I am looking for a highly skilled PHP developer with strong experience in AI/LLM integration to build a complex web-based platform. This is not a simple chatbot or API wrapper project. The goal is to create a production-ready AI workflow system in PHP that can handle multi-step task execution, document analysis, tool calling, workflow management, and secure AI-driven automation. Scope of Work: The selected freelancer will design and develop a PHP-based application, preferably using Laravel or Symfony, with clean architecture, scalability, and strong security practices. The system should allow users to submit tasks that are processed through multiple AI-driven stages such as planning, analysis, retrieval, validation, and reporting. The platform should support: - Multi-step AI workflows - Role-based AI agents (planner, analyst, reviewer, summarizer, etc.) - Secure tool/function calling - Document upload and retrieval-based AI responses - Execution logs and workflow history - Human approval checkpoints for sensitive actions - Error handling, retries, and resumable processing Technical Requirements: The backend must be built in **modern PHP** with a structured and maintainable codebase. Preferred stack includes: - PHP 8+ - Laravel or Symfony - PostgreSQL or MySQL - Redis for queues/cache - Dockerized setup - Integration with OpenAI or similar LLM APIs - Vector database or pgvector support for document retrieval The solution should include: 1. Workflow Engine A configurable engine to define and execute multi-step AI workflows. 2. AI Agent Orchestration Support for multiple AI roles with different prompts, permissions, and output rules. 3. Tool Execution Layer Safe execution of approved internal or external functions requested by the AI. 4. Document Processing / RAG Upload, parse, chunk, embed, and retrieve information from files such as PDF, DOCX, TXT, and HTML. 5. Observability Full logging of workflow steps, AI responses, tool calls, failures, retries, and costs. 6. Security Input validation, role-based permissions, prompt injection protection, secure API key handling, and audit logs. Deliverables: The freelancer must provide: - Full source code - Database schema and migrations - API documentation - Docker setup - Sample workflows - Test suite - Deployment guide - Technical architecture documentation Important Notes: This is a high-difficulty project intended for experienced developers only. Please do not apply if your background is limited to basic chatbot development or simple API integrations. I am specifically looking for someone who can build a secure, scalable, and production-grade AI platform in PHP.

Hello, I’m a senior PHP developer with strong experience building secure, production-grade web applications and integrating AI/LLM workflows into real business systems. Your project stands out because it requires more than a simple chatbot. It needs solid architecture, workflow orchestration, security, and scalability. I can build this platform using PHP 8+ with Laravel or Symfony, following clean architecture principles for long-term maintainability and extensibility. My experience includes multi-step workflow systems, Redis-based queues, secure API integrations, document pipelines, audit logging, RBAC, and AI orchestration. For your solution, I would design a configurable workflow engine, modular AI agents with clear responsibilities, a secure tool execution layer, and a document processing pipeline with vector search support using pgvector or a similar database. I would also include execution logs, cost tracking, failure recovery, and strong operational visibility. I can deliver complete source code, migrations, Docker setup, API documentation, sample workflows, automated tests, deployment instructions, and architecture documentation. My focus is always on robust, secure, and production-ready systems, not quick prototypes. With 10+ years of experience in PHP, Docker, JavaScript, MySQL, and OAuth, I bring both technical depth and practical engineering judgment. I’d be glad to discuss your requirements and the best architecture for this platform. Best regards

Hi, As an experienced PHP developer who has spent years specializing in the full-stack development, I am confident that I am well-equipped to deliver on every aspect of your project. Having worked with PHP for over a decade, building robust applications using Laravel and Symfony is second nature to me. Furthermore, I possess the ability to design and execute complex AI integrations, as your platform demands, utilizing APIs such as OpenAI or similar. In terms of document-processing capabilities, I am well-versed in handling various file formats like PDFs, DOCXs, TXTs, and HTMLs. This means that your web-based platform can not only receive and retrieve these documents but also extract meaningful information from them in a way that aligns with the specifics of this task. Security has never been more important than it is today. In my previous projects on AI integration tasks, I have incorporated robust security measures inclusive of prompt injection protection, secure API key handling, extensive input validation among others. It is my commitment to not just develop the AI system but to ensure it functions safely and reliably within your business environment. To enhance maintainability and deployment flexibility, I will utilize modern PHP - version 8+ - along with Laravel or Symfony frameworks for smooth integration with PostgreSQL or MySQL databases. The final application will be put through rigorous testing to ensure its reliabili Thanks!

Hi! You’re not asking for a chatbot, you need a Laravel or Symfony workflow engine that runs multi step jobs with queues, logs every stage, supports agent roles, safe tool calling with approvals, and RAG with embeddings plus a vector store like pgvector. I can build this with PHP 8, Redis queues, Docker, and a strict tool execution layer that only runs whitelisted functions, with retries and resumable runs. I’m Edward, 10+ years in PHP since 2014. Can we chat about your first 2 sample workflows and the tool list?
