Lahore, Pakistan - 2:31 am local time
I build AI-powered products, automation systems, and full-stack SaaS platforms using React, Node.js, Next.js, Python, AI Agents, Open AI, and modern cloud structure that go into production, not just demos.

Top Rated Plus on Upwork | 100% Job Success | $100K+ earned

I work with SaaS founders, startups, and agencies who need to ship fast without cutting corners on architecture. I have helped clients in Healthcare, EdTech, PropTech, and Fintech turn unclear ideas into working products, replace manual workflows with automated systems, and add real AI features to existing apps.

WHAT I BUILD
→ AI chatbots & assistants trained on your own data (docs, website, CRM, knowledge base)
→ RAG pipelines & document Q&A systems using vector search and embeddings
→ AI agents for lead qualification, support, reporting, and internal operations
→ Workflow automation connecting your APIs, CRM, email, Slack, Airtable, HubSpot, and n8n
→ Full-stack SaaS platforms with auth, billing, dashboards, and multi-tenant architecture
→ AI features added to existing products: semantic search, data extraction, content generation, recommendations

TECH STACK
Frontend: React.js, Next.js, TypeScript, Tailwind CSS
Backend: Node.js, Express, NestJS, Python, FastAPI
AI/LLM: OpenAI, Claude, Gemini, LangChain, LangGraph, RAG, vector search, prompt engineering, AI agents
Automation: n8n, webhooks, REST APIs, CRM & email automation
Databases: PostgreSQL, MySQL, MongoDB, Supabase, Firebase, Redis
Cloud: AWS, Vercel, DigitalOcean, Docker, CI/CD
Payments: Stripe, PayPal, subscription billing

INDUSTRIES
Healthcare: patient portals, appointment workflows, document processing, HIPAA-aware systems
EdTech: LMS platforms, AI tutors, student dashboards, assessment automation
PropTech: property management systems, listing automation, tenant/owner portals
Fintech: payment systems, financial dashboards, secure multi-tenant SaaS

GOOD FIT IF
- You want to add AI features to an existing product
- You need repetitive workflows automated end-to-end
- You want a chatbot or AI agent trained on your own data
- You need a senior dev who understands both full-stack engineering and AI, not just one or the other
- You have been burned by a freelancer who delivered a "demo" instead of something that actually runs in production

I think like a product partner first. Send me your workflow or product idea and I will tell you the fastest reliable way to build it, including what I would skip or simplify to save you time and budget.
