Senior frontend platform engineer • React • TypeScript • developer experience
Jérémievan der Sande
I build frontend foundations and developer tooling that let product teams develop, test, and ship independently while sharing a coherent platform.
Frontend platforms and developer experience
Shared UI, application architecture, build workflows, and engineering standards determine how quickly and confidently teams can extend a frontend platform as it grows.
My work focuses on the infrastructure behind product delivery: defining frontend architecture, building shared tooling and component systems, clarifying ownership boundaries, and helping teams make consistent technical decisions. I favor practical platform choices that improve maintainability and reduce day-to-day development friction without introducing unnecessary process.

Roles and progression
Over ten years of professional experience spanning frontend implementation, shared platform foundations, developer tooling, and cross-team technical direction.
Ubisoft
Internal cloud-management console and frontend platform
Progressed from Senior Frontend Developer to Technical Lead and Software Architect, working on the foundations of a cloud-management console now developed by about a dozen product teams across three departments.
Software Architect
2023 — Present
Architecture ownership for an ESM-first micro-frontend platform and its shared contracts, foundations, and developer workflows across about a dozen product microapps.
- Evolve an orchestrating shell that assembles versioned product microapps while centralizing authentication, project and scope selection, and privilege elevation.
- Maintain the platform contracts and shared tooling that let product teams develop, test, version, and ship their microapps independently.
- Align product and engineering leads around platform capabilities, maintainable delivery plans, and ownership boundaries across more than 10 teams.
- Run an internal evaluation of AI-assisted development with Claude Code, assessing delivery speed and quality across code, architecture decision records, requirements, and user documentation.
Technical Lead
2021 — 2023
Designed and built the greenfield foundations and reusable tooling that allowed product teams to own and ship microapps within a centralized cloud console.
- Packaged a shared Vite and Vitest configuration used across about a dozen microapps, loading shell context for isolated development and tests while emitting contract-compliant entrypoints.
- Built reusable platform tooling: a shared UI library, a Node.js CLI for microapp bootstrapping and versioned publishing, and a feature-flag stack spanning backend, backoffice, and client library.
- Migrated another React application from Create React App to a shared Vite and Vitest setup.
- Onboarded and supported more than 20 contributors across three departments on platform patterns, component design, code quality, and review practices.
Senior Frontend Developer
2020 — 2021
Joined the cloud-management console at its inception, building React and SASS product flows while helping establish its initial frontend stack and shared implementation patterns.
- Built frontend flows for the console in React and SASS, with Redux-based state management.
- Helped scaffold and maintain the frontend stack shared across the console.
- Improved consistency across product surfaces by extracting reusable components and shared implementation patterns.
Fullstack & Mobile Developer
Nap&Up — maintenance, migration, and v2 delivery for a workplace
wellbeing startup
Took over 2 live production surfaces at Nap&Up, the mobile product and its API, stabilized the existing stack, and led the migration from a Capacitor PWA to a React Native v2 with a new backend on Firebase.
- Stabilized the inherited mobile codebase and production API so the existing product could remain operational throughout the migration.
- Rebuilt the application in React Native and replaced the backend with a fresh Firebase-based implementation.
- Rolled out the new data model, API, and application without disrupting service for more than 500 monthly active users.
AOS
Senior Frontend Engineer
Modernized a large full-stack JavaScript monorepo, improving package boundaries, build configuration, and day-to-day developer workflows.
- Consolidated TypeScript, ESLint, and Webpack configuration from across the codebase into shared foundations.
- Replaced path aliases with proper workspace packages and explicit dependency boundaries, improving the monorepo’s maintainability and scalability.
Fleeters
Urban delivery SaaS for automating last-mile operations
Lead full-stack developer for a B2B SaaS company in urban delivery, shipping across 3 implementation layers, web, backend, and mobile, to automate last-mile operations.
Lead Full-stack Developer
2019 — 2020
Led delivery across the Fleeters product, combining React frontend work, 2 backend stacks in Java and Node.js, and React Native application work in a small team with short feedback loops.
- Led the integration of a dedicated sub-platform for same-day delivery for a major key account.
- Started the migration from a full-JavaScript, CommonJS codebase toward TypeScript and ESM.
- Worked on React Native applications, including custom native modules in Java and Swift, used by 50+ drivers.
Frontend Developer
2018 — 2019
Built and maintained product features across 2 frontend stacks, AngularJS and React, leading refactors that moved key product surfaces from AngularJS to React while also contributing to 2 service stacks, Java and Node.js, for a live B2B SaaS product.
- Delivered product features across 4 operational surface types: dashboards, reporting, settings, and administration, used by dispatch and delivery teams.
- Led refactors that migrated important frontend surfaces from AngularJS to React while keeping the product shipping.
Renesas Electronics
Application Engineer — Advanced Driver Assistance Systems
Support engineer in the Advanced Driver Assistance Systems division, working on computer-vision proof-of-concepts in 2 low-level languages, C and Assembly, and on internal tooling in Node.js and Electron.
- Designed C and Assembly proof-of-concepts for key accounts, working within the memory, latency, and hardware constraints of specialized ADAS hardware.
- Built coding tools and Assembly optimization software in Node.js and Electron to support engineering workflows.
- Direct support contact for a team of 4 external engineers onboarding on specialized computer-vision hardware accelerator.
Open-source tools and experiments
Open-source projects focused on developer experience, designed to make development work clearer, more structured, and more reusable.
Site generator • authoring system
Markee
Markdown • routing • layouts
Site generator for the modern web, built around Markdown authoring, filesystem routing, shared layouts, and an extensible content pipeline.
- Maps directory structure directly to URLs, so documentation, blog content, and site structure stay close to the repo instead of drifting into router configuration.
- Combines build-time Markdown transforms with client-side HTML hydration, plus shared layout slots and extension hooks for custom behavior.
React library • component pipeline
ModularComponent
Typed stages • React • testing
Typed factory pipeline for building React components stage by stage, keeping render, state, lifecycle, and wiring isolated without losing readability.
- Lets capabilities accumulate through ordered stages, with a shared argument map flowing from props and adapters to logic and final render output.
- Supports turning pipelines into hooks, isolating individual stages for tests, and registering stage packs to keep component definitions clean.
Feature flagging • frontend platform
Fuzebox
Bring-your-own backend • White-label backoffice
Frontend-oriented feature flagging solution built around a bring-your-own-backend model, with a white-label backoffice for teams shipping under different brands or product surfaces.
- Keeps storage, auth, and operational concerns compatible with an existing backend instead of forcing teams into a hosted control plane.
- Pairs the flagging layer with a reusable white-label admin surface for managing flags, rollout state, and product-specific workflows.
Technical foundations
A systems-heavy background that still shapes the way frontend problems get approached: through structure, constraints, and what sits underneath the interface.
