PROFESSIONAL SUMMARY

Telecom billing mediation and revenue assurance engineer: 14 years as Sprint's highest-tier SME for wireless and wireline mediation (Nortel, Ericsson, Lucent AMA/CDR data), then senior infrastructure automation at Jabil and Raymond James. Saved $2M with an EDR routing application, raised mediation throughput 250%, cut alarm MTTR 50%, and led a $50M, 130-switch platform replacement. 25 years of production Linux with Ansible, Terraform, Docker, Kubernetes, CI/CD and ELK; fluent in Python, Perl, C and shell.

KEY ACHIEVEMENTS

• Saved $2 million annually by designing and leading development of an automated Event Data Record (EDR) routing application that collected switch usage records and distributed them to rating, billing, fraud and analytics systems (Sprint).
• Increased billing mediation throughput 250% by re-architecting record processing across parallel processors (Sprint).
• Cut alarm mean-time-to-resolution 50% by building observability and alerting on the ELK Stack across multiple mediation platforms (Sprint).
• Led the $50M replacement of Sprint's legacy billing mediation system (Marconi CEOS) with Openet FusionWorks across 130 switches - requirements, RFP, 12-vendor evaluation and selection.

PROFESSIONAL EXPERIENCE

• Founded and run an IT services firm serving 30+ client organizations with custom software (Python, PHP), web development and digital marketing for small businesses and federal contracts (registered vendor, CAGE 8PMQ9).
• Cut client deployment times 70% by automating infrastructure with Ansible, Terraform, Docker and CI/CD (GitLab CI, GitHub Actions) across AWS, Azure and GCP, improving multi-cloud reliability.
• Reduced deployment-related service disruptions 90% by refactoring a client's legacy monolith into containerized microservices.

• Reduced deployment time for critical iFactory infrastructure by 50% by building CI/CD build and release pipelines in Azure DevOps and Octopus Deploy with automated testing gates.
• Cut new-developer onboarding time 30% by containerizing all iFactory applications with Docker - breaking siloed apps into microservices - and deploying them on Kubernetes across approx. 112 manufacturing plants.
• Reduced manual configuration time 70% with a comprehensive Ansible playbook library for deploying, configuring and maintaining on-premises and cloud resources.

• Anchored Linux SME and Tier III application administration for the Capital Markets team's GBST Syn back-office trade-processing suite in a highly regulated financial environment.
• Cut release deployment times 50% with Ansible playbooks and Jenkins pipelines that automated releases across test and production environments with consistent configuration.

• Drove 30% growth in user adoption across 50+ enterprise clients by leading development and product management of codesigned's Microsoft SharePoint products "Intranet" and "Analytics" (.NET/C#).

• Anchored Tier III support, root cause analysis and on-call escalation for 14 years across every Sprint billing mediation platform, resolving critical issues with a 98% success rate and reducing service downtime 20%.
• Ran the Unix/Linux mediation pipelines that collected, parsed, validated, transformed, enriched and routed millions of wireless and wireline CDR/EDR records daily from Nortel, Ericsson and Lucent network elements to charging, billing and downstream systems.
• Recovered tens of millions of dollars in otherwise-lost revenue over 14 years by reconciling network elements, mediation and billing end to end and repairing corrupted CDR files that would have gone unbilled.
• Sustained 99.999% uptime (about 5 minutes/year) for 14 years across the 50-server bare-metal and virtualized RHEL/CentOS/Ubuntu mediation estate through disciplined patching, vulnerability scanning, hardware selection and vendor acceptance testing.

Built Fasttrack, a Ruby on Rails celeration-charting web app for behavior analysts at schools serving students with autism; trained 30+ educators, improving student progress tracking 20%.

Ran Unix systems and networks serving 3,000 subscribers for six dial-up-era ISPs; shipped first commercial software at 13.
