Precious O Oritsedere

Software engineer · JavaScript, TypeScript, React, Python, Node.js · London

I'm a software engineer in London. I mostly build with JavaScript, TypeScript, React,Next.js, Vue and Node.js. I also use Python for data work and automation. I like understanding the whole product, not just the UI. And I am always exploring new tools and tech stacks.

I currently work at the Open Data Institute, where most of my time goes into the OpenActive dashboard and Solid File Manager. Before ODI, I worked on products in education, fintech, healthcare and the creator economy.

Since 2019, I've built my career across Nigerian, UK and distributed international teams. Accessibility is part of how I build, not something I leave until the end. I've also led a small frontend team, contributed through Outreachy, and mentored other frontend developers.

    • I wrote @solid/react-component so our Solid apps could share the same login UI, provider picker and authentication guard.
    • On solidproject.org, I’ve added a skip link, keyboard-accessible mobile navigation, better semantics and labels, stronger contrast, and mobile layout fixes.
