Full Stack AI Developer Required – Node.js, React, PHP, OpenAI & Flutter

@zeeshan5121472

FULL STACK AI Hi, I've got solid experience across this exact stack, Node.js and React.js as my core, PHP for backend work, REST API design and integration, and hands-on OpenAI API integration for AI-driven features. I'm comfortable with database management and understanding existing architecture rather than just bolting on new code, which matters a lot for a long-term project like this where consistency over time counts more than one-off delivery. I work independently, communicate clearly and proactively rather than going quiet between updates, and I'm looking for exactly this kind of ongoing engagement rather than one-off gigs. Happy to start with a smaller task or bug fix first so you can see how I work before committing to the long-term arrangement.

FULL STACK AI I can support your project across React, Node.js/PHP, FastAPI, REST APIs, databases, and OpenAI integrations. I have hands-on experience building AI-enabled applications, RAG/API systems, and maintaining existing full-stack codebases, and I’m available for long-term development. Thanks Anshuman

FULL STACK AI For a long-term project spanning Node.js/PHP backends, React.js, REST APIs, databases, and OpenAI features, I’d focus first on understanding the existing architecture and keeping new development modular rather than adding isolated fixes that become harder to maintain over time. I’m comfortable working across React.js, Node.js, PHP, FastAPI, PostgreSQL/MySQL, REST integrations, OpenAI APIs, and Flutter where mobile work is required. The two priorities would be maintainability and integrations, with clear service boundaries, structured API layers, reliable validation/error handling, and AI functionality separated from core business logic so models or providers can evolve without disrupting the application. I can take ownership of new features, bug fixes, API integrations, database changes, architecture improvements, testing, and ongoing production support. I’m also comfortable joining an established codebase, tracing existing flows, and improving them incrementally rather than pushing unnecessary rewrites. A relevant project is Drona AI, where I worked on an AI-powered product experience combining conversational functionality, structured knowledge, responsive frontend work, and production-focused integration patterns.

FULL STACK AI What stands out is that you’re not looking for someone to work on one isolated layer — you need a developer who can understand the existing architecture and move between PHP/Node.js, React, APIs, databases and AI without creating more technical debt. I can work feature-by-feature across the existing system, first understanding the current backend/API boundaries and then improving or extending them where needed rather than rewriting stable parts unnecessarily. For OpenAI integrations, I prefer keeping the AI layer behind the backend/API so API keys, prompts, validation, usage handling and error cases aren’t scattered through the React or Flutter clients. I can also handle REST API development, database changes, React features, PHP/Node.js work and existing bug fixes as part of the same workflow, with clean code that remains maintainable for the long term. Which part of the current system is the highest priority right now? And is PHP/Node.js split by different modules, or are both used within the same application?

FULL STACK AI I’ve gone through the requirements carefully, and I can take ownership of the ongoing development work across backend, frontend, APIs, AI integrations and existing-system improvements. The long-term nature of the project makes clean architecture and reliable maintenance just as important as adding new features. I can work across Node.js/PHP backends and React.js frontend development, build and maintain REST APIs, handle database operations, and integrate OpenAI-powered functionality into existing or new workflows. For an existing application, I’ll first understand the current architecture and data flow so fixes and new features fit the system rather than introducing disconnected code. I can also handle bug fixing, API integrations, performance improvements and code cleanup as the project evolves. Flutter can be supported where mobile work is required, while keeping the web/backend architecture consistent. I’ll work independently, communicate clearly on progress and keep implementations maintainable for continued development. Share the current application/repository and the first set of tasks, and I can review the architecture and suggest the most practical starting point.

FULL STACK AI Hi, For a long-term project like this, the important part is having one developer who can work across the existing architecture instead of treating Node.js, PHP, React and AI integrations as separate tasks. Webix Infotech can support the full stack with Node.js, PHP, React.js, REST APIs, database management and Flutter. I can work on existing applications as well as new features, including API development, third-party integrations, bug fixing, performance improvements and architecture-level changes. For the AI side, OpenAI API integration can be built into the existing application for features such as intelligent workflows, content generation, structured responses or AI-assisted automation, depending on your product requirements. The implementation would keep API handling, validation, error management and database interactions clean and maintainable. I’m also comfortable reviewing an existing codebase first, identifying architectural issues and then improving it incrementally rather than disrupting working functionality. Since this is intended as ongoing work, consistency and timely delivery would be the focus across each development cycle. Please share the current application and the first feature/task you need handled so I can understand the existing architecture. Best Regards Prachi Webix Infotech
