Built Skcript's email and notification service from scratch — pulled it out of a legacy Ruby system so every product routes through one place.
It's handled 500K+ jobs in six months with zero failed deliveries. Redis queues, Postgres transactions, and a 3-try retry path keep it honest.
Added pixel-based open tracking and URL shortening, so the dashboards show who opened and clicked in near real time.
The pipeline behind it logs every step of an email's lifecycle, so nothing disappears silently under load.
Shipped FeatureOS Mobile end to end with React Native + Expo — changelogs, roadmap boards, voting, and a searchable knowledge base in one app.
Wired in Apple Sign-In, Sentry, and React Query for typed APIs and caching across iOS and Android.
