Open to senior architect and IC roles building agentic systems. If your team is building production agents and wants someone who has shipped one end-to-end — let's talk.

Buyer Team is my flagship: an autonomous, multi-tenant procurement-negotiation platform I architected and built end-to-end on Amazon Bedrock AgentCore and the Strands Agents SDK.

It ingests purchase requisitions, classifies them on the Kraljic matrix (profit impact × supply risk), routes each to the right negotiation strategy — spot bid, competitive auction, risk-managed partnership, or strategic engagement — and runs the full cycle autonomously: supplier invitations, multi-round bidding, evaluation against governance rules, and Purchase Order assembly. All audited, at minimum AI cost per negotiation via a four-layer cost-optimization architecture.

Stack: Strands Agents SDK · Amazon Bedrock AgentCore (Runtime, Memory, Gateway, Identity) · Python 3.14 / FastAPI · Next.js · MCP (SAP S/4HANA · Oracle Fusion · Coupa) · multi-tenant by design · OWASP Agentic 2026 mapping · MITRE ATLAS threat model · 7-year immutable audit trail · GitOps with Terraform & GitHub Actions.
