For a presales architect in BFSI — 6–8 weeks to demo-ready agent competency
You're already in the Claude ecosystem via Claude Code. The SDK exposes the same agent loop — streaming, tool use, MCP, subagents — that powers Claude Code itself. Build a research or proposal-drafting agent that directly accelerates your presales workflow from week one.
Weeks 1–2Role-based crews map naturally to presales storytelling: a research agent, an analyst agent, a deck-writer agent. Fast to prototype, easy to demo to clients. The "researcher → analyst → writer" pattern is a strong presales demo narrative.
Weeks 3–4The production standard your BFSI clients will ask about. Audit trails, state graphs, rollback, and human-in-the-loop approval flows are exactly what regulators want to see. Production at Klarna, LinkedIn, and Uber gives you credibility in sales conversations.
