Senior Mobile / .NET Engineer

I ship iOS and Android apps and the .NET services behind them. Twelve years in, I'm the engineer teams call when something has to be in production by Friday and still be in production a year later.

Summary01
Twelve years building software in .NET, ten of them shipping mobile apps to production. Four of those as the sole mobile engineer on a Canadian wallet product serving roughly 100,000 users, where I cut 28 releases in twelve months. More recently, leaning into AI-assisted delivery: a feature scoped at two months landed in three weeks, with 16 of 20 tickets passing QA on the first review.
