Summary

Independent consultant specializing in Azure cloud-native systems, full-stack .NET development, and AI-augmented engineering workflows. 17 years building distributed platforms, secure APIs, event-driven architectures, and web and mobile front ends, with a recent track record of using multi-agent AI orchestration to compress delivery timelines by 80%. I work embedded with engineering teams or as a full delivery partner, from system analysis through production code, bringing AI-accelerated workflows that compress weeks of work into days.

What I Deliver

Cloud-Native Development
Full-stack .NET Core microservices on Azure (Event Hubs, CosmosDB, API Management, Key Vault). Design, build, deploy.
Monolith Decomposition
Strategic extraction of legacy systems into event-driven microservices with validated API contracts and full test coverage.
AI-Accelerated Engineering
Multi-agent orchestration workflows (Claude Code, LLM tooling) that dramatically compress complex development timelines.
Architecture and Technical Strategy
C4 modeling, system design, security architecture (OAuth2, OIDC, JWT, Azure AD), and technical roadmaps.
Team Enablement
Mentorship, standards-setting, and knowledge transfer to elevate internal engineering teams during and after engagements.

Selected Engagements

Staff Engineer / Cloud Architect Jan 2020 - Feb 2026

Allegion US | Golden, CO

Progressed from senior engineer to staff-level technical leader across Allegion's mobile credential and cloud platform initiatives. Operated as the de facto architect for secure credential delivery, partnering directly with Google and Apple engineering teams.

  • Built a multi-agent AI orchestration system (Claude Code) that extracted 14 production endpoints from a monolith into a containerized microservice in 8 days, an 80% reduction versus the 6+ week manual estimate, with full test coverage and 1:1 API contract validation.
  • Architected and built Azure-based APIs for enterprise mobile credential delivery, integrating BLE, NFC, and digital wallet platforms (Apple Wallet, Google Wallet).
  • Decomposed critical legacy monoliths into event-driven microservices on Azure Event Hubs, improving scalability and system reliability across multiple product lines.
  • Led a cross-functional team of five engineers; mentored developers from junior through senior-lead level in distributed architecture, API security, and DevOps automation.
  • Defined Allegion's next-generation mobile credential architecture, balancing security, scalability, and reliability for enterprise-scale deployments.
  • Authored C4 diagrams, technical roadmaps, and architectural artifacts to align cross-team strategy and reduce ambiguity.
Consultant / Lead Developer Jul 2016 - Jan 2020

Wax Robots (Independent Practice)

Delivered custom software solutions directly to clients as an independent consultant. Full lifecycle: requirements through deployment.

  • Designed and built scalable RESTful APIs and cross-platform web applications (.NET, Angular).
  • Established CI/CD pipelines and DevOps practices for client teams.
  • Collaborated directly with clients to define technical requirements and translate business needs into working systems.
