Piero Alessandro Aguinaga Pizarro

I’m an ML/AI Engineer focused on building production-grade LLM solutions—especially RAG pipelines, LLM agent development, and multi-agent orchestration with LangGraph. At EY Perú, I led the technical development of an AI-powered tender risk assessment system on Azure, using Document Intelligence and OpenAI to ingest procurement documents, classify/summarize them, extract structured terms of reference, and surface compliance gaps and integrity risks.

I also redesign and harden real-world pipelines: I replaced a fragile web-scraping news pipeline with RSS feeds, deployed alerting on Azure Functions, and used GPT to summarize and classify integrity-related news for daily partner digests. In addition, I refactored integrity database scrapers to improve observability and scalability, and I build Azure OpenAI–based agent solutions using LangChain and RAG techniques—while delivering ETL workflows (including Alteryx-based financial statement standardization) with integrity checks to ensure data quality and compliance.
