Message

At KPMG, I engineered a tax reporting system with 400+ business rules, automated validation workflows, and parallel computation. I also designed pipelines for XML validation and financial reporting, with automated tests to catch errors early.

At P4D, I developed production applications for automated workflows, data processing, verification, and structured validation. I investigated system behavior through application outputs, logs, and data flows, and contributed to solutions that reduced manual validation.

In freelance work, I developed Python and CLI tools for data validation and inconsistency detection. At NextPractice, I contributed to modernizing AI-enabled workflows by refactoring a legacy React codebase into a structured TypeScript architecture.
