Work
Products shipped, used and improved over time.
A selection of projects that show four dimensions of my work: user impact, mobile depth, technical leadership and product autonomy.
For every project I distinguish the collective outcome from my personal contribution. The case studies detail the context, my role, technical decisions, constraints and available evidence.
