  Orchestrator - governance for AI-generated code

  A platform that bakes engineering standards into AI-generated code and deterministically blocks commits that fall short. Spec-first and test-first discipline.

  500 green tests as a merge gate; standards no longer depend on manual review.

  Agentic assistant embedded in the ERP

  A custom tool-use engine built on Claude, with 8 safe tools that query Oracle in read-only mode and generate charts from real business data.

  Natural-language questions over live data, with identity and permissions enforced end to end.

  Air-gapped local AI platform

  Local LLMs deployed on GPU with RAG, for clients whose security policies forbid sending data to external services. Validated end to end with hardware benchmarking.

  Useful AI without a single record leaving the client’s network.

  OIDC Identity Provider + MCP server

  A custom OIDC identity provider with SSO and single logout, plus an MCP server that exposes live data to AI while respecting the identity and permissions of the person asking.

  One source of identity for both the ERP and the AI querying it.

1. Software Architect · Senior Full-Stack Engineer

   Current

   Rendev · Lima, Peru (Remote) · 2024 - Present

   End-to-end design and development of a full-stack ERP and applied AI platform for an enterprise manufacturing client.

   • Led the migration of a live manufacturing ERP from GeneXus to a full-stack TypeScript stack on Oracle: ~1,200 commits, 338 k net lines, 8 microservices, and 172 screens in 6 months.
   • Built an agentic AI assistant embedded in the ERP (a custom tool-use engine on Claude with 8 safe tools querying Oracle read-only), including AI-generated charts.
   • Shipped an air-gapped local AI platform (vLLM + Qwen2.5-7B + RAG on GPU) for clients under cybersecurity constraints, validated end to end with hardware benchmarking.
   • Implemented a custom OIDC Identity Provider (SSO with single logout) and an MCP server exposing live data to AI with end-to-end identity and permissions.
   • Designed and built Orchestrator, a governance platform that bakes standards into AI-generated code and deterministically blocks non-compliant commits (500 green tests, spec-first / test-first discipline).
   • Hardened ERP security with RBAC v2 (typed permissions plus an AST auditor that blocks drift in CI) and closed 4 HIGH vulnerabilities, including an IDOR, with regression tests.

2. Lead Front-End & UX Specialist · Platform Architect

   Current

   Bupry · Santiago, Chile (Remote) · Nov 2021 - Present

   Built and technically led a multi-tenant SaaS platform for extracting and analysing data from SAP systems.

   • Built and led a SAP data extraction and analytics platform with scheduled and on-demand extractions, exposed over REST and OData; initial stack in GeneXus (16 → 18) and MySQL.
   • Re-platformed the product to an architecture of 18 FastAPI microservices plus a React frontend, with PostgreSQL (multi-tenant Row-Level Security), MongoDB, and Redis, adding AI capabilities (RAG, LangGraph orchestration, Teams bot).
   • Ran an architecture and security audit that found and closed a critical authentication bypass (P0): removed ~10 unauthenticated endpoints, redesigned the middleware to deny-by-default, and fixed IDOR vulnerabilities.
   • Led the full cloud migration to Azure (Bicep IaC, private VNet, NAT Gateway with a fixed egress IP, CI with federated OIDC and zero passwords): 18/18 services in production.
   • Migrated 244/244 tables and 78 M+ records with count-based verification and no cutover window; optimised the heaviest table from 1h50m to 22 min (5×).
