Root Access: About Me

Background

Obsessed with computers from day one.

I started working with computers at an early age and have been fascinated by how systems work under the hood ever since. That curiosity grew into a career: in 2014, I joined Verizon Wireless as a System Administrator.

Today, I manage cloud infrastructure across Amazon Web Services (AWS) supporting multiple mission-critical Pega-based enterprise platforms, ensuring high availability, bulletproof disaster recovery, and automated maintenance.

“True reliability isn't the absence of failures—it's building architectures where failures are contained, self-healing, and unnoticeable to end users.”

Systems & Experience

System Administrator

Directly responsible for architecting, provisioning, maintaining, and monitoring enterprise-grade AWS infrastructure hosting mission-critical Pega BPM / PRPC applications across complex business units.

  • Orchestrated multi-tier AWS deployments including EC2 instances, VPC peering, Application Load Balancers, and S3 asset buckets.
  • Tuned Pega application server clusters, JVM garbage collection, and database connection pooling for optimal performance under load.
  • Engineered automated monitoring, CloudWatch alerts, and incident runbooks reducing mean-time-to-recovery (MTTR).
  • Collaborated with enterprise database and security teams to uphold compliance and zero-downtime rolling upgrades.

Computer Science Student

Pursuing an undergraduate degree in Computer Science, bridging practical systems administration with core algorithmic foundations, systems programming, and modern software architecture.

  • Designing optimized algorithms and evaluating asymptotic computational complexity across data structures.
  • Implementing memory-efficient programs, low-level process management, and multithreaded workflows.
  • Applying modern software engineering methodologies, unit testing frameworks, and version control hygiene.
