Freelance Developer for Code Review & Optimization

@salmanshahid5432

Hi there, You need a codebase and DB review with optimizations, security checks, and Razorpay/UPI integration—sounds like a solid Django + React audit project. One mistake I’ve seen is leaving SQLite configs hanging in prod-ready code—it causes silent bottlenecks. The fix is proper Postgres migrations with indexing and query analysis. Quick tech question: do you want the review delivered as a detailed written report only, or should I also patch the top-priority issues directly in the repo? I’m finishing up another Django/React audit this week and can take yours right after—let me know if you’d like me to start. Best, Salman Shahid

Hello, I can make your website faster, safer, and ready for growth. Your users will notice the difference immediately. I understand you want clean, secure, and scalable code. I recently improved a Django site, fixing database queries and security issues. This cut load time by 60 percent and made the site safer for users. I can do the same for your project. I will review your code for clarity and modularity, check the database for performance, and fix security issues like SQL injection, XSS, and authentication problems. I will also suggest improvements for speed and scalability. For payments, I will integrate UPI and Razorpay so users can pay easily. I will provide a detailed report with issues and actionable steps. Optional fixes can follow if needed. I recommend Django 5 and PostgreSQL for a secure, fast backend, with React and Tailwind CSS for a smooth frontend. Do you have design samples or inspiration? We can have a quick 15-minute call to align on your vision and plan the steps.
