Custom Python 3.10+ scripts: data pipelines, file/format converters (JSON/CSV/XML), API clients, web scrapers, CLI tools with argparse. You get clean, typed, documented code with a README and pytest tests, plus clear usage and edge-case handling. Send the input + the result you want.

I turn your endpoints, route code, or Postman collection into clean OpenAPI 3.0 YAML (typed request/response schemas, reusable refs, example payloads, full error responses) plus a rendered Markdown version generated from the same spec so they never drift. Linted with Spectral so it imports cleanly into Swagger UI/Redoc.

Messy CSV/JSON cleaned, reshaped, deduped, validated, or converted between formats. Regex extraction, schema normalization, one-off scripts you can re-run. Send the data + the target shape.

Clear developer-facing docs from your code or notes: README that converts, API reference, runbook, or a tight cheat sheet. Accurate, skimmable, copy-paste-ready examples.

Send a failing snippet, stack trace, or flaky test. I find the root cause (not a guess), explain why it fails, and give you the corrected code plus how to verify it. Fast turnaround.

Senior-level review of your PR or file: real bugs, security vulnerabilities (injection, auth/IDOR, secrets), performance, and clear fix suggestions with line references. Python, TypeScript, JavaScript, Go, Rust, SQL, Bash. You get a structured written report, not vague notes.
