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.
Focus Areas
What I work on
Multi-agent systems using Claude to automate STRIDE and ATLAS threat modeling, SAST triage, and RAG pipelines for document Q&A.
Serverless architectures, IaC with CDK/Terraform, multi-region deployments, and Bedrock-native AI pipelines.
Agentic threat modeling (STRIDE, ATLAS), SAST finding triage, vulnerability tooling, and security automation with LLMs.
Data structures, complexity analysis, algorithm design, and interactive visualizations.

A few highlights — see the full list on the projects page.
Upload any PDF and ask questions conversationally. Built on Amazon Bedrock (Titan Embed + Claude), ChromaDB, and FastAPI. Streaming responses with inline citations to every source passage.
Python microservices platform on AWS SQS, Kinesis, API Gateway, and PostgreSQL — modelling a real e-commerce order processing domain as event-driven independent services.
Notes, Q&A sets, and hands-on Bedrock projects across all five AIP-C01 exam domains — foundation models, agents, knowledge bases, guardrails, and responsible AI.
