- Architected and deployed Kubernetes clusters for self-hosting LLM models for a team of 50+, enabling our team to conduct research and develop more effectively. Deployed stack included Ollama backends for model hosting, Open WebUI for frontend and authentication proxy, and Langfuse for monitoring. - Acted as the primary liaison between T-Mobile cybersecurity teams and T-Advertising development teams, ensuring successful implementations of new security requirements and advocating for development teams’ requirements during new security rollouts. - Re-architected the existing public development and testing environments to be private, internal-only access to prevent service bugs and debug info from reaching the internet. Implemented the new environments and assisted developers with migrating their services with minimal disruption.- Migrated teams from VPN to Zscaler Private Access to support zero trust architecture, securing data and supporting least privilege principles. - Migrated 100+ existing DataDog alerts to Terraform, ensuring that alerts could be efficiently shared across teams and re-created or copied when needed. Created new synthetic alerts for APIs and websites to give better visibility into customer-impacting issues. - Prevented over $20,000/year of wasteful AWS spending by implementing reserved instances, creating automated tasks to delete unused infrastructure, and implementing lifecycle policies. - Contributed to the framework used to centralize deployment methodologies across four products, leading to reduced costs and reduced technical debt. - Led workshops on AWS and Terraform for developers, leading to more stable and secure infrastructure in AWS, as well as faster deployment times.- Implemented Gitlab Static Application Security Testing (SAST) and container security scanning across 30+ codebases in four separate products, enabling quicker security remediation and preventing secrets from reaching online code repositories.

Drove an initiative to make changes to the core Coalfire FedRAMP engineering product, reducing custom work required for engineers on projects. Discovered and proactively remediated bugs introduced by an AWS release in Terraform; fix was rolled out to every active project in the practice, saving 20+ engineering hours across delivery and product teams. Worked collaboratively across multiple teams towards customer satisfaction and creating quality project deliverables, including reports, advisory documents, system documentation, and production-ready cloud environments.Updated and improved configuration management playbooks designed to maintain security benchmarks such as CIS Benchmarks and DoD STIGs on systems, reducing manual engineering effort. Identified technologies and services not suited for environments seeking FedRAMP and DoD SRG certifications; researched and implemented replacements. Escalated project issues to engagement leads, management, and project oversight in a timely manner when necessary.
