Beyond Noema, I design and ship full-stack products for clients and for myself. Several repos are private, so here's what they do: - Connect: a professional identity platform. Built the AI relationship-intelligence layer that turns saved contacts and notes into specific opportunities, using swappable model design. Row-level security with SQL assertions against Postgres. - HR Insurance (live, herenciarosario.com): Bilingual PWA for a client operating across states. Supabase lead capture, Resend email workflows, analytics. Replaced a manual intake process with an automated lead pipeline. - Hostreel: Built an automated social-marketing SaaS for vacation rental owners. AI converts property assets into platform-optimized video; a competitor/trend-monitoring layer informs what to generate, with a human approval step before publishing across social platforms. Live with tiered pricing. - Portfolio assistant: A scoped assistant on my site that answers questions about my work from a fixed corpus. - Write iOS and AI engineering breakdowns on Medium.
