About

Professional summary

I am a Senior AI Systems Engineer and Information Systems Engineer with a long software engineering background and more than six years focused on applied AI and machine learning. I design and deliver production-ready LLM, RAG, and agentic AI systems for international clients.

I specialize in translating ambiguous business goals into maintainable technical architectures with measurable evaluation criteria and reliable operations. My work spans the complete delivery lifecycle, from technical discovery and data ingestion through retrieval, orchestration, APIs, dashboards, testing, deployment, documentation, and handoff.

I build knowledge platforms using hybrid retrieval, vector search, PostgreSQL full-text search, knowledge graphs, metadata filtering, deduplication, and citation-aware workflows. I have delivered multi-tenant knowledge hubs, trade and compliance RAG systems, research pipelines, and persistent-context applications.

My agentic AI experience includes OpenAI, Anthropic Claude, Gemini, Ollama, LangChain, LangGraph, MCP, tool calling, structured outputs, model routing, memory, durable state, and multi-agent orchestration. I develop deterministic-first workflows that combine local and cloud models with automated validation and evaluation.

I work primarily with Python and production backend tooling, including FastAPI, Flask, Docker, AWS, Azure, PostgreSQL, MongoDB, and cloud automation. I also bring hands-on ML and NLP experience in forecasting, classification, regression, NER, semantic similarity, OCR, document processing, and model optimization.

I am a Top Rated Plus Upwork professional with a 100% Job Success score, over $200K earned, 48 completed jobs, and more than 2,791 tracked hours. I am based in Argentina and work remotely with clients through Upwork.
