About
Digital Creative and startup Tech Lead specializing in modern full-stack web engineering, cross-platform mobile development (React Native), and human-centered design at Hyper Island in Stockholm. Grounded in 15+ years of finance and HR executive leadership managing multi-entity structures and €6M operations, I seamlessly bridge business strategy, intuitive software delivery, and commercial growth.
As Head of Tech & Digital for early-stage startups and developer for the Japyo React Native app, I architect complete digital ecosystems while structuring non-dilutive innovation grant proposals (Vinnova, Mimer AI Factory). I also advise brands and independent practitioners on digital growth, audience scaling, and web tool optimizations.
Prior to transitioning into tech, I spent over a decade as Head of Finance & HR (Capel Paris), leading operational modernization across 10 retail stores and e-commerce platforms, rolling out SaaS & BI solutions, and driving cross-functional team growth.
Outside of development, I play competitive indoor volleyball for Rågsveds IF, actively volunteer at major tech events like TechArena (2025 & 2026), and enjoy vintage hardware restoration and retro gaming modifications.
