About Hashir

Hashir W.Status: Offline
AI Agents and Workflow Automation | n8n, Make, Zapier
Karachi, Pakistan - 5:52 pm local time
I build AI-powered systems that replace repetitive manual work — so your team focuses on the work that actually grows your business.

Whether you need an AI agent that qualifies leads 24/7, a voice bot that books appointments on autopilot, or an end-to-end workflow that connects your CRM, helpdesk, and databases — I design, build, and document it from scratch.

🔁 WORKFLOW AUTOMATION & SYSTEM INTEGRATION
Connecting your tools and eliminating manual handoffs using Make, n8n, Zapier, and Gumloop. Custom APIs built in FastAPI, Node.js, and Python. Vector search and RAG pipelines with Pinecone. CRM sync with HubSpot, Salesforce, Zoho, and GHL.

🤖 AI AGENTS & AGENTIC WORKFLOWS
Autonomous agents for lead qualification, customer onboarding, report generation, and document processing. Multi-agent orchestration with LangChain, LangGraph, and CrewAI. Real-time context retrieval from your CRM, databases, and internal tools.

🎙️ VOICEBOTS & VOICE AI
Inbound and outbound automated phone calls for booking, follow-ups, and sales — built on Retell AI, Vapi, Twilio, SynthFlow, and ElevenLabs. Auto-synced with Calendly, Google Calendar, and your CRM so zero human intervention is required.

💬 AI CHATBOTS & CUSTOM GPTs
Website and portal chatbots for instant query handling, lead capture, and internal comms. Powered by GPT-4o with fine-tuning and LangChain integrations for real-time data pulling and email drafting.

🏭 INDUSTRY EXPERIENCE
Real estate, e-commerce, healthcare, construction, professional services, and SaaS. I've built automations for lead scoring, EHR extraction, cart abandonment recovery, supply chain monitoring, and contract automation.

✅ WHY CLIENTS HIRE ME AGAIN
• I start every project with a discovery call — no guessing what you actually need
• I document everything so your team can maintain it independently
• Fully white-label ready — resellers welcome
• 40–48 hrs/week availability with fast, proactive communication
• Delivery on time, on spec, every time

Ready to automate? Send me a message and let's map out what your system should look like.
