Job Success
Okara, Pakistan - 5:30 am local time
My goal is not to give you another complicated workflow that looks impressive but creates little business value.
𝐇𝐨𝐰 𝐈 𝐜𝐚𝐧 𝐚𝐮𝐭𝐨𝐦𝐚𝐭𝐞 𝐲𝐨𝐮𝐫 𝐛𝐮𝐬𝐢𝐧𝐞𝐬𝐬:
⚙️n8n, Make, and Zapier Automation
I build reliable n8n, Make, and Zapier workflows that reduce manual work across lead capture, CRM updates, onboarding, follow-up, reporting, and daily operations.
My experience includes 300+ n8n workflows and 500+ Zapier workflows using filters, routers, Paths, APIs, webhooks, custom logic, monitoring, and error handling.
🤖 AI Agent Development
I develop AI agents using OpenAI, ChatGPT, Claude, LangChain, and custom APIs.
These AI agents can:
• qualify and route leads
• answer customer questions
• search documents and business data
• update CRM records
• create tasks and follow-ups
• process documents
• support sales and internal operations
• transfer complex requests to a human
Unlike basic chatbots, these agents connect with live business systems and take useful actions automatically.
🎙️ Vapi, Retell AI, and Voice AI
I build inbound and outbound Voice AI agents for:
• cold calling and lead follow-up
• lead qualification
• appointment booking
• customer support
• reminders and confirmations
• missed-call recovery
• human call transfer
• 24/7 call handling
I connect Vapi and Retell AI with n8n, Make, CRMs, calendars, ElevenLabs, Twilio, and custom APIs.
The system can generate transcripts and call summaries, update lead records, trigger follow-up workflows, handle voicemail, retry failed calls, and notify your team when human action is needed.
📈 CRM, Sales, and Lead Automation
I build conversion-focused CRM automation for:
• lead capture and enrichment
• lead scoring and qualification
• automatic routing and assignment
• pipeline updates
• email and SMS follow-up
• appointment scheduling
• missed-lead recovery
• customer onboarding
• sales reporting
The goal is simple: every lead receives the right response at the right time.
🔗 API and System Integrations
I connect CRMs, forms, calendars, email platforms, databases, Airtable, Google Sheets, AI models, and custom applications using REST APIs, webhooks, and real-time data flows.
When standard automation tools are not enough, I can also build lightweight full-stack dashboards, admin panels, customer portals, custom forms, and automation control interfaces.
You will receive a tested and maintainable AI automation system designed to reduce manual work, improve response speed, and support real business growth.
𝐒𝐞𝐧𝐝 𝐦𝐞 𝐲𝐨𝐮𝐫 𝐜𝐮𝐫𝐫𝐞𝐧𝐭 𝐩𝐫𝐨𝐜𝐞𝐬𝐬, 𝐭𝐡𝐞 𝐭𝐨𝐨𝐥𝐬 𝐲𝐨𝐮 𝐮𝐬𝐞, 𝐚𝐧𝐝 𝐭𝐡𝐞 𝐦𝐚𝐧𝐮𝐚𝐥 𝐬𝐭𝐞𝐩𝐬 𝐬𝐥𝐨𝐰𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐛𝐮𝐬𝐢𝐧𝐞𝐬𝐬 𝐝𝐨𝐰𝐧.
I will identify the best automation opportunities and recommend the right solution using n8n, Make com, Zapier, Vapi, Retell AI, AI agents, or custom API integrations.
