Summary
👤
Senior🎓
Top SchoolMark Rubenstein is a Full Stack AI Engineer with 11+ years of hands-on experience building production-grade systems from React frontends to LangChain/LangGraph backends and Terraform-managed AWS infrastructure. He specializes in retrieval-augmented generation, agentic AI orchestration, and robust LLM evaluation/guardrails—skills grounded in an earlier career maintaining high-stakes government systems and distributed services. Mark has shipped production RAG platforms that ingest and regionally localize documents via AWS Textract, and built multi-step LangGraph agent pipelines for automated market research and feasibility scoring. He owns full IaC lifecycles (ECR/ECS, RDS/DynamoDB, VPC/IAM) and brings a tester’s rigor to model reliability, turning QA practices from Nike-era automation into reproducible LLM evaluation frameworks. Based in Portland, he thrives in fast-moving teams where the AI layer is a first-class product concern and prefers remote senior full-stack or AI engineering roles.
