At Swissquote, I worked in the platform-security squad on authentication hardening, fraud prevention and a client account migration combining two banking products. I defined API contracts with backend engineers, validated data migrations and drove penetration-test remediation across the iOS team.
At SpotAngels, I owned the iOS client end to end and delivered full-stack features across the app, a Ruby on Rails API and a Python service. I built the CarPlay app, integrated Apple Pay and Stripe, and worked on subscriptions and payment-path tests.
I also built and shipped App Store products as a sole engineer, and at Olvid modularised an encrypted messenger’s codebase and built discussion search. I’m currently working on an independent commodity contract automation prototype, where contract review and approval remain with people.
