A Polars-based anonymization library built for ETL workflows that need explicit rules, fast transformations, and reviewable privacy behavior.
- Rule-oriented masking for sensitive operational datasets.
- Polars-first transformations for fast local and pipeline execution.
- Designed as reusable tooling for ETL, notebooks, and validation flows.

Filemindr
A Python CLI for local file automation with watch mode and rule-based organization.
Problem
Local folders drift into manual cleanup and repeated file handling.
Decision
A rule-driven CLI keeps organization transparent and scriptable.
Outcome
A practical automation tool for recurring local workflows.
CloakData
A Polars-based anonymization library for privacy-first ETL workflows.
Problem
Sensitive fields often enter pipelines as one-off masking scripts.
Decision
Rules stay explicit, reviewable, and built around Polars transformations.
Outcome
Reusable privacy tooling for ETL, notebooks, and validation flows.
Editorial
CodeCraftPython Blog
Technical writing on Python, Polars, data engineering, and practical tooling.
Problem
Good engineering decisions are easier to trust when the reasoning is public.
Decision
Articles focus on practical Python, data workflows, and trade-offs.
Outcome
A technical writing channel that supports the portfolio's data focus.
TabuLynx
A Python tool created to inspect tabular data more clearly on Ubuntu workflows.
Problem
Inspecting tabular files locally can be slow, noisy, and context-switch heavy.
Decision
A focused Python interface keeps table review close to the workflow.
Outcome
Clearer local inspection for data-heavy Ubuntu routines.
