On Upwork: 3,500+ hours, 98% Job Success Score. Manual back-office work eats hours your team does not have. I automate it end to end — from the first trigger to the final output — so the people in your process can focus on the work only they can do. WHAT I BUILD AI agents Multi-step agentic workflows with tool calling, RAG pipelines, and human-in-the-loop approval gates. Lead qualification agents that score and route in real time. Document-processing agents. Internal support agents wired into your live CRM, ticketing system, and knowledge base — not a static FAQ. Built on LangChain, LangGraph, OpenAI, and Anthropic Claude. Workflow automation n8n, Make, and Zapier — self-hosted or cloud. Lead routing, invoice and document processing, report generation, ticket triage, timesheet and approval flows, data sync between systems that were never designed to talk to each other. Conversational automation Real-time voice agents on Twilio, Telnyx, and Retell AI (official dev partner) — including CRM integration, warm transfer, and human-like interruption handling. WhatsApp Automation, Slack and web chat wired into real business logic: CRM lookups, order status, booking, and clean escalation to a human at exactly the right moment. System and API integration REST and GraphQL APIs, webhooks, OAuth, retries, and idempotency. Salesforce, Zoho CRM, HubSpot, Kommo, SharpSpring, QuickBooks Online, Airtable, Notion, Google Workspace, Slack. SQL and NoSQL data layers. RECENT WORK — Retell AI dev partner integration suite: built and documented voice-agent connectors for Salesforce, Zoho CRM, Airtable, Notion, Google Workspace, Slack, Epic and Lovable — production-ready with full implementation guides for each. — Timesheet automation (n8n): eliminated ~8 hrs/week of manual data entry across 40+ employees. Zero missed approvals since go-live. — AI call-quality pipeline (OpenAI + LangChain): 200+ calls scored per day in under 3 minutes vs a 45-minute manual review — 15x QA throughput. — AI invoice monitor — CostSaver (Python + FastAPI): flags cost anomalies within hours of transaction. Full server-side rebuild, delivered on schedule. — Live weather data pipeline (n8n + BI layer): cut data refresh lag from 6 hours to under 15 minutes with zero-touch automated ingestion.

Steps, systems, exceptions, and who currently does what. Automating a broken process just makes it fail faster. — Error handling and alerting are in scope by default, not phase two. An automation that fails silently is worse than no automation. — You own the workflows and the credentials. If it is n8n, I can hand it to you self-hosted and fully documented so you are not locked to me. — Milestones with written acceptance criteria, or hourly with daily updates. I respond within 2 hours and deliver a workflow map and estimate within 24 hrs. Send me the process you want automated, the steps, the systems involved and where it currently breaks. I will map the workflow and give you an estimate within 24 hours. Best, Muhammad Zaman
