Compact end-to-end demo of an agentic service: FastAPI + PydanticAI backend with tool calling and structured output, paired with a React MV3 side panel. Built as a small, readable reference for how an LLM feature is wired from UI to model and back.

Personal system that runs my own job search end to end: Claude Code as the orchestrator, custom skills and MCP servers, scheduled tasks, browser agents for multi-source collection, normalization and dedup of postings, matching against my profile, and document generation. Effectively a small ingest-and-matching pipeline of the same shape as a talent platform.
