If you’re looking to remove bottlenecks, scale client interactions, and turn your operations into a well-oiled, AI-powered machine, you’re in the right place. I don’t just integrate AI tools, I'll transform your business into an AI-powered organization.
⭐⭐⭐⭐⭐“Working with Haroon has been one of the best decisions I’ve made for my business.” - Tania B. (Kube Coworking)
-------------------------------------------------------
Every project I work on is custom-built around the client’s workflows, I don’t build templates, I build systems.
My automations integrate seamlessly with tools like Make,com, n8n, Zapier, Twilio, VAPI, and Google Workspace, connecting your CRM, calendar, voice, and messaging channels into one cohesive ecosystem.
Examples of my Work:
• AI Outreach System (Real Estate Agency - Ascend Agency)
→ Engages leads through outbound calls and SMS using natural sales dialogue, objection handling, and qualification logic.
→ Fully integrated with CRM for automatic lead updates and appointment booking.
→ Result: Automated ≈ 90% of the outreach workflow and increased closing rate by ~25%.
• AI Chatbot Assistant (Kube Coworking)
→ Handles customer inquiries across WhatsApp, Instagram, and Web chat.
→ Qualifies leads, adds them to Pipedrive, notifies the team, and supports live transfers.
→ Result: Automated 80% of intake and boosted booked trials & tours by 30%.
• AI Backend Automation (Law Firm – Expungement System)
→ Built the backend for an AI SaaS that automates legal document processing end-to-end.
→ Uses Puppeteer to scrape and cross-reference court data, GPT-based AI to extract key details, and n8n on DigitalOcean to auto-fill legal forms.
→ Result: Processes 1,000+ requests per month, saving 2,500+ lawyer hours (~$125K–$375K/year) in admin work while remaining scalable for new regions and case types.
Some of the Tools I Use:
🤖 Chatbots: Voiceflow · Botpress · n8n Chatbots
🎤 Voice Agents: Retell · VAPI · Bland · LiveKit
🔁 Automations: Make,com · Zapier · n8n · Puppeteer
📞 VoIP & Communication: Twilio · Vonage · Google Voice
💬 Large Language Models (LLMs): GPT-5 · Claude 4.7 · Gemini · LLaMA
🗣️ Speech-to-Text (STT): Deepgram · OpenAI Whisper
🔊 Text-to-Speech (TTS): ElevenLabs · OpenAI · Cartesia
💻 Programming & Scripting: Python · JavaScript · JSON
Clients love working with me! Here’s what one client said:
⭐⭐⭐⭐⭐“Outstanding freelancer, would use again, and again and again!” - Kene O.
⭐⭐⭐⭐⭐“Haroon went above and beyond. He built, tested, and iterated on our AI caller/chatbot system.” - Ascend Agency
Every project is designed to deliver measurable ROI from day one, by strategically harnessing the power of AI & Automation.
My goal is to help businesses strategically harness AI. If this sounds like something you’re interested in, don’t hesitate to contact me!
