@SEOGlobalLLC

Hi there, thanks for sharing the details of your project. We understand you need an experienced developer to audit, debug, and stabilize an existing NestJS backend with PostgreSQL and Redis, while fixing React Native app issues and ensuring smooth, reliable API communication for a production-ready release. SEO Global Team has strong hands-on experience working with NestJS, PostgreSQL, Redis caching and queues, and React Native, particularly in refactoring legacy codebases, resolving performance bottlenecks, and fixing complex backend–mobile integration issues. Our approach is to thoroughly review the current codebase, identify and resolve bugs and architectural gaps, optimize database and Redis usage, harden API responses, and methodically stabilize the React Native app with clean, maintainable improvements. Do you have the codebase in a Git repository we can review immediately? Are there specific critical bugs or crashes that must be prioritized first? Is Redis currently used mainly for caching, queues, or both? Looking forward to helping you get this project stable and production-ready.

@aceman23

Hi, I am Anton from Irvine, CA. I've reviewed your Refine NestJS + PostgreSQL + Redis + React requirement and have extensive experience optimizing full-stack applications with this exact tech stack. I specialize in performance tuning, architecture improvements, and code refinement for production-ready systems. I'll refine your application stack by optimizing NestJS backend with improved module structure, dependency injection best practices, and efficient middleware configuration, tuning PostgreSQL queries with proper indexing and query optimization, implementing Redis caching strategies for frequently accessed data and session management, optimizing React frontend with performance improvements (memoization, code splitting, lazy loading), and ensuring seamless integration between all layers. I'll address bottlenecks, reduce response times, improve scalability, and enhance code maintainability. Questions: 1. What specific issues need addressing (slow API responses, database bottlenecks, caching inefficiencies, frontend performance, code quality concerns), and do you have performance metrics or monitoring data? 2. What's the application's current scale and expected growth (users, data volume, request load), and do you have existing test coverage or need testing infrastructure added? Ready to refine your stack as soon as you provide codebase access and outline priority optimization areas. Best, Anton

@andersonc32

I have reviewed your existing project built with NestJS, PostgreSQL, Redis, and React Native. Since this is an already developed system with bugs and stability issues, I propose working on an hourly basis, focusing first on critical errors and then on structural improvements. I will start with a technical audit of the NestJS backend to identify logical issues, architectural weaknesses, and performance bottlenecks. Then I will optimize PostgreSQL queries, review and improve Redis usage (cache/queues/sessions), fix API inconsistencies, and standardize response handling. I will also review the React Native application to ensure stable and efficient communication with the backend. I have solid experience working with legacy code, applying progressive refactoring while prioritizing stability and performance. Hourly rate: USD 25 Initial estimate: 5–15 hours depending on the current state of the project. After an initial review, I can provide a more precise time estimate.
