Tim Pinard

Principal engineer and applied AI architect. I design and build agentic AI systems for financial software.

Current work

I am the technical lead and architect for an AI assistant on a 16-year-old financial modeling platform at Synario. I own the architecture, the API contracts, the evaluation strategy and the development team.

  • Agentic AI systems: typed tools, model routing, streaming, failover
  • Evaluation: multi-turn eval cases that assert on tool calls and resulting state
  • Provenance: every figure the assistant reports cites the data it came from
  • Delegated identity: the agent acts with the user’s own permissions
  • Modernization: contract-first APIs as the seam for migrating a long-lived monolith

Projects

  • Personal CFO: a planning app where a Claude assistant builds the user’s financial model through conversation. 31 typed tools, an outcome-based eval harness, and cost per turn cut about 4x by model routing and prompt caching.
  • sdd-kit: a Claude Code plugin for spec-driven development with AI agents.
  • whatif-mcp: an MCP server for “what if” questions about personal finances, built by AI agents under sdd-kit.
  • Portfolio anomaly detection: unsupervised anomaly detection and attribution for investment portfolios.
