Sr. Application Security Manager — automating AppSec with GenAI & agentic AI

18+ years building
secure, scalable systems.

I'm Teva — a Sr. Application Security Manager at Pattern, based in Salt Lake City. I build multi-agent systems using Claude to automate threat modeling — generating STRIDE and ATLAS threat models and triaging SAST findings at scale. Currently deep in RAG pipelines, agentic security tooling, and generative AI on AWS.


What I work on

AI / ML active

Multi-agent systems using Claude to automate STRIDE and ATLAS threat modeling, SAST triage, and RAG pipelines for document Q&A.

AWS Cloud active

Serverless architectures, IaC with CDK/Terraform, multi-region deployments, and Bedrock-native AI pipelines.

Cybersecurity active

Agentic threat modeling (STRIDE, ATLAS), SAST finding triage, vulnerability tooling, and security automation with LLMs.

Algorithms active

Data structures, complexity analysis, algorithm design, and interactive visualizations.
