Experience

Technical Product Manager & Product Owner

2024 - Present

Ellum AI · Remote · AI SaaS

  • Own the product end to end for an AI marketing platform, from the original pilot through a V2 architecture scoped across 11 milestones and 7 epics.
  • Re-architected the content engine from single-shot prompting to an orchestrator that routes work to specialised agents, skills and tools, so new capabilities ship without changes to the core platform.
  • Defined an MCP-compatible capability registry (DeepEllum) covering agents, skills, tools, CLIs and integrations, with subscription-aware installation so entitlements map to what customers pay for.
  • Specified an AI-enabled onboarding flow capturing brand identity, goals and audience as structured context for every downstream agent, plus a social publishing rewrite across LinkedIn, TikTok and YouTube.
  • Ran the pilot with ~50 users, converted feedback into a prioritised roadmap, and produced the investor-ready materials used in fundraising conversations.
  • Lead a distributed team of 8 across backend, frontend, design, QA and marketing on a weekly sprint and standup cadence.
