the platform's first external-facing API with role-based authorization and audit logging. That foundation later matured into a gateway used for both internal and external APIs.
