Cloud Migrations and Infrastructure

  • Led a seamless migration of a 1.4TB Postgresql instance to AWS Aurora, ensuring minimal downtime.
  • Designed and implemented secure AWS architectures with VPC peering and Transit Gateways, supporting hybrid cloud environments.

Automation and Cost Optimization

  • Developed AWS Lambda functions to automate database availability, reducing costs by 30% compared to reserved instances.
  • Created multithreaded Python scripts to synchronize over 15TB of data from on-prem NFS to AWS S3, improving data retrieval efficiency.
  • Led initiative to utilize Tenable API to complete scanning and vulnerability remediation

CI/CD and Containerization

  • Implemented Jenkins CI/CD pipelines, reducing deployment time by 40%.
  • Implemented Quality of Life improvements for Release paperwork automation
  • Moved backend services to containers in AWS Fargate, optimizing resource usage and scalability.

Monitoring and Performance Optimization

  • Deployed and Managed ELK Stack (Elasticsearch, Logstash, Kibana): Implemented a centralized log management solution using ELK, enabling real-time monitoring and log aggregation across multiple services. This resulted in a 30% reduction in time spent diagnosing and resolving system issues by allowing instant access to logs and detailed search queries.
  • Proactive System Monitoring: Set up AWS CloudWatch to monitor key system metrics (CPU, memory, disk usage) and trigger automated alerts, leading to improved system uptime and faster response times to incidents.
  • Cost and Performance Optimization: Analyzed resource utilization patterns and implemented autoscaling policies to ensure efficient use of cloud resources. This resulted in a 25% reduction in AWS costs without impacting performance.
  • Built Custom Dashboards: Created custom monitoring dashboards using Kibana and Grafana, tailored to provide insights into application performance, user activity, and error rates. These dashboards helped stakeholders visualize critical data in real time, improving decision-making processes.

Reporting and Insights

  • Automated Reporting for Performance Trends: Developed Python scripts and automated queries to generate performance reports, highlighting key metrics such as server response times, error rates, and system throughput. These reports were distributed to the development and operations teams to assist in identifying bottlenecks and optimizing application performance.
  • User Behavior Analysis: Used log data to analyze user activity across applications, identifying usage patterns and peak traffic periods. These insights led to capacity planning adjustments that improved load balancing and reduced server strain during high-traffic events.
  • Compliance and Audit Reporting: Worked closely with the compliance team to generate reports for SOC, FFIEC, and FDIC audits. Implemented automated data collection systems to ensure that all security and system activity logs were properly archived and easily accessible for auditors.

Certifications

  • AWS Cloud Practitioner Certified AWS Certification Badge
  • Working towards AWS Solutions Architect and SysOps certifications
