I run the engines I build. ✨
Peru → Florida. AI engineer turned operator.
I'm Julissa. I build AI content engines — the full pipeline from keyword research to multi-agent drafting to publishing to social distribution. Right now I run that engine for seven brands, including this one.
I do it with my co-founder Alan. We co-founded Practical Works (our AI assessment studio) and we co-run Breezy Keys (short-term rental cohosting). I also operate my own Airbnb on the same stack, so my own customers are the unit test.
This site — julissa.work — is one specific lane: AI marketing operations and content engines for small teams. The engine that ships this blog also ships the blogs for Breezy Keys, Practical Works, Alan's fractional-CTO site, BeckonSites, ProofFix, and Resupply. That's the moat — I run my own tools on my own businesses before I run them on yours.
The stack: Mastra for orchestration, Vertex AI for inference, DataForSEO for keyword and SERP data, Ghost or WordPress for publishing, Late for social distribution, GCP for the runtime. n8n where it's still the right tool.
