Technology Analyst

Dec 2023 - Jun 2026 • 2 yrs 6 mos

Provided Tier-2 and Tier-3 operational support for AWS production infrastructure, maintaining 99.9% service availability across multi-AZ EC2, VPC, and ALB setups. Built secure VPC topologies featuring public/private subnet segmentation, managed NAT Gateways, custom stateless NACLs with explicit IP deny rules, and S3 VPC Gateway Endpoints to eliminate NAT data transfer costs. Managed Terraform state centrally using Amazon S3 with server-side encryption and DynamoDB distributed mutex locking, mitigating race conditions across parallel pipeline executions. Automated server configuration and package management using idempotent Ansible playbooks, Jinja2 templates, and Ansible Vault for encrypted secrets management. Resolved P1/P2 production incidents regarding Application Load Balancers (HTTP 502/503/504 errors), DNS latency anomalies, and systemd service failures within strict SLA windows. Conducted post-incident Root Cause Analysis (RCA) and implemented automated health checks to prevent recurring outages.

Senior System Engineer

Dec 2023 - Dec 2024 • 1 yr

Managed containerized application deployments on Amazon EKS, configuring Horizontal Pod Autoscaling (HPA) and rolling updates with maxSurge and maxUnavailable controls for zero downtime. Hardened Docker runtime security by enforcing non-root users, dropping unnecessary Linux capabilities, and integrating automated Trivy security scans into build workflows. Configured the AWS Load Balancer Controller with Ingress path-based routing, target-type IP mode, and custom readiness probes. Monitored cluster performance and infrastructure health utilizing Prometheus, Grafana, and AWS CloudWatch.

System Engineer

Nov 2021 - Dec 2023 • 2 yrs 1 mo

Administered enterprise Red Hat Enterprise Linux (RHEL) and Ubuntu server fleets, overseeing storage partitioning, live LVM volume extensions, and POSIX file ACLs. Diagnosed Linux kernel and storage issues, including unlinked open file descriptor leaks (lsof +L1), inode table saturation, and zombie process accumulation. Automated routine administration tasks, node verifications, and backup procedures using defensive Bash shell scripts (set -euo pipefail). Maintained continuous deployment execution runs via Jenkins and configured scheduled cron automations with explicit PATH bindings.
