## About

```text
As a Freelance Software / AI Engineer, I design and deploy RAG pipelines that turn unstructured documents into usable answers. I also build and improve React applications.

I build automation agents for different parts of software development pipelines and own the end-to-end pipeline, from cloud infrastructure and data models to APIs, UI, and deployment.

At Servicetitan, I developed components and layouts for the content team and worked with SEO, CRO, and Content colleagues to deliver features. I also improved Core Web Vitals across three sites and added structured data to support crawling.
