Enterprise multi-tenant AI platform providing control surfaces for AI agents, a visual AI Workflow Builder, graph and vector knowledge stores, and voice agents, plus a no-code MCP Servers module and full SaaS management tooling.

• Built a no-code MCP Servers module allowing users to compose servers from a Tool Repository, attach credentials, deploy with API-key/OAuth authentication, and monitor analytics — enabling external clients including Claude, ChatGPT, Cursor, and VS Code to connect.
• Designed multi-tenant architecture with authentication, tenancy isolation, and feature gating driven by role/feature gates and a SaaS-vs-dedicated deployment-mode flag.
• Implemented hybrid knowledge stores combining graph and vector retrieval to power agent context and RAG workflows.
• Delivered SaaS management surfaces covering customers, billing, pricing, rate limits, guardrails, and audit logging, plus two embeddable chat widgets for customer-facing deployment.

AI-powered improvement platform for essay-based GCSE subjects, launching with English Language and Literature and architected to expand into History, Religious Studies, Sociology, Psychology, Economics, and A-Levels.

• Designed a deterministic 3-layer marking pipeline (AI feature extraction, rule-based grade mapping in pure TypeScript, AI feedback generation) that guarantees identical grades for identical submissions, eliminating the output variance typical of direct LLM grading.
• Architected a Turborepo/pnpm monorepo with a NestJS + Prisma/PostgreSQL API, Next.js frontend, and BullMQ workers handling asynchronous marking jobs.
• Built engagement systems driving daily revision habits through streaks, drills, and gamification, and a family plan giving parents visibility via automated weekly digest emails.
• Currently leading v2 roadmap execution to extend written-answer assessment coverage across UK education.
