Job Success
Karachi, Pakistan - 11:30 pm local time
My strongest work sits at the intersection of AI automation and production software: I can design the workflow, connect the APIs, build the backend, and create the web app or dashboard around it. That means you do not need one person for automation and another person for the product layer.
What I can help you build:
- n8n workflow automation for business operations
- OpenAI / Anthropic / LLM integrations
- AI chatbots for lead qualification, support, and internal workflows
- WhatsApp, Twilio, Telegram, Instagram, ManyChat, Tidio, and Botpress automation
- API integrations between CRMs, SaaS tools, websites, databases, and internal systems
- Human-in-the-loop approval workflows with logging and review steps
- Next.js, React, Node.js, NestJS, and TypeScript applications
- SaaS MVPs, dashboards, booking systems, payment flows, and admin panels
- Bug fixes, performance improvements, and technical debt cleanup
Technical stack:
- Automation: n8n, OpenAI API, Anthropic, ManyChat, Tidio, Botpress, Twilio
- Frontend: Next.js, React, TypeScript, JavaScript, Tailwind CSS
- Backend: Node.js, NestJS, REST APIs, API-first architecture
- Databases: PostgreSQL, Supabase, MongoDB, Firebase
- Integrations: Stripe, Google APIs, Slack, Firebase, webhooks, third-party APIs
- Deployment: Vercel, Cloudflare, Docker, GitHub workflows
Examples of systems I can deliver:
- AI lead qualification workflow that captures, scores, and routes leads
- n8n automation with human approval, email notifications, and database records
- AI chatbot connected to a website, CRM, or business knowledge base
- WhatsApp or Twilio workflow for client communication and follow-ups
- SaaS dashboard with secure backend APIs and payment integration
- React/Next.js bug fixes and production stabilization
Why clients work with me:
- 11+ years of software development experience
- 100% Job Success on Upwork
- Strong full-stack background, not just no-code automation
- Clear communication, practical recommendations, and reliable delivery
- I build maintainable systems that can grow after the first version
If you need an AI automation, chatbot, API integration, or SaaS feature built properly, send me a message. I will help you choose the cleanest approach and turn it into a working system.
