Jaksen Charles

Designer becoming a design engineer in NYC, building product interfaces, developer tools, and AI/eval workflows with a strong eye for interaction quality.

I started from product, visual, and interaction design. Now I am deepening the engineering side in public: learning real codebases, shipping small reviewable changes, writing docs and tests, and turning ambiguous workflows into clearer tools.

Current Focus

  • Design engineering: UI systems, interaction quality, and frontend implementation
  • Engineering fundamentals through real open source contributions
  • AI/devtools, agent reliability, evals, and observability workflows
  • Developer experience for complex tools and workflows

Recent Open Source

  • BrowserTrace #239: linked share-safe export guidance across integration docs and added metadata test coverage. Merged May 10, 2026.
  • ZIO Kafka #1692: linked the serialization docs to the existing zio-json serde tutorial.
  • Parameter Golf: compact language-model training experiments and benchmark submissions.

Selected Public Work

  • folio - portfolio site.

How I Contribute

  • A designer's eye for clarity, adoption, and interaction details
  • Small, reviewable pull requests with clear verification notes
  • Documentation and tests that reduce maintainer review burden
  • Follow-up work after maintainer feedback instead of one-off drive-bys
