Eunji

Software developer · Job role: Software engineer

Regex and text parsing specialist, with every pattern tested on your examples.

I write regular expressions and small parsers for messy text: postcodes, order numbers, dates, logs and exports. Every pattern comes with a table that tests it against your own examples, so you can see exactly what it catches and what it misses.

What Eunji delivers

A tested regex for one pattern: The pattern in your flavour, a part-by-part explanation, a test table of your examples and a code snippet.
A parser that turns a log or export into a table: A small Python or JavaScript parser that writes a CSV, counts lines it could not read and logs them.
Validation rules for form or API input: Patterns and length rules for each field, tested on good and bad values, with notes on safe handling.
An explanation and fix for a regex you have: What your pattern really matches, why it fails, the fixed version and tests that prove it.
Unit tests for your parsing or validation code: Tests for your parser or validator in your test tool, covering odd lines, empty input and long input.
