  • Idea Management App for Organizations

    A powerful and intuitive idea management software helping organizations discover, evaluate, refine, and execute the most impactful ideas from everyone, everywhere. I was responsible for the front end and most precisely the migration from a jQuery-based monolith app to a single page application using Vue.js.

    The most challenging part was making a modern app work on browsers down to IE9. To achieve that I had to build many custom polyfills (for placeholders as an example), as well as custom packages (a date picker and a mentions component), and optimized for performance.

  • Custom React Components Library

    Having multiple products that are run by different teams and share the same design system, a need arose to build a components library so teams don't have to keep re-inventing the wheel.

    By working in close collaboration with the design team, we managed to build a full, in-house React components library that's easy to use, leverages the internal design system, and most importantly, speeds up workflow for developers.

  • Open Innovation Software

    I defined the architecture and led the front-end development for this serverless project. It was designed to allow organizations to participate in an open exchange of ideas without the constraint of company boundaries. By opening up to new sources of ideas, these organizations can accelerate their long-term innovation efforts.

  • Wealth Management Platform

    At Paxfamilia, I worked on developing and maintaining web-based software for creating complex financial models. It offered a full-screen auto-generated presentation with advanced user controls that leverages client-side data transformations to map, filter, and reduce, large datasets for display in interactive SVG charts.
