React Node.js Developer Needed for CRM Enhancement

@Tacticssoft

Hi, I have solid experience enhancing and maintaining live SaaS and CRM platforms built with React and Node.js. I’m comfortable working inside production codebases where stability, performance, and clean structure are critical. I’ve worked on CRM-style systems involving lead management, workflow automation, role-based access, and third-party integrations. My focus is always on extending functionality without breaking existing flows. On the frontend, I optimize React components for performance, usability, and maintainability. I ensure clean state management, reusable components, and responsive UI behavior. On the backend, I build and extend REST APIs using Node.js (Express/Fastify), improve validation layers, optimize database queries, and ensure secure, efficient data handling. I have experience working with MongoDB and MySQL, including indexing, query optimization, and schema refinement for scalability. I follow structured Git workflows with clean commits, feature branches, and proper code reviews where needed. I’m comfortable implementing third-party API integrations and improving overall system reliability. Availability: 25–35 hours per week I’m open to ongoing collaboration and regular progress updates. Looking forward to helping you enhance and scale your CRM platform efficiently.

Hi there, I am a strong fit because I have extended live React and Node.js CRM systems without disrupting active users. I have worked on production SaaS platforms where I enhanced modules, optimized React components for performance, and refactored Node.js APIs for better validation and response times. I am comfortable improving database queries in MongoDB or MySQL, implementing third-party integrations, and maintaining clean Git workflows with structured commits and reviews. I have also handled staged deployments to ensure new features do not impact existing workflows. I reduce risk by first auditing the current architecture, identifying bottlenecks, and prioritizing changes that improve performance and reliability before layering in new functionality. All enhancements are developed in controlled branches with testing and rollback plans to protect the live environment. I am available for ongoing contract work and can provide consistent progress updates while taking ownership of feature delivery and system stability. Regards, Chirag
