Contributed to the OpenRakis/Spice86 project by developing a native DOS API emulation testing suite and enhancing command-line interface reliability. Leveraging Assembly, C, and C#, implemented native DOS test programs and scripts to improve regression testing and emulator verification. Refactored CLI parsing to support multiple numeric formats, strengthened input validation, and resolved encoding issues, resulting in more robust cross-platform compatibility. Introduced comprehensive unit tests and addressed static analysis warnings to ensure code quality and maintainability. The work enabled repeatable, CI-ready testing workflows and broadened automation capabilities, demonstrating a methodical approach to software development, refactoring, and command-line interface engineering.

Dec 1, 2025December 2025 — Delivered a major Command-Line Argument Handling Enhancement for OpenRakis/Spice86 to boost DOS compatibility. Refactored CLI parsing, improved encoding handling, added input validation, and modernized C# syntax. Implemented a robust test suite to validate command-line processing and CLI behavior. Resolved PSP command-line encoding issues as part of this effort, resulting in a more reliable, cross-environment CLI surface and reduced risk of regressions.

Apr 1, 2025April 2025 (2025-04): Implemented a native DOS API emulation testing suite for Spice86, drastically improving verification of partially implemented DOS APIs and demonstrations of program execution and TSR behavior. Delivered a curated set of native DOS test examples (assembler and C) plus supporting programs and scripts (build, clean, hello, exec, c_exec, tsr) to enable repeatable testing and CI readiness. The work provides a concrete baseline for regression testing, accelerates API stabilization, and strengthens overall emulator reliability.
