EMANUEL MACHADO

Developing the APIS9, subsystem of the ALVEA solution — 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.
• Grew unit test coverage from near 0 to +90% across the entire frontend system within the first few sprints, establishing a robust testing culture.
• 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.
• Helped define coding standards and component architecture patterns across 20+ micro-frontend widgets in a tech-debt-heavy codebase, improving overall confidence and delivery velocity.
• Currently leading the redesign and rewrite of critical operator widgets (Transit Management & Train Route), modernising legacy systems to handle real-time train telemetry, journey/mission scheduling templates, and manual override controls for passenger displays (delays, track changes, platform adjustments, etc).

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

Male health subscription platform (medicine, supplements, blood tests, etc). Focused on UX enhancement, translating designs to code pixel-perfect. Implemented multiple flows/dynamics, with a strong focus on A/B testing variants for data-driven decisions. Remote-first, global team with outstanding processes and environment.

Contributed to the Peacock (streaming service) TV and set-top box application. When the team shifted focus to rebuild the app with a proprietary (and much more efficient for low end devices) WebGL framework, maintained and stabilised the React codebase — patching critical bugs across specific device targets. Large team with well-established engineering practices.

Contributed to development and maintenance of a few 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 — an app built against Shopify's API 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).

Worked on select freelance projects — landing pages for local businesses, 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 and deployed hundreds of production projects spanning brand websites, landing pages, and e-commerce platforms. 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. Some examples include:

• NFC-powered interactive tables for shoe catalog browsing at trade shows, IoT showcases, etc.
• Beacon-based web app for a fruit-farm visitor experience.
• Augmented Reality in cultural programs.

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.
