About Muhammad Usman
GoHighLevel & Voice AI Automation Expert | Vapi, n8n, CRM Workflows
100%
Job Success
Okara, Pakistan - 9:03 am local time
Your team is doing manually what a system could handle. I build the automation that fixes that, and the full-stack product around it when you need one.
I work with 10+ businesses on n8n workflows, GoHighLevel CRM automation, and AI voice agents using Vapi and Retell that connect your tools and remove manual steps from lead capture, follow-up, and reporting.
When the automation needs a real product wrapped around it, I also build that in React, Next.js, and Node.js.
💼 𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝
■ Workflow Automation
n8n, Make, and Zapier multi-step automations connecting CRMs, databases, and internal tools. Lead routing, SMS and email sequences, and reporting that runs itself instead of someone copying numbers into a spreadsheet every week.
■ CRM and Voice Automation
GoHighLevel pipelines, funnels, calendars, and full automation builds. Vapi and Retell voice agents for inbound and outbound calls, lead qualification, and appointment booking.
■ Full Stack Development
React, Next.js, Node.js, Supabase, PostgreSQL. I build this when the automation needs a dashboard, client portal, or SaaS product to sit on top of it, not as a separate, disconnected offering.
■ 𝐀𝐈 𝐀𝐠𝐞𝐧𝐭 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭
✔ Multi-agent workflows using OpenAI, Claude, and LangChain
✔ RAG systems with Pinecone knowledge bases — agents that know your business
✔ AI chatbots for lead qualification, support, and appointment booking
✔ Autonomous routing systems that handle complexity without human input
💡 𝐖𝐡𝐲 𝐂𝐥𝐢𝐞𝐧𝐭𝐬 𝐂𝐨𝐦𝐞 𝐁𝐚𝐜𝐤
I do not build something and disappear. Whether it is a React dashboard or an n8n workflow, I build it to hold up under real conditions, document everything so your team can operate it independently, and stay available when the business grows and needs something new.
If that is where you are, message me, and I will tell you exactly how I would make your life easy.
