A.K.A JShez

I'm Jon, also known as JShez, a seasoned tech-leader hailing from London, immersed in the UK tech scene for two decades. Here I'm sharing how I build tech fast & lean, along with the realities of building a startup amidst the current UK environment.

These days I work in React. Prior to the emergence of Next.js, I co-authored a framework for isomorphic React.js apps, & I'm now dedicating my focus to truly cross-platform code-bases with React Native & Tamagui.

In Startup World, I'm a long-time listener, first-time caller. After finding my first job on Hacker News, 15 years passed before I jumped in & co-founded Now I want to discuss the challenges of entrepreneurship in the UK. I believe the UK has 1000s of future entrepreneurs blocked by an understanding gap, the mental block of traditional career norms, & fundraising roadblocks.
