Project Chevron

• Architected and deployed an Agentic AI Copilot/Agent framework that processes natural language prompts from management to analyze ticket metadata, instantly delivering strategic operational insights such as top closing tickets and pending resolution bottlenecks.
• Engineered an automated DigiCert Certificate Lifecycle management system that centrally discovers and tracks SSL/TLS certificates across infrastructure devices (including Palo Alto Panorama), consolidating expiration data into a centralized visibility dashboard.
• Designed a proactive alerting mechanism for certificate renewals, mitigating outage risks by automatically triggering team notifications for expiring certificates prior to ServiceNow ticketing integration.
• Developed and deployed daily network automation solutions using Python and Ansible to streamline continuous operational workflows and eliminate critical manual bottlenecks.
• Architected automated Change Management pipelines by integrating ServiceNow Flow Designer with Azure DevOps to automatically trigger pre- and post-validation scripts during device upgrades.
• Streamlined device verification and reporting by implementing scripts that execute automated state-checks, perform differential analysis (diffs), and output dynamic HTML logs for engineering review.
• Built interactive Power BI dashboards to provide high-level operational visibility, tracking automation success rates, network health metrics, and key performance indicators (KPIs).
• Implemented automated cross-platform alerting via Power Automate to deliver real-time pipeline status updates, accelerating incident response and team situational awareness.

• Developed automated file transfer systems using Unix scripting to improve vendor-to-vendor communication and reduce manual errors.
• Project Constellation

• Led the design and development of a custom software solution that increased system efficiency and reduced operational costs.
• Project Muji

• Led incident management and root cause analysis, optimizing system stability and improving overall uptime.
• Project AT&T

• Automated billing systems and report generation using Python and shell scripts, reducing system downtime and manual errors.
• Implemented SRE automation to enhance production efficiency, improve system performance, and minimize recurring issues.

• Delivered technical support for billing systems and reporting tools, maintaining production stability through proactive issue resolution.
