Professional Timeline

My journey in technology and security

Senior Security Engineer

EchoStar / Dish Network | Denver, CO

Dec 2025 - Present
AWS Lambda Step Functions SQS GitLab CI/CD Python Terraform IAM KMS F5 Distributed Cloud Dynatrace ServiceNow
  • Architected an event-driven firewall change automation platform on AWS Lambda, Step Functions, and SQS, replacing a 5-day manual triage and approval process with sub-15-minute automated execution — earning VP-level recognition across InfoSec, IT Ops, and Security Architecture.
  • Built a GitLab CI validation pipeline that reviews every APIGEE gateway merge request across three repositories — linting nginx and JSON configs, enforcing a 19-field security questionnaire, and blocking merges on hard failures. Covered by 146 unit tests; the checks caught a live credential-leakage pattern and a whitespace defect that had caused a production deployment failure.
  • Modernized a 2022 standalone Java validation web app into a CI-native Python tool requiring no separate infrastructure, integrating the ServiceNow REST API for support-group validation and running post-merge scan assignment and deployment notifications as pipeline stages.
  • Built the perimeter security KPI pipeline: monthly automated collection of five posture metrics — WAF coverage, allowed-URL policy, GEO exposure, PCI Client-Side Defense coverage, and external attack surface — across ~317 F5 Distributed Cloud load balancers in 30 namespaces, rendered as an executive dashboard with trend lines.
  • Designed an evidence-based WAF enforcement workflow that analyzes 30 days of Dynatrace security event logs per load balancer to produce SAFE / REVIEW / NOT_READY promotion verdicts before moving policies from alert-only to blocking, with automated post-change validation.
  • Led response on a 13-hour production outage caused by a vendor F5 patch that silently tripped header-count limits — stayed on the F5 hypothesis through a multi-vendor bridge, drove the vendor to confirm and ship a fix, then led the VP-level retrospective and rewrote change procedures to prevent recurrence.
  • Consolidated 17 ad-hoc scripts accumulated over 18 months into 7 purpose-built tools on a shared client layer. Every mutating operation defaults to dry-run, requires an explicit apply flag, and gates production behind a second flag; wrapped the toolchain in a Flask dashboard for teammates without local Python environments.
  • Enforced least-privilege IAM boundaries, KMS encryption with automated key rotation, and private network topologies (PrivateLink, private SQS) across all automation workflows, maintaining zero public internet exposure.
