I run Halmerra, providing AI-assisted copywriting and applied research for online sellers, real estate agents, and early-stage SaaS founders. Three core services: - Etsy SEO listing rewrites (title, tags, description) built from real keyword research - Objection-handling script libraries for real estate agents, personalized to their market - Competitor intelligence briefs for SaaS founders, synthesized from public and commercial data sources I use AI throughout the research and drafting process to move fast, then personally review, verify, and refine every deliverable before it's client-ready. Working with clients across the US, UK, Canada, and Australia.
