## About

```text
At Nacif Software Development, I build AI-driven legal tech and e-commerce products for US clients. My LangGraph agents doubled new-client acquisition, improved conversion by 60% through technical SEO, and cut lead-qualification steps by 50%.

I ship end to end across Node.js, TypeScript, React, Next.js, Ruby on Rails, APIs, databases, and cloud deployment. I've also built RAG ingestion for 1 GB+ documents, deployed Rails and Elixir services on AWS, and created internal tools that reduced spreadsheet build time from about 30 minutes to 5.
