My first product project: turning a technically complex activation into a simple customer flow.
We started from scratch to enable eSIM activation for o2 customers using Apple Watch. I gathered requirements, aligned different departments, worked with Apple on technical constraints and guided external agencies towards a focused experience with as few decision steps as possible.
Problem
Make a complex technical process feel effortless.
eSIM activation involved multiple teams, technical dependencies and strict platform requirements. The customer experience still needed to feel straightforward: users should be able to activate their service without unnecessary decisions or confusion.
Product work
Align the constraints, then challenge them where they create friction.
I gathered requirements across departments and ran workshops with Apple to understand the technical boundaries. I then translated those requirements into a clear product direction and guided external agencies as they prepared the wireframes. Where technical solutions created unnecessary complexity, I brought the teams back together to explore simpler alternatives.
Outcome
A focused activation experience that scaled to 500k+ installations.
The result was a concise activation flow that reduced unnecessary decision points and brought customer, business and technical requirements into one coherent experience. The web launch went on to reach more than 500k installations, making this the first project where I applied product management skills end to end: turning a complex problem into requirements, aligning stakeholders, guiding the solution and making trade-offs to improve the customer outcome.
