# ============================================================================= # Cedric Ancellin - Professional Competency Record (Section Overview) # ============================================================================= # Core Purpose: # A source-anchored, machine-readable record of Cedric Ancellin's demonstrated # engineering competencies as a founding CTO / principal platform architect: # what he has personally designed and built (or architected and supervised to # completion) across a large multi-tenant hospitality-commerce platform and # several modern-stack products. # # Governed by ../LAWS. Third-party technologies and vendors are named as the # concrete skill surface; this is professional background / track record, never # any prior employer's confidential internals or trade secrets. # # Last updated: 2026-07-04 # ============================================================================= profile: headline: > Founding CTO and principal platform architect who designs and builds production-grade, multi-tenant commerce platforms end to end: API engine, data warehouse, payments, integrations, security, frontends, and the AI/knowledge tooling around them. operating_model: > Every system recorded here was personally designed by Cedric. Delivery was either direct implementation or architecture plus technical supervision of an engineer executing to his design and review. The distinction does not change ownership of the design, the decisions, or the outcome. scale_signals: backend: "A very large, framework-free PHP platform with a shared business-logic library." api_surface: "Multi-version REST plus GraphQL, an OAuth-provider surface and an MCP surface." frontend: "An Angular/TypeScript operator SPA plus embeddable JS widgets." data: "Polyglot persistence and an analytics warehouse." payments: "Cards, crypto, wallets, gift cards, room charge and house credit behind one gateway abstraction." reporting: "A large operational reporting suite with a scheduled export engine." integrations: "Reservation, POS, PMS, payment, identity, messaging, marketing and guest-engagement vendors." applied_ai: "A self-hosted fine-tuned LLM, NLU, and a conversational assistant." knowledge_base: "A machine-readable YAML knowledge base with a from-scratch MCP server." # ----------------------------------------------------------------------------- # WHY THIS MATTERS # ----------------------------------------------------------------------------- track_record_relevance: > This is the concrete evidence base behind Cedric's track record. The hardest problems in hospitality technology, unifying two platforms, converging payments and compliance, building a shared data warehouse and analytics, hardening for enterprise, and layering AI on a unified foundation, map almost one-to-one onto competencies he has already delivered end to end (see payments_engineering, integrations_etl, data_engineering_warehouse, security_engineering, applied_ai_llm, ai_knowledge_engineering, and systems_architecture below). # ----------------------------------------------------------------------------- # COMPETENCY MAP (drill into each file) # ----------------------------------------------------------------------------- competencies: systems_architecture: $ref: "https://zc8.com/competencies/01_systems_architecture" scope: "Single front-controller request engine, multi-environment routing, multi-tenancy, statelessness + cache tier." backend_platform_engineering: $ref: "https://zc8.com/competencies/02_backend_platform_engineering" scope: "Large PHP monolith design, custom database abstraction, ID/encoding schemes, soft-delete + audit patterns." commerce_inventory_engine: $ref: "https://zc8.com/competencies/03_commerce_inventory_engine" scope: "Date-partitioned inventory, tier-yielded pricing, multi-layer breakdown engine, holds + publishing pipeline." payments_engineering: $ref: "https://zc8.com/competencies/04_payments_engineering" scope: "Multi-gateway checkout, Stripe Connect + Elements, refund engine, comps/cash, cart + fulfillment;
