Sarmad Sultan A.

I turn manual business processes into automated systems that run on their own: AI agents, voice agents, n8n workflows, APIs and the full-stack apps around them. One engineer designs, codes and ships all of it, with no hand-offs. Typical work: AI receptionists and outbound calling agents, invoice and document automation, CRM and lead pipelines, MCP servers that connect Claude to your systems, and AI-powered SaaS products. ▸ WHAT I BUILD → End-to-End Automation with n8n, Make and Zapier, plus custom Python or Node services where no-code runs out → AI Agents, RAG Pipelines and Chatbots over your data, for web, WhatsApp and support → Voice AI Agents and AI Receptionists using Vapi, Retell, ElevenLabs and Twilio → Autonomous Sales and Acquisition Agents: voice and WhatsApp outreach that qualifies leads, books meetings and updates your pipeline → Invoice, Email and Document Automation with Claude and OCR → MCP Servers and Claude Integrations that connect AI to your business systems → API Integrations and CRM Automation with GoHighLevel, HubSpot, Pipedrive and Salesforce → Retail and Inventory Platforms that sync tills, stores and suppliers → AI-Powered SaaS Products: React and Next.js front end, API backend, billing, deployment ▸ WHAT I'VE SHIPPED ◆ Retail operations platform for a multi-store fragrance retailer: supplier invoices become Lightspeed purchase orders in about 5 minutes ◆ Cail AI: autonomous car acquisition for German used-car dealers, with an ElevenLabs voice agent, a German WhatsApp agent, Calendly booking and an Asana pipeline ◆ LISA: a 24/7 AI receptionist SaaS with emergency triage, booking, warm handover to a human and GoHighLevel sync ◆ AI receptionist for a dental practice, built on Retell AI ◆ Video generation SaaS: multi-tenant platform with Stripe billing ◆ PostCraft: a RAG content platform for persona-based LinkedIn ghostwriting ◆ ERPNext MCP server: lets Claude read and write a company's ERP through 17 tools ◆ n8n, Make and Zapier systems: lead enrichment, AI qualification, outreach, CRM sync ▸ PROVEN RESULTS ◆ Invoice to purchase order in about 5 minutes, in production since March 2026 ◆ 1,294 of 1,294 barcoded invoice lines matched across 21 invoice layouts ◆ 154,000 catalogue items synced nightly across three Lightspeed accounts ◆ Video SaaS reached 500+ beta users in 8 weeks and $12K MRR in month 3 ◆ Built with human approval gates, audit trails and fail-safe defaults, so uncertain cases wait for a person ▸ HOW I WORK 1. You send me the process or idea. 2. I reply with a clear plan and scope before anything is built. 3. You get a working first version fast. Where AI makes decisions, there are approval gates and audit trails. 4. Clear handover and support after launch. ▸ CORE TECH STACK ◆ AI and LLM Engineering → OpenAI | Claude (AWS Bedrock) | LangChain | LlamaIndex → RAG Pipelines | Qdrant | Prompt Engineering → MCP Servers | Agent Workflows ◆ Voice and Messaging AI → Vapi | Retell | Bland | ElevenLabs | Deepgram → Twilio | Telnyx | WhatsApp → AI Receptionists | Outbound Calling Agents ◆ Automation Platforms → n8n | Make | Zapier → GoHighLevel | HubSpot | Pipedrive | Asana → Microsoft 365 | Graph API | SharePoint ◆ Full Stack Development → Python | Flask | FastAPI | Node.js | Express | NestJS → React | Next.js | TypeScript → PostgreSQL | MongoDB | DuckDB | Redis ◆ Cloud and DevOps → AWS (EC2, S3, Textract, Bedrock) | Docker | nginx → Stripe | Webhooks | REST APIs ▸ INDUSTRIES SERVED → Retail and eCommerce → Property Management and Real Estate → Automotive Dealers → Service Businesses and Customer Support → SaaS Startups and Product Companies → Agencies and Operations Teams ▸ WHY CLIENTS CHOOSE ME ✔ Top Rated on Upwork ✔ One engineer accountable end to end: architecture, code and delivery ✔ 5+ years building automation ✔ Systems that fail safe: nothing uncertain is guessed, it goes to a person Send me a message with your idea and I will reply with a clear plan.
