Geoffrey Hug

Worked as part of a team of senior frontend and backend engineers on Hume, a graph-intelligence platform used by law enforcement and security agencies to make sense of their large amounts of data. - Architected and shipped new features for Hume, working in a large and complex Vue 3 + Vuetify frontend. - Owned data sources matrix editor feature in collaboration with product, using AI-assisted prototyping to create a fast iteration and feedback loop against shifting requirements, then refactored it to be production-ready once settled. - Built internal tooling and AI skills to automate analysis of security vulnerabilities (CVE/GHSA), significantly speeding up assessment, customer notification, and the delivery of security fixes. - Was a primary contributor to the Playwright (Java) E2E suite, expanding coverage of critical features, building full coverage for new ones, and establishing a shared formatting standard across the codebase to cut review friction and diff noise.

Hume.js is the visualisation library used by Hume. It allows to render graphs using a WebGL and Three.js rendering engine. - Lead core performance optimizations, resulting in 50% faster data loading times and significantly improved UX for large relational datasets. - Reduced application build times from 6 minutes to 15 seconds, vastly improving team debugging and ability to test in-app. - Implemented advanced visual features including SDF fonts, infinite animations, and custom data visualizations. - Consolidated repeated buffer-management patterns in the rendering engine into reusable, declarative abstractions, cutting duplication, simplifying buffer management, and making it clearer what triggers re-renders when library data objects change. - Developed a Svelte application from scratch to support R&D for graph layout algorithms, alongside researching WebAssembly (C++) integrations for complex layouts. - Overhauled validation system with a solution based on customizable schemas and a fault-tolerant error-handling policy which improved ease of use and DX.

Built a Svelte + canvas visual map editor for a platform of 2D interactive web spaces (virtual visit and collaboration), working directly with the founder and CTO. - Implemented a polygon-drawing system for defining interaction zones, with fully editable geometry: draggable vertices, segment splitting, and point insertion/removal. - Wrote a custom 2D vector-math library to power the editor’s geometry and interactions. - Built an inspector for configuring elements, placing content anchors (images/video), and defining parameterized actions triggered by each interaction. - Integrated with the backend API for map loading and change sync, with toggleable auto-save.

KPI-Deck is a data analytics and business management dashboard for Amazon sellers. Main challenges were to process very large amounts of data from inconsistent sources and present it in a heavy dashboard UI that makes sense to users. As part of a small team (2 founders, CTO, 1 other dev), I've been involved in the design and architecture of most features. In particular, I've proposed a design for a critical feature that would help us stand out from competitors by providing an easier and more intuitive way for users to manage their cost of goods based on their supply orders.

Customiiz is a custom e-commerce platform for crowdfunded shops of customizable products (hit the sales goal and production starts, miss it and customers are refunded). - Handled architecture, project management, execution and deployment in collaboration with the CEO and his assistant. - Built an interactive product-customization tool: place, scale, and rotate artwork over per-product print zones, with embroidery preview and print-ready file generation. - Implemented the goal-or-refund model with Lemonway escrow, plus shops, checkout, and admin/production pipeline.
