Experience

Vestra AI ehf., Slapp

• Co-founded Slapp, a social app where every user signs in with Icelandic electronic ID. Grew to 22,000+ verified users (over 5% of Iceland's population) with no paid marketing since launch in early 2026.
• Built the whole product with one co-founder: iOS and Android app (Expo and React Native), website, admin tools, advertiser portal and shop on a shared Convex backend. About 530,000 lines of TypeScript and 2,700+ commits in ten months.
• Launched Slapp+, a paid subscription with growing monthly revenue. Built a self-service ad platform (tilbod.slapp.is) and signed Nova and Domino's as the first major advertisers through direct sales.
• Built the feed recommendation system in-house: user and post embeddings (item2vec, Node2Vec) and a ranking model that is retrained every night and only deployed if it beats the current one.
• Built machine learning for user retention: a model that decides which push notifications to send (half as many notifications, 87.6% of opens kept) and a model that predicts which users are about to leave, tested against a control group.
• Led partnership talks with Síminn (Iceland's largest telecom). Before Slapp, built and tested about 30 product ideas across 58 repositories in 2025.
• In 2026 also built Melven, a football picks site with a published, checkable record, and the prediction models behind it, and, with Kristján, MCP servers and a chat widget delivered to Tixly.

Juni Digital

• Built websites and apps for companies and public institutions at one of Iceland's leading digital agencies, using Next.js, TypeScript, GraphQL and headless CMS (Contentful, Prismic).
