##selected
A regulated gambling operator's core internal AI platform on AWS, built as the only engineer on the account. Bedrock AgentCore for agent runtime, memory and identity; RBAC-controlled RAG assistants with human review; custom-trained sequence-tagging models for copy compliance; and the Terraform-defined VPC boundary that keeps regulated data inside it.

A Rust learning platform built in Next.js and TypeScript. Multi-agent workflows on Claude and OpenAI generate challenges, evaluate solutions and adapt difficulty, backed by a Rust code-analysis engine for compiler-accurate evaluation and vector search over the content pipeline. MVP in three months, first paying subscribers onboarded.
