EMANUEL MACHADO

Developing the APIS9 — a global product powering passenger information systems across trains, metros, and trams, currently deploying in Lisboa, Asia, MENA, etc.

• Built the Decision Tree widget — a visual rule-tree engine enabling operators to configure complex conditional display logic across dozens of interconnected rules per deployment.
• Built the Layout Manager — a Figma-like visual builder with wireframe drawing and component creation, drag-and-drop into layouts, sequenced playback with timings and transitions. Drove the backend data model redesign to support all the features.
• Grew unit test coverage from near 0 to +90% across the entire frontend system.
• Helped define coding standards and component architecture patterns across 20+ micro-frontend widgets in a previously chaotic, tech-debt-heavy codebase. Built and socialised AI workflow guidelines and tooling, promoting adoption across the engineering team.

Built project reports and data visualizations for UNAIDS, World Bank Africa, Humanitarian Action Overview and others. Emphasis on pixel-perfect rendering across languages, resolutions, and formats.

Male health subscription platform (medicine, supplements, blood tests). Focused on UX enhancement and A/B testing for data-driven decisions on user flows. Remote-first, global team.

Contributed to the Peacock TV and set-top box application. When the team shifted focus to a proprietary WebGL framework, maintained and stabilised the React codebase — patching critical bugs across specific device targets. Large team with established engineering practices.

Contributed to development and maintenance of multiple Magento-based online stores.

Joined a small development team supporting a shoe marketplace on Shopify. Initially fine-tuned the existing storefront, then took ownership of building a full B2B ordering platform — a Shopify app with custom frontend and backend, designed around a tailored order flow for retailers. Published an open-source npm package wrapping Shopify's Polaris component library for Nuxt (nuxt-polaris, still publicly available).

Worked on select freelance projects — landing pages and a management system for a local driving school — while exploring Nuxt and modern Vue patterns.

Joined as the first developer at a small creative agency and grew into lead of a 5-person dev team. Built hundreds of production projects spanning brand websites, landing pages, and e-commerce stores. Set up and maintained company and customers' infrastructure. Alongside the volume work, drove the agency's R&D side — designing and building custom interactive experiences for clients in the fashion sector presenting at international events. Built:

• NFC-powered interactive tables for shoe catalog browsing at trade shows.
• IoT baby-seat safety system prototype — sensor hardware, mobile app, web API, and automated emergency dispatch.
• Beacon-based web app for a fruit-farm visitor experience.
• Augmented Reality in cultural programs.
• Etc.

Led tech decisions and established the team's development workflow and “assembly line” for rapid delivery of standard projects while maintaining bandwidth for bespoke builds.
