Work Experience

Prod Support Engineer October 2022 – January 2026

SMARTSTREAM, JACKSONVILLE, FL

Middleware & Security Hardening: Engineered and hardened mission-critical middleware (Wildfly, ServiceMix, ActiveMQ) for global distributed interfaces. Designed high-availability message-broker clusters that ensured data integrity and resilience against regional outages.

Cloud Architecture & IaC: Architected and deployed production-grade AWS infrastructure (VPC, EC2) using Ansible and Semaphore. Standardized legacy environments into "Single Source of Truth" models, achieving environmental consistency.

Technical Leadership & Mentorship: Established enterprise engineering standards by authoring comprehensive runbooks and leading deep-dive technical training for junior staff in Linux kernel tuning, Docker orchestration, and Wildfly optimization.

Performance Engineering: Drastically improved system performance by diagnosing low-level Linux bottlenecks (I/O, memory, network). Achieved 99.9% uptime for high-volume transaction platforms through rigorous Root Cause Analysis (RCA) and the implementation of automated, self-healing maintenance scripts.

Deployments: Implemented continuous deployment pipelines to harmonize application state across Development, QA, Testing, and Production environments for major banking clients.

Incident Management: Harmonized incident response efforts for Sev1 and Sev2 events, restoring critical workflows and ensuring security standard adherence during rapid recovery operations.

Platforms as a Service: Implemented container orchestration strategies using Kubernetes and Docker; developed Grafana dashboards to monitor cluster health and automate resource scaling for mission-critical transaction platforms.

Systems Support Analyst II March 2022 – September 2022

FIDELITY INFORMATION SERVICES, JACKSONVILLE, FL

Global Traffic & Continuity: Architected Global Traffic Management (GTM) and automated failover strategies using Akamai and Resolve. Engineered seamless service continuity for mission-critical financial endpoints, maintaining zero-downtime during regional ISP or data center outages.

Performance Engineering & Optimization: Stabilized high-frequency transaction platforms by performing deep-tier tuning of WebSphere Application Server (WAS) on RHEL. Optimized JVM heap settings and garbage collection (GC) parameters, reducing application latency and preventing memory-leak-related outages.

Enterprise Observability & MTTR Reduction: Developed a comprehensive observability framework using ThousandEyes and Splunk. Engineered automated log forwarding and event-driven alerting that reduced Mean Time to Resolution (MTTR) for complex network and application-layer anomalies.

Disaster Recovery & High Availability: Standardized enterprise-wide HA architectures through the implementation of redundant system designs and rigorous Disaster Recovery (DR) protocols, ensuring financial data integrity and regulatory compliance.

Systems Operations Analyst Senior February 2007 – March 2022

FIDELITY INFORMATION SERVICES, JACKSONVILLE, FL

Mission-Critical Batch Automation: Designed and orchestrated global endpoint processing (SOD/EOD) using ASG Zena, Autosys, Orsyp, and FundTech. Guaranteed data integrity for high-stakes financial transactions by engineering resilient, automated scheduling workflows.

Platform Health & Escalation: Harmonized production health by serving as the senior escalation point for OpenShift, SQL, and Oracle support teams within the ServiceNow framework.

Enterprise Resource Optimization: Maximized server availability across Wintel and UNIX environments using IBM Tivoli. Proactively managed resource thresholds and directed high-tier support teams to resolve complex performance bottlenecks before they impacted users.

Data Protection & Secure Transmission: Engineered enterprise-wide backup success strategies using Veritas NetBackup. Hardened data-in-transit protocols by standardizing secure file transmissions via SFTP/SCP, ensuring full compliance with financial industry security standards.

Computer Support Intern May 2005 – October 2005
