Meet candidatesWhat excellent frontend development looks like
Frontend has long been more than buttons and forms. Modern web applications carry a large share of business logic, data processing and user experience. A senior frontend developer therefore owns not just individual components but the architecture of the whole application: how it is structured, how data flows, how fast it loads and whether everyone can use it.
Excellence rarely shows in a single feature – it shows over time: in a codebase that can still be extended cleanly after years, in teams that deliver in parallel without slowing each other down, and in interfaces that stay smooth even with large datasets.
How to recognize a senior frontend developer
Thinks in architecture, not pages
Structures applications so they can grow – with Nx monorepos, clear module boundaries or microfrontends via Module Federation.
Builds systems, not parts
Develops design systems and UI libraries that ensure consistency and take work off every new feature.
Keeps interfaces fast
Knows the levers for load time, bundle size and rendering – even for dashboards with real-time data.
Makes accessibility the default
Plans keyboard navigation, screen reader support and semantic markup from the start instead of retrofitting them at the end.
Masters data flows
Uses state management with RxJS, NgRx, Signals or Redux confidently and actively shapes backend APIs, for example as a GraphQL BFF.
Moves the whole team forward
Establishes guidelines, tests and code reviews, guides modernizations and shares knowledge with other developers.
When good frontend is no longer enough
Many frontends start fast and solid – and become heavier with every release. Components grow unchecked, shared standards are missing, and small changes cause unexpected bugs. Dashboards with large datasets feel sluggish, load times climb, and accessibility requirements keep getting postponed until they become a risk.
At the latest when several teams work in the same application, a legacy interface needs modernizing or a new product should be set up right from day one, developer experience decides the outcome. That's when you don't need more capacity – you need someone who lastingly improves the quality of your frontend.
