About

From .NET intern to GenAI platform engineer.

I’m a software engineer at Wells Fargo’s GenAI Platform Infrastructure team, where I build the production substrate that lets agentic AI run for 10,000+ users across five business use cases — policy, finance, investments, and more. The agents on the platform depend on MCP server integrations, multi-step reasoning, single- and multi-agent orchestration, tool-calling, and database connectivity. My job is to make all of that boring to ship.

I started in .NET and React as an intern at Sandhills Global, shipping production code across multiple releases for internal sales tools and customer-facing apps. The shift into GenAI happened during my final year at ASU — I’ve been compounding into LLM infrastructure ever since.

Outside the day job I keep my hands in the systems: I fine-tuned Llama 3.1 8B with QLoRA for an iRacing race strategist and built an eval harness that lifted its score from 29.7 to 78.5 while eliminating hallucinations. I built an autonomous shopping agent on AWS Bedrock with full Terraform infra. And I’m building a historical RAG engine over the 1912 Titanic inquiries that surfaces contradictions between witnesses instead of hiding them.

I’m an MS Computer Science student at Arizona State, finishing in December 2027. I write about what I’m building and learning on the blog, and review engineering books on the book reviews page.

Graduate coursework

Arizona State University — MS in Computer Science · Aug 2023 to Dec 2027

Knowledge Representation & Reasoning

Formal logic, ontologies, and reasoning systems — the spine underneath classical AI and the part most LLM engineers skip.

Artificial Intelligence

Search, planning, probabilistic inference, and learning. The breadth course that connects symbolic and statistical AI.

Bio-Inspired Computing

Evolutionary algorithms, swarm intelligence, neural systems — algorithms borrowed from biology, applied to optimization and search.

Hiring? Let’s talk.

I’m most useful where there’s production LLM infrastructure to design, evaluate, and scale — agent platforms, orchestration, RAG, evals, fine-tuning. Reach me at Guadalupe.Higuera@protonmail.com or grab the resume.
