Work History

October 2025

19 Commits • 5 Features

Oct 1, 2025

October 2025 focused on delivering measurable business value through reliability improvements, validation simplification, documentation accessibility, and streamlined CI/CD. Key features delivered include adding a dedicated '/documentation' route for Getting Started and migrating validation to Blazor's built-in DataAnnotationsValidator with IValidatableObject. Major bugs fixed include HxAutosuggest chips rendering reliability and HxGrid stability improvements (robust state comparison and onkeyup-based inline editing). CI/build hygiene improvements and release readiness were implemented with a net10 build pipeline, test reference cleanup, cancellation handling, and aligned dependencies across components (Release 4.15.2-pre and 4.16.0). These efforts reduce defect risk, accelerate release cadence, and improve maintainability and documentation accessibility across the product.

Sep 1, 2025

September 2025 focused on stabilizing and modernizing dependencies, fixing critical UI bugs, and strengthening documentation. In havit/Havit.Blazor, I delivered extensive dependency upgrades to the latest stable versions, aligning ComponentsPackages/build properties for consistent versioning, and released multiple versions (4.14.0, 4.14.1, 4.15.0 with ECharts 1.2.0, and 4.15.1) to address security patches and compatibility. In parallel, I fixed a chart options state bug by ensuring notMerge: true overwrites previous options, preventing merged states. I also added UX improvements to numeric input with SmartPaste and SmartKeyboard default-enabled in HxInputNumber. In dotnet/AspNetCore.Docs, I updated trimming behavior documentation for custom types to better reflect default non-trimming and ensure JSON deserialization correctness after publish. Lastly, I completed code quality and reliability efforts, including dead code removal in HxSearchBox, Linux build fix (XmlDoc folder casing), and stylecop integration.
