I build AI systems that run inside enterprise infrastructure.
I design and ship production-grade agentic systems on SAP BTP — combining deep enterprise integration experience with hands-on AI architecture. At Accenture I remediated 15+ production security vulnerabilities and built AI-driven procurement tools on SAP AI Core. Certified by Anthropic as a Claude Architect (Foundations, 2026).
Available for remote senior and architect-level roles.
About Me
I'm Ezequiel Sánchez — an Enterprise AI Architect and full-stack SAP BTP developer based in Rosario, Argentina.
My work sits at the intersection of enterprise integration and modern AI architecture: designing secure BTP landscapes, shipping agentic systems against live S/4HANA data, and bringing production security discipline to every layer of the stack.
At Accenture I became the team's primary security reference for BTP applications — remediating OData injection, SSRF, broken access control, insecure file upload, and CORS misconfigurations across multiple production systems. I also built AI-driven procurement tools using SAP AI Core and delivered client enablement at Ternium that received direct client recognition.
In 2026 I earned Anthropic's Claude Architect – Foundations certification, covering agentic orchestration, MCP integration, Claude Code, multi-agent pipeline design, and production context management.
I hold SAP certifications in CAP Backend Development and Fiori Application Development, and I'm completing a Systems Engineering degree at UTN Rosario.

Featured Work
PO Analysis Agent
Enterprise AI · SAP BTP · Production
Agentic procurement system that reads live Purchase Order data from S/4HANA via OData, runs a 3-way match (PO · GR · Invoice), and uses SAP AI Core to analyze free-text notes for context the business logic can't see — distinguishing genuine errors from partial discounts, delivery delays, or documented exceptions. Outputs a structured daily report to the procurement team with conflict type, AI assessment, and recommended action. No write-back to S/4HANA by design — human review before any financial action.
Architecture
- Trigger → CAP scheduled job (daily)
- Data source → S/4HANA OData via Cloud Connector + Destination Service
- AI layer → SAP AI Core — anomaly detection on free-text PO notes
- Output → Structured JSON report + procurement team notification
- Security → XSUAA auth · credentials via service binding · read-only S/4HANA access
Multi-Tool Agentic System
Anthropic Certification Project · 2026
Complete agentic loop built with the Claude Agent SDK — MCP tool integration, PostToolUse hooks for policy enforcement, structured error propagation, and human escalation workflows. Demonstrates production-grade agentic patterns beyond the basic tool-call loop.
Multi-Agent Research Pipeline
Anthropic Certification Project · 2026
Coordinator-subagent architecture with parallel Task tool execution. Structured claim-source mappings for provenance tracking and coverage gap annotation. Built to demonstrate how multi-agent orchestration handles partial failures without collapsing the full pipeline.
CI/CD Code Review Integration
Anthropic Certification Project · 2026
Claude Code integrated into an Azure DevOps CI pipeline using the -p flag and --output-format json. Multi-pass per-file review architecture with prior-findings context injection — so later review passes know what earlier passes already flagged.
SAP BTP Microservices
Enterprise integration reference
Enterprise microservices architecture using SAP CAP, integrated with S/4HANA and external cloud services. Reference project for CAP service design, XSUAA security, and multi-system integration patterns.
Let's Work Together
I'm open to senior and architect-level remote opportunities — particularly roles at the intersection of enterprise integration and AI systems.
If you're building something that needs both SAP BTP depth and modern AI architecture, I'd like to hear about it.
