About Me

Bucharest, Romania

Hi, I'm Paulina - Full-Stack Developer with 8 years of experience, now focused on AI/ML Engineering. 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 graduate of Udacity's Agentic AI Nanodegree, AWS AI Practitioner certified, and currently preparing for NVIDIA Agentic AI Professional certification. My focus is on agentic AI architectures using LangChain, LangGraph, and LLM orchestration.

Beyond Code

When I'm not immersed in code or exploring AI technologies, I find balance through acrylic painting. Creating art helps me maintain creativity and perspective—skills that translate surprisingly well into designing elegant solutions and user interfaces. I believe that the best engineers are those who cultivate interests beyond their technical domain.
