n8n Specialist – Automation Workflow with OpenAI GPT-4o Vision API & Supabase DB
Ahsan successfully developed our n8n workflow integrating Fluent Forms, OpenAI GPT-4o Vision, Supabase Storage/PostgreSQL, and WhatsApp/email notifications. He handled structured JSON output, image processing, database integration, error handling, and workflow reliability very professionally. His communication was clear, the solution was well organized, and I would gladly recommend him for n8n, AI automation, OpenAI API, and custom integration projects.
About Ahsan
AI Automation & AI Agent Engineer | n8n, Chatbots, Voice AI,RAG
Lahore, Pakistan - 9:42 am local time
My solutions combine AI engineering, workflow automation, APIs, and reliable software architecture. I work with n8n, OpenAI, Claude, Gemini, LangGraph, LangChain, Python, FastAPI, vector databases, voice AI platforms, CRM systems, and custom business applications.
WHAT I CAN BUILD FOR YOU
• AI agents that use tools, APIs, databases, and business applications
• n8n automation for sales, support, marketing, recruitment, and operations
• AI chatbots for websites, WhatsApp, Slack, Telegram, Discord, and email
• Voice AI receptionists, sales agents, qualification agents, and booking agents
• RAG knowledge assistants for documents, websites, and private company data
• CRM automation for HubSpot, Salesforce, GoHighLevel, Pipedrive, and custom platforms
• AI lead generation, enrichment, scoring, routing, and outreach workflows
• Customer-support automation with ticket creation and human handoff
• Intelligent document processing for invoices, forms, contracts, and reports
• OpenAI, Claude, Gemini, Azure OpenAI, and open-source LLM integrations
• Custom AI SaaS platforms, internal tools, dashboards, and administration portals
• API, webhook, OAuth, database, and third-party application integrations
• Existing workflow audits, troubleshooting, optimisation, and migration
AI AUTOMATION AND n8n
I design reliable workflows using n8n, Make, Zapier, and custom Python or JavaScript services. These workflows can connect CRM platforms, email systems, Google Workspace, Microsoft 365, Slack, WhatsApp, Telegram, calendars, Airtable, Notion, spreadsheets, databases, e-commerce platforms, forms, internal applications, and third-party APIs.
Typical automation projects include lead capture and qualification, personalised outreach, CRM synchronisation, ticket classification, appointment scheduling, recruitment screening, document approvals, e-commerce support, executive reporting, alerts, approvals, and operational notifications.
AI AGENTS AND LLM APPLICATIONS
I build agents that operate within controlled boundaries, retrieve information, select tools, execute authorised actions, and request human approval when necessary. Capabilities can include function calling, multi-step orchestration, agent memory, multi-agent routing, structured JSON output, database access, MCP integrations, model fallback, tracing, and evaluation.
RAG AND KNOWLEDGE ASSISTANTS
I develop retrieval-augmented generation systems that answer from approved business content rather than relying only on general model knowledge. Features can include multi-format ingestion, semantic and hybrid search, vector databases, metadata filters, reranking, citations, confidence thresholds, conversation history, user feedback, administration, and permission-aware retrieval.
VOICE AI AGENTS
I build conversational voice agents for AI reception, lead qualification, appointment booking, customer support, sales follow-up, reminders, call transcription, summarisation, CRM updates, and outcome tracking. I can work with Vapi, Retell AI, Twilio, ElevenLabs, Deepgram, and custom voice infrastructure.
TECHNICAL STACK
AI and LLMs: OpenAI, Claude, Gemini, Azure OpenAI, Llama, Mistral, Hugging Face, embeddings, structured outputs, tool calling, multimodal AI, prompt engineering, fine-tuning, and evaluation.
Agents and RAG: LangGraph, LangChain, LlamaIndex, CrewAI, MCP, vector databases, hybrid retrieval, reranking, metadata filtering, memory, and orchestration.
Automation: n8n, Make, Zapier, webhooks, REST APIs, GraphQL, OAuth, scheduled workflows, custom connectors, CRM integrations, and event-driven systems.
Software Development: Python, FastAPI, Django, Node.js, TypeScript, Next.js, React, PostgreSQL, MongoDB, Redis, Supabase, Docker, background processing, and cloud deployment.
PRODUCTION RELIABILITY
I design for hallucination reduction, prompt-injection protection, data permissions, duplicate-action prevention, structured response validation, retries, API limits, human approval, audit logs, cost control, latency, monitoring, fallback behaviour, secure credential management, and regression evaluation.
MY DELIVERY PROCESS
1. Understand the business objective, users, and existing process
2. Map data, integrations, decisions, and edge cases
3. Design architecture and milestones
4. Build a focused working version
5. Test quality, security, latency, and cost
6. Deploy with documentation and monitoring
7. Continue with optimisation and new features
You can hire me for a small n8n repair, an AI automation audit, a website or messaging chatbot, a voice AI agent, a RAG knowledge assistant, a CRM integration, a proof of concept, a complete AI SaaS product, or long-term AI engineering support.
Send me your existing process, product idea, or technical challenge.
