About Hassan
Senior AI Engineer + Full-Stack | SaaS, React.js, MVPs, Chatbots
100%
Job Success
Lahore, Pakistan - 2:40 pm local time
I build production-grade SaaS web apps, mobile apps, AI chatbots, and AI agents — end to end. Senior engineer with 8+ years of experience; I've shipped products solo and led small teams when the project needed it.
Most projects are a mix — AI integration, chatbot work, and full-stack web/mobile builds, often all at once.
WHAT I BUILD
▸ AI-powered SaaS platforms Multi-tenant SaaS in Next.js + Postgres/Supabase + Stripe. Auth, billing, dashboards, admin panels. MVP in 2–6 weeks; ongoing for production. Full-stack development, end to end.
▸ Mobile apps with AI React Native + Expo cross-platform. Native iOS/Android when needed. Push, offline sync, deeplinks, subscriptions. AI features integrated cleanly (chat, voice, RAG, OCR).
▸ AI chatbots & RAG systems Custom chatbot development with Claude (Anthropic) or GPT, trained on your docs, PDFs, CRM. Vector search (Pinecone or Supabase pgvector). Citation-backed answers. Delivered on web, WhatsApp, or Slack.
▸ AI agents & automation Multi-step AI agents with LangChain / LangGraph + MCP tool servers. Document processing, lead qualification, research, internal-ops automation. Hooked into Make, n8n, Zapier — automation expert across the major no-code platforms.
▸ AI integration into existing apps Drop Claude, GPT, or Gemini into the app you already have. Connect AI to your existing CRM, dashboards, and tools. The most common project type — fast retrofit, clear ROI.
▸ Voice & calling agents Vapi, Retell, Bland, ElevenLabs, Deepgram, Twilio, LiveKit. Sub-200ms inbound/outbound, CRM dispositioning, appointment booking. Built when the project calls for it.
▸ Chrome extensions & internal tools Manifest V3 extensions, scraping/automation tools, admin dashboards.
▸ Vibe-code cleanup & deployment Lovable, Bolt, Replit, Cursor projects that need real engineering: production refactor, security, deploy pipeline, debugging, scaling.

HOW I WORK
Spec first. Loom walkthrough before I write code so we agree on scope.
Production-grade output: auth, error handling, deploy pipeline, README, handover.
0–4 hour response time, typically start within 24–48 hours of contract signing.
I write the code myself.
If you want a 15-min demo of working systems before you commit, send a brief and I'll send a Loom of similar past work.
