👋 Hi, I'm Ezequiel Sánchez

Enterprise AI Architect · SAP BTP Full-Stack · Agentic Systems

I build production AI systems on top of SAP BTP — where enterprise integration meets modern agentic architecture. Currently at Accenture as BTP & AI Specialist, where I ship AI-driven tools, remediate production security vulnerabilities, and architect agentic systems using the Anthropic Claude SDK and SAP AI Core.

Certified by Anthropic as a Claude Architect (Foundations, 2026) — agentic orchestration, MCP integration, Claude Code, multi-agent pipelines, and structured data extraction.


🤖 What I Build

  • Agentic systems — multi-agent orchestration, MCP servers, tool/schema design, human escalation workflows
  • AI-driven enterprise tools — procurement automation, anomaly detection, OData pipeline analysis
  • Secure BTP applications — CAP (Node.js), XSUAA, Destination Service, S/4HANA integrations
  • Production security remediation — OData injection, SSRF, broken access control, CORS misconfiguration, insecure file upload

🚀 Featured Projects

Scheduled CAP service that reads Purchase Orders from S/4HANA via OData, runs 3-way matching logic (PO / GR / Invoice), and uses SAP AI Core to interpret anomalies in free-text notes. Outputs structured reports and notifications to the procurement team — no write-back, full audit trail.
