Day 1 Value Add

20+ years of enterprise experience means knowing exactly where AI accelerates delivery — and where it creates too much risk. Developers are now all expected to leverage AI without authority or consideration as to whether it is appropriate, in what context, to what degree, and which technology is appropriate. Added value will be to bring the architecture discipline and governance to identify and keep mission-critical systems safe in AI environments.

Professional Summary

Lead Software Architect & Engineer with over 20 years of experience architecting, leading, developing, and delivering enterprise-scale OSS and BSS solutions for one of the nation's largest broadband telecommunications providers. Serves simultaneously as a Lead Software Engineer and provisioning architecture owner as a Lead Software Architect for the department solution design end-to-end from domain modeling and API contracts through deployment and production operations.

Leads teams of up to 20 engineers on $3M+ initiatives, driving architecture decisions that balance delivery velocity, security, and long-term maintainability. Deep expertise in workflow engine design, service provisioning, DOCSIS, PON/fiber optics, and VoIP across residential, commercial, and wireless product lines.

At the forefront of applied AI engineering: leads adoption of AI agentic tooling (Claude Code, multi-agent orchestration) to accelerate delivery and reduce contractor dependency by 50%. Architects large-scale source-to-source migrations across ~200 repositories using OpenRewrite, and drives disciplined AI Software Design practices that produce maintainable and auditable systems that protect the organization from "vibe-coded" non-deterministic outcomes. Subject matter expert for enterprise AI vendor evaluations, security and privacy considerations (masking, OWASP), and use-case–driven agentic workflows.

Dual master's degrees in Information Systems and Business Administration bridge deep engineering execution with strategic enterprise planning. Experienced leading OSS integrations with Calix, Nokia, Cisco, Altiplano, Comcast, Verizon, and T-Mobile. Committed to mentoring, knowledge transfer, and building high-performing teams.

Key Projects & Achievements

Next-Generation Provisioning Workflow Engine (2025-Present)

Architected and built a new event-driven provisioning workflow engine from scratch supporting all provisioning domains, delivering approximately 10× throughput improvement and laying the foundation for AI-assisted agentic automation in 2026.

Cox Mobile / Wireless MVNO Launch (2022–2023)

Principal development lead for Cox's wireless product entry: redesigned all NDEL and Swap use cases, integrated new BIS APIs, eSIM, T-Mobile and Verizon back-office, and a new CCM model — first wireless provisioning to production.

PON / Fiber & XGSPON Provisioning (2014–Present)

Development lead for residential and commercial fiber provisioning on Nokia XGSPON, Calix, and Altiplano platforms. Delivered 1GIG, 2GIG, multi-gig symmetrical, and 10GIG speed tiers and DOCSIS 3.1/4.0 across the Cox footprint.

Kubernetes & Cloud Infrastructure Migration

Led full platform modernization: Solaris 10 → RHEL VMs → OpenShift → Rancher → Google Anthos. All Core 2.0 provisioning microservices migrated to cloud-native Docker/Kubernetes with automated Jenkins CI/CD pipelines.

DevSecOps & Security Compliance Program (2020–Present)

Established automated Veracode, SonarQube, SonarLint, and PrismaCloud container scans across the provisioning portfolio; achieved and sustained Veracode scores of 97–100; led OWASP-standard compliance for all Java OSS services.
