Built a $2.5k client project (https://nudgrcrm.com/) using @Lovable + OpenAI API a while back. The app helps people keep their network strong with contact tracking, reminders, and AI-generated messages. My proposal was selected out of 50+ others, and the project ended with a 5-star review. This was the first big build that convinced me to quit my job back in May and go all-in on building with AI and no-code tools. These tools are genuinely changing what one person can create.

I built Idiolect, an open-source cross-lingual authorship attribution tool for OSINT and forensic linguistics. It compares writing samples across different languages using language-independent structural habits and multilingual style embeddings.
