I'm Mark Ellis - a senior ecommerce programme leader with over two decades of experience delivering complex programmes for large brands and retail technology providers. I've worked across ecommerce, international expansion, and large scale technology delivery with businesses including eBay, Amazon, Walmart, Google, and dunnhumby. I founded Immerced to bring that expertise directly to the programmes that need it most.
What I Do
Senior ecommerce programme leadership across strategy, foundations, and execution.
Strategy
Helping you make the right decisions before execution begins. From platform and technology selection to marketplace expansion, international growth, and commercial proposition - I bring the experience to shape the approach, stress-test the thinking, and ensure the programme is set up to deliver real business outcomes.
Governance
The difference between programmes that deliver and those that don't is rarely the technology - it's the foundations. I establish the operating model, team structure, ways of working, and governance framework that give complex programmes the best possible chance of success.
Execution
Owning the delivery end to end - not directing from a distance but leading from the front. Managing blended teams, driving stakeholder alignment, maintaining momentum, and keeping the programme on track from kickoff through to go live."
Who I Work With
I work with large or growing brands and retail technology providers who are serious about delivering complex ecommerce programmes. Typically that means businesses with ambitious growth plans, international expansion on the agenda, or large scale technology transformation underway - who need leadership that can operate across the full programme lifecycle.
