Ashley Cook
Frontend Engineer
I build React and TypeScript applications with a focus on interactive, high-performance user interfaces. My experience spans product development, frontend architecture, Canvas and WebGL applications, and migrating complex legacy systems to the web.
I've worked on browser-based editors, enterprise diagramming tools, browser games and interactive web applications. Many of these products managed large datasets, complex interactions or long-lived customer data, requiring frontend architecture that remained responsive as products evolved.

Brief About
Building large interactive applications
Most of my work has involved products where the frontend is the application rather than a thin layer over an API. Diagram editors, migration tooling and browser-based software all place long-term demands on application structure.
That has led to work on component architecture, migration tooling, editor-style interfaces and frontend performance, where maintaining existing behaviour is often as important as delivering new features.
Expertise
Where frontend work meets rendering constraints
Frontend Engineering
Building React applications that remain understandable as products, teams and requirements grow.
Rendering Systems
Building Canvas-based interaction systems that support complex React applications and large visual datasets.
Graphics & Web Technologies
Interactive Interfaces with PixiJS, WebGL and modern graphics APIs to solve practical product problems.
Enterprise Applications
Developing internal tools and customer-facing products where years of existing behaviour can't simply be rewritten.
Migration & Legacy Modernisation
Moving established products onto modern foundations without disrupting the people already using them.
Product Development
Turning vague ideas into software by identifying the technical constraint that actually shapes the solution.
Featured Work
Projects with real implementation constraints
Different products, but the same engineering mindset. Each project involved building software where rendering performance, interaction design and long-term maintainability couldn't be treated as separate concerns.
