Juan Valencia

Solutions & Configuration Architect · C#/.NET Engineer · Open-Source Contributor

I build practical software that simplifies complex workflows, improves developer experience, and turns real-world problems into maintainable tools. My work spans .NET applications, browser extensions, data transformation, automated testing, and contributions to established open-source projects.

Open-source contributions

Avalonia UI — Theme accessibility

Improved keyboard-focus visibility in SimpleTheme dark mode · Merged PR #21753

  • Diagnosed a hard-coded focus-indicator color that lost contrast on dark backgrounds.
  • Replaced the static stroke with Avalonia's theme-aware ThemeForegroundBrush.
  • Worked through maintainer review and the project's cross-platform CI process.
  • Merged into main and identified as a candidate for backporting to the 12.1.x release line.

  • Implemented uppercase initials for single- and multi-token person names.
  • Added public API documentation and automated coverage for dictionary and NER-based filtering paths.

Engineering approach

  • Start with the root cause, not the symptom.
  • Prefer focused, maintainable changes with clear validation.
  • Treat review feedback as part of the engineering process.
  • Build tools that reduce friction for both users and developers.

I'm interested in collaborating on .NET tooling, developer productivity, data transformation, and practical open-source improvements.
