code-migrator

Fixed-bid code-migration tool. Big-batch migrations (Python 2→3, jQuery→React, AngularJS→Angular, Java 8→17, callbacks→async-await, propTypes→TypeScript) done file-by-file with Qwen.

Pricing model

Bid these as fixed-price gigs on Toptal / Upwork / direct:

• Python 2 → 3: $5-25K per repo (depending on size)
• jQuery → React: $10-50K (per component, expensive)
• AngularJS → Angular: $25-100K
• Java 8 → 17: $5-30K
• propTypes → TS: $3-15K

Qwen does the per-file work; you run tests + ship PRs + handle edge cases. 70-90% gross margin once the workflow is dialed in.

Run

cd C:\openclaw-products\code-migrator
python -m venv .venv
.\.venv\Scripts\activate
pip install -e .

migrate profiles
migrate file --profile py2_to_py3 legacy/foo.py --out new/foo.py
migrate repo --profile py2_to_py3 path/to/repo --limit 10

Workflow for fixed-bid engagements

1. Bid the project (e.g. $15K for a 50K-LOC Py2 codebase).
2. Run migrate repo over the codebase (1-4 hours of inference time).
3. Run the test suite. Triage failures.
4. Send Qwen back through failing modules with the test errors as context.
5. Ship PRs in chunks of 5-20 files each.
6. Final QA + handoff.

Roadmap

• More profiles: Ruby 2 → 3, PHP 7 → 8, Vue 2 → 3
• Test-failure feedback loop (auto-iterate on failures)
• Diff-aware mode (only migrate changed files)
• Per-team style guide enforcement
