- Shipped a Virtual Manager RAG answering building-specific questions across 3,000+ embedded document chunks — Claude and pgvector retrieval, isolated per building with RLS.
- Spun out Coop Timing Bill as a standalone product for external brokers and attorneys — multi-role auth via Postgres security-barrier views, migrated to Clerk with multi-tenant Azure AD OAuth.
- Designed a weighted vendor-routing algorithm (quality, completion rate, price, timeframe) with automated 5-minute escalation windows.
- Closed a live security gap exposing financial documents to unauthenticated users. Rescued a corrupted 81-migration history with a documented recovery path.
Where I've shipped
production, not coursework- Sole engineer on a paywalled video and community platform across 7 campuses. Grew the pre-launch waitlist past 50 members within a 150-seat founding-member cap and rate-lock.
- Built 14 Supabase Edge Functions covering auth, video, Stripe subscriptions, ticketing, and an OAuth2 Google Calendar integration — zero payment regressions on a live shared webhook.
- Cut video categorization from an engineering task to a 2-minute admin action by replacing hardcoded categories with a relational shelf model owned by non-technical staff.
- Secured a 4-tier role hierarchy across a 15-tab admin dashboard with RBAC, RLS policies, and CSP headers.
- Negotiated and closed a non-exclusive, perpetual license with a DTC fitness brand — full IP ownership and reuse rights retained.
- Trained and mentored 17 chapter leaders across a region of 1,000+ members. Retention rose.
- Founded an international girls-in-STEM chapter — 30+ members in the first year, weekly global discussions on AI.
