Welcome to my website!

Hi, I'm Tania Papazafeiropoulou,

Front-End Tech Lead & Senior React / React Native Engineer

I specialise in building fast, accessible and user-focused mobile and web experiences. With 10+ years in front-end engineering and 2.5 years as a tech lead, I've delivered production React Native apps, led cross-functional teams, improved performance, and shaped product direction.

I'm passionate about:

  • React & React Native mobile development
  • Accessibility and performance
  • Mentoring engineers & cross-team collaboration
  • AI-assisted developer productivity
  • Using technology to create positive impact

I've spoken at React Conf 2019 and JS VidCon 2020 about how we built and scaled the Olio React Native app.
