// 01 — About

Full stack, end to end
backend · AI · Meta API · DevOps

I am a Full Stack Developer and AI Automation Engineer with 3+ years of hands-on experience building production systems for real clients. I cover the full stack — backend APIs, AI agents, Meta API integrations, ad funnels, automation pipelines, and DevOps — so a client only needs one person to ship the whole product. My main work right now is ChatPilot, a live WhatsApp CRM with AI bots used by clinics and agencies in Pakistan and the UAE. On Upwork I am a top-rated freelancer with 5.0 reviews, working with clients in the UAE, Europe, and the US on WhatsApp Business setup, Meta Ads funnels, n8n / Make.com automation, voice and call agents, and Claude Code agentic systems.

I work like a one-person team — backend, frontend, AI, database, Meta API, ad funnels, automation, and deploy all done by me. No handoffs, no "that's not my job" when something breaks. My live SaaS is ChatPilot, a WhatsApp CRM with AI bots used by clinics and agencies today.

On Upwork I am a top-rated freelancer with a 5.0 rating — clients call me a "Great Full Stack Developer". When I am not shipping client work, I am solving algorithm problems — 700+ LeetCode done and joined ICPC 2025 Regional.

ChatPilot

WhatsApp CRM with AI Bots

A multi-tenant WhatsApp CRM built for clinics and service businesses. AI bots chat with customers 24/7, staff can take over any time, and many businesses run on the same system without sharing data.

  • Multi-tenant SaaS with full data isolation
  • AI bots that reply 24/7 with smooth handover to staff
  • Live message handling and full chat history
  • Bulk campaigns and scheduled messages
  • Auto deploy with GitHub Actions on DigitalOcean

// 04 — AI & Automation

From AI agents
to live business
automation.

I build the entire AI infrastructure layer — agents, workflows, and integrations — that connect everything from Meta Ads to Stripe into a single intelligent system.

AI Agents

Chat, Voice & Call Agents

I build AI agents that plan steps, use tools, remember things, and fix errors on their own — chat, voice, and full call agents that talk to customers in real time.

  • WhatsApp lead bots that talk to customers
  • Voice and call agents with OpenAI Realtime
  • Content bots that turn one video into many posts
  • Office bots that read Slack and write reports
Meta API & WhatsApp

WhatsApp & Meta Cloud API Expert

I connect WhatsApp Business and Instagram to your system using the official Meta Cloud API — template approval, business verification, and Embedded Signup all handled.

  • ChatPilot — a live WhatsApp CRM I built
  • Approved message templates for marketing
  • Embedded Signup for one-click client onboarding
  • Instagram Graph API for DM automation
Meta Ads & Funnels

Meta Ads Funnels & Tracking

I build full Meta Ads funnels — Pixel, Conversion API, audience targeting, and dashboards that tell you exactly which ad turned into which paying customer.

  • Meta Pixel and Conversion API setup
  • Custom audience and lookalike funnels
  • Lead tracking from ad click to sale
  • Live dashboards for ROI and CAC
n8n & Make Workflows

Visual Automation with n8n & Make

I make custom n8n and Make.com flows that connect AI agents to your business apps. Easy for non-tech people to use and edit later.

  • Custom n8n nodes for any API
  • AI nodes for OpenAI and Claude
  • Self hosted n8n on DigitalOcean with Docker
  • Make.com scenarios with branching logic
Claude Code Automation

Claude Code Agentic Systems

I build agentic systems with Claude Code — custom MCP servers, Slack and GitHub integrations, and AI workflows that ship real code and run real ops.

  • Custom MCP servers for client tools
  • Claude Code agents for code review and ops
  • AI-driven CI/CD and deploy pipelines
  • Internal tools that read Slack and act
Real Use Cases

What I Have Built for Clients

Real systems for real businesses. These are not demos — they run in production today and earn money for clients.

  • WhatsApp lead bot for healthcare clinics
  • Auto pricing SaaS that updates Shopify daily
  • Meta Ads funnel for an e-commerce brand
  • Voice call agent for a sales team
