luckycat.ie

• Pre-launch restaurant SaaS built as one codebase for all tenants: a React/TypeScript ordering app, an operations dashboard (shifts, stock, payroll, cash-up) and AI-assisted sales tooling, backed by Supabase.
• Tenant data is isolated in PostgreSQL with Row-Level Security and checked by Playwright cross-tenant tests. Payments built on Stripe Connect (onboarding, direct charges, application fees); hosted on Cloudflare Pages.

luckycat.ie/pitchpilot

• White-label field-sales app whose Wingman copilot answers pricing and contract objections from each product's own documents.
• A Supabase Edge Function embeds the question with Gemini, retrieves the top 6 chunks with pgvector filtered to the active product and answers with Gemini Flash-Lite, logging its sources; model keys stay server-side behind a role-based JWT and a daily cap. Replaced an IVFFlat index with exact search after recall collapsed on a small corpus; re-indexing embeds only changed chunks.

luckycat.ie/synergy

• One contract per app defines identity, input/output schema, failure codes, safety rules and implementation binding; MCP tool annotations are derived from it instead of being written twice.
• A static safety lint rejects contracts that move money without confirmation, make financial writes without an idempotency key, or allow anonymous writes. Demonstrated on a sample café app.

Open source (MIT) | github.com/augbastos/Deputy-MCP

• Python MCP server that lets Claude answer roster questions ("When do I work next?") from a live Deputy account: 11 read tools, plus 5 write tools that exist only when DEPUTY_ALLOW_WRITES=true.
• OAuth, API-token or calendar sign-in; tokens kept in the OS keychain and sent only to *.deputy.com, with errors scrubbed of secrets; CI with security scanning.
