Hi, I'm Paulina — a full-stack engineer now focused on AI/ML systems. My petroleum engineering background taught me to think in layers and approach complex systems methodically - skills that have proven invaluable in both software architecture and AI development.

I specialize in building production-grade applications with Next.js, NestJS, and AWS, holding AWS Solutions Architect Professional certification. I've led teams and architected scalable solutions for both startups and established companies.

Today, I'm building intelligent systems using modern AI frameworks. I'm a Udacity Agentic AI Nanodegree graduate, AWS AI Practitioner certified, and currently preparing for NVIDIA's Agentic AI Professional track. My focus is on agentic AI architectures using LangChain, LangGraph, and LLM orchestration.
