• 🎯 Open to Software Engineer / SDE-1 opportunities

I contribute bug fixes, validation improvements, regression tests, and reliability fixes to production open source projects.

Command Palette · C# / .NET

Fixed bookmark placeholder values remaining cached between launches.

• Cleared cached placeholder values after successful command execution
• Preserved values when launch fails
• Added regression coverage through the actual command invocation path
• Iterated on tests and CI based on maintainer review
• Merged into microsoft/PowerToys:main

Java · Validation · Backend

Contributed multiple fixes across Kestra's core backend.

• Fixed KPI LABELS validation when a required label key is missing
• Added save-time validation for typed static flow output values
• Fixed recursive matching for dotfiles such as .env and .gitignore
• Added regression tests for each affected path

PR #19629 · PR #19529 · PR #19153

Observability · Validation

Fixed date/time paste validation so semantically invalid calendar and clock values are rejected instead of being accepted by supported absolute date/time formats.
