FAQ
What languages/frameworks do you review?
Primary: Python (FastAPI, Django, Flask), JavaScript/TypeScript (React, Node.js), SQL (PostgreSQL, MySQL). I can also review Docker, API design, and database schemas. Message me if unsure!
Do you fix the code or just review it?
I provide a detailed review with specific recommendations and code examples. Fixing the code is a separate service (message me for a quote). Premium package includes a 30-min call to discuss fixes.
How detailed is your review?
Very detailed. I provide line-by-line comments for critical issues, security checklists, severity ratings, and concrete fix recommendations. See my YAPXAT review example (link in portfolio).
Can you review proprietary/confidential code?
Yes, I sign NDAs if needed. Your code is never shared or stored beyond the review period.
What if I need a review urgently?
I offer 24-hour express delivery for an extra fee. Message me before ordering to confirm availability.
Do you provide ongoing code review services?
Yes! For teams needing regular reviews, I offer monthly retainer packages. Message me for custom pricing.
