AI products, built solo

Two complete SaaS platforms — designed, engineered, launched and operated end-to-end by one person.

  • Integrated the Anthropic (Claude) API for AI course generation, tutoring and automated content moderation — with rate limiting and quality-verification tooling.
  • Shipped production infrastructure solo: public REST API, web push notifications, transactional email, automated SEO validation, security audits, and admin surfaces for support, campaigns and moderation.
