Highlights

• Software Engineer at Fabric

  • Built and shipped a production spatial exploration feature used to navigate large information spaces within the Fabric platform.
  • Designed frontend architecture combining standard web UI with high‑performance canvas rendering under strict interaction constraints.
  • Implemented canvas layout and coordinate systems, increasing practical capacity from hundreds to thousands of nodes.
  • Optimised rendering and input handling to maintain consistently responsive panning, zooming, and selection across dense interfaces.

• Software Engineer at Journal

  • Maintained and evolved a production web application for organizing, writing, and sharing personal knowledge.
  • Integrated and developed client tooling to manage core state and caching logic, reducing UI glitches and improving reliability through structured tests.
  • Shipped reusable UI layout libraries supporting lists, grids, masonry layouts, and document‑driven workflows.
  • Implemented and refined the core design system in close collaboration with product design leadership.
  • Partnered cross‑functionally with design and product to deliver user‑facing features from concept through production.

• Software Engineer at Nette

  • Built advanced web‑based editor interfaces with custom selection, annotation, and cursor‑driven interaction models.
  • Tuned frontend state systems to reduce latency in key data‑insight workflows and improve interaction responsiveness.
  • Integrated editor SDKs and external APIs to support multiple content types and extensible workflows.
  • Contributed to frontend architecture decisions improving scalability, maintainability, and long‑term product evolution.

• Software Engineer at Status

  • Delivered user‑facing features within a large, design‑led mobile and web product organization.
  • Collaborated across engineering and design to explore and define critical messaging infrastructure under performance and privacy requirements.
  • Contributed to shared application logic supporting multiple client platforms and surfaces.
  • Helped deliver stable, privacy‑conscious user experiences within a large‑scale production environment.

Education

• MA Virtual Reality at Goldsmiths, University of London
