About me

I build focused, testable software solutions and short automation tools with clear acceptance criteria. My strongest delivery evidence is a local Python/Excel/CSV reconciliation utility with automated tests. I also handle data cleaning and conversion, JSON/JSONL/CSV utilities, Postman/OpenAPI REST API testing, and reproducible Java/Spring Boot, Vue, or Python fixes after reviewing the project. I prefer bounded 1–3 day milestones with documented inputs, outputs, and acceptance checks. Portfolio items are self-initiated demos using synthetic data, not client projects.

ReconcileKit — Excel/CSV Reconciliation Demo

Self-initiated demo with synthetic Excel/CSV data—not a client project. It matches rows by configurable keys, flags missing, duplicate and mismatched values, and exports a structured Excel report. Includes documented usage and 7 automated tests.
