Senior Frontend Engineer — Lead

Marketplace platform for entertainment, recreation, dining & tourism vendors

• React
• TypeScript
• Vite
• shadcn/ui
• Feature-sliced architecture
• REST
• SignalR
• Google Maps API

• Sole frontend engineer on the Hobber vendor platform — the frontend is mine end to end, architected from an empty repository in React and TypeScript on a modular, feature-sliced structure.
• Shipped seven core platform modules — authentication, vendor accounts, dashboards, scheduling, payouts, integrations, and team access — as independent slices over one shared component layer built on shadcn/ui and Radix primitives.
• Built the vendor workflows on top: activity management, booking flows, stock scheduling, discount logic, and content management.
• Set the architectural boundaries the codebase is held to, so a new domain is a new folder rather than a refactor — cross-slice imports blocked by a lint rule rather than a convention, and the contracts type-checked where slices compose.
• Set up the testing layer from scratch — Vitest for unit and integration, Playwright for end-to-end across the vendor workflows.
• Built real-time vendor messaging on SignalR against the .NET backend, and the location and routing surfaces on the Google Maps API.
• Partner with backend and DevOps engineers on API contracts — pinned against Swagger before building — authentication systems, and platform features.

Senior Frontend Engineer — Lead

Enterprise media technology delivered on the Mosaic platform

• React
• Next.js
• TypeScript
• GraphQL
• SCSS
• Shaka Player / DRM
• Zustand
• React Hook Form
• Zod
• Azure Blob Storage
• i18n
• Azure DevOps

• Led the frontend team building high-performance web applications for clients including the Goethe-Institut and the Lindau Nobel Laureate Meetings, delivering two client products 0→1 — the Goethe-Institut and Lindau builds — through full development, testing and production release cycles.
• Reduced page load time ~15% through bundle optimization, lazy loading, and caching improvements.
• Built on Axinom's Mosaic micro-frontends (Media, Catalogue, Entitlement, DRM) and its APIs for content synchronization and metadata management, rather than hand-rolling media delivery.
• Implemented secure DRM playback with Shaka Player, building the player interface as our own event-driven components on top of its defaults rather than inheriting browser-native controls and caption rendering — which look and behave differently on every engine.
• Held playback and layout across a browser matrix spanning Chrome, Edge, Firefox and Safari on macOS, Windows, iOS, iPadOS and Android — including that every iOS browser is WebKit underneath, so a defect reported against iOS Chrome is a Safari defect.
• Designed i18n in from the start for multi-language experiences across regions.
• Delivered large media assets out of Azure Blob Storage through the Azure SDK for the Goethe-Institut build — files big enough that the browser could not simply hold one, so the transfer had to be handled rather than requested.
• Worked directly with designers to translate Figma into pixel-perfect, responsive interfaces, holding SEO and WCAG-aligned accessibility across every customer-facing surface.
• Owned client-facing technical communication — requirements, feasibility, UX trade-offs, and scope — mentored junior engineers, enforced coding standards, and kept CI/CD stable with DevOps across environments.

Senior Frontend Engineer

Enterprise CMS for service management and logistics

• React
• TypeScript
• Storybook
• Cypress
• Redux
• Zustand
• TanStack Query
• React Hook Form
• MUI X Data Grid
• Node.js / Express
• Sequelize
• MySQL
• Atomic Design
• AWS

• Architected and delivered a React CMS from 0→1 to MVP as domain modules with SOLID boundaries — each feature owning its components, state and API access, depending only on the shared UI layer beneath it — then led 40+ production releases on it.
• Migrated a legacy Laravel, jQuery and Bootstrap application to React and ExpressJS incrementally without freezing client delivery — I had worked in that codebase before replacing it, which is why the seams were obvious — and built Node.js BFF layers with the backend team to reduce API latency.
• Introduced test-driven development with Jest and Cypress end-to-end gates, driving overall automated coverage to ~90% with every critical path behind the merge gate in CI/CD — which is what let releases stay frequent without a regression freeze.
• Built a Storybook-based reusable component library that cut frontend development time ~30% across projects.
• Reduced page load time ~40% through code-splitting, lazy loading, and asset optimization, with assets served from AWS S3.
• Built REST integrations against the client's enterprise vendor stack — Amtek (Australia), running on Fiserv, Toshiba, NTT DATA, Park Assist and City systems — across a 250+ table schema.
• Translated Figma designs into responsive interfaces; set frontend standards and ran code reviews as the company scaled from 10 to 60+ people.

Frontend Engineer

Seed-stage startup — internal systems and web products

• React.js
• JavaScript
• SCSS
• Agile / Scrum

• Joined as a Frontend Engineer Intern in December 2018 and moved into the full role in June 2019 — first end-to-end UI ownership at a seed-stage startup.
• Delivered an Employment Management System from concept to production as the end-to-end UI owner, in React.js, JavaScript, HTML, and SCSS.
• Rebuilt the company website around responsive layout and accessibility, lifting UX and conversion ~15%.
• Improved application performance through refactoring and component-level optimization, and ran code reviews and pair-programming sessions to keep the codebase maintainable as it grew.
