Developer Workflow Demos

Small practical demos for developer workflow fixes, automation scripts, and browser tools.

This repository is a portfolio for focused freelance work:

• Debugging CI, build, and deployment failures.
• Writing small Python or JavaScript automation scripts.
• Building lightweight Chrome extensions for browser workflows.

Demos

CI Log Analyzer

Location: ci-log-analyzer/

A Python script that reads a CI log and summarizes the likely failure category, evidence, and next steps.

Run it:

cd ci-log-analyzer
python3 analyze_ci_log.py sample-failure.log

CSV Cleaner

Location: csv-cleaner/

A Python script that trims cells, validates email-like fields, removes duplicate rows, and writes clean and rejected output files.

Run it:

cd csv-cleaner
python3 clean_csv.py sample-input.csv --dedupe-key email --out clean.csv --rejects rejects.csv

Chrome Table Exporter

Location: chrome-table-exporter/

A minimal Chrome extension that exports the first HTML table on the current page as CSV.

Install it locally:

1. Open chrome://extensions.
2. Enable Developer mode.
3. Click "Load unpacked".
4. Select the chrome-table-exporter folder.

Deployment Env Checker

Location: deployment-env-checker/

A Python script that checks whether required deployment environment variables are present before a build or deploy step.

Run it:

cd deployment-env-checker
python3 check_env.py required-env.txt sample.env
python3 check_env.py required-env.txt sample-complete.env

Services These Demos Support

These examples map to small, scoped tasks that are easy to verify:

• Fix a failing GitHub Actions workflow.
• Diagnose an npm, Python, Docker, or deployment error.
• Create a small data cleanup script.
• Build a tiny Chrome extension for a repeated browser task.

Work Style

For each task, I aim to provide:

• A short root-cause summary.
• A small patch or script.
• Clear verification steps.
• Notes for anything that requires the client's private environment.
