On-chain analytics platform that helps crypto investors read market data. I take projects from start to finish, working across the React frontend and the Node.js services behind it.

• Took a new metrics page an exec had prototyped and got it into the product. A lot of the data behind his version didn't exist, so I went through it with him section by section and proposed things we could actually build, then put each piece behind a feature flag so we could ship and adjust as we went.
• Moved around 1,000 charts from Highcharts to µPlot to fix slow rendering on dashboards with several charts at once. I wrote a translation layer that converted the existing configs, so none of the charts were rewritten by hand.
• Built the AI tooling the data science team used to migrate their own chart configs, instead of everything queuing behind me.
• Built an AI chatbot that lets users ask about on-chain data in plain language, plus MCP servers and a hosted agent that makes small edits and reviews pull requests.
• Day to day: server-rendered React, TypeScript, Redux and Redux-Saga, a Node.js and Strapi backend, tested with Jest and Cypress.

Zurich-based platform connecting brands with creators for marketing campaigns. Fully remote from Spain. I worked on three of the main tools.

• A canvas editor for placing branded stickers and logos onto uploaded photos, covering the image compositing, drag and drop, and positioning.
• A creators app where creators submit their artwork and brands review and approve it.
• An admin platform where brands manage campaigns, budgets and creators, including the budget and expense reports.

One of the largest language learning apps.

• Built the design system: the design tokens and a set of reusable React components used across all of Babbel's apps.
• Worked on moving a legacy Rails monolith over to single page apps.

Holiday rental marketplace.

• Part of the team moving server-rendered Rails views over to React single page apps. Worked out how to fit React into the Rails asset pipeline and turned it into a pattern the team reused for the ports that followed.

Online betting. I joined as a web designer and moved into the frontend team.

• Two years building dynamic banners with live odds. Several ran in production for years on high traffic sites including oddschecker.com and livescore.com.
• Two years in the frontend team building shared components with ERB templating in Rails, Sass/SCSS and CSS animations, and JavaScript with jQuery and AngularJS. Handled the build setup with Grunt and Gulp.

A React wrapper for materialize-css. Around 1.4k stars on GitHub and 11k npm downloads a month, often used as a starter kit by people learning React.

• Most of the work is reviewing other people's pull requests and deciding what belongs in the library. I help contributors through problems across React, Webpack and Jest, which usually means explaining a tricky idea clearly rather than writing the code myself.
