Saad S.

Full-Stack AI & CRM Developer | React, Next.js, HighLevel, HubSpot

I'm a full-stack developer specializing in AI-powered SaaS development, CRM automation, and API integration — 23 projects delivered, $100K+ earned on Upwork, 100% production-ready builds with senior-level architecture. If your last developer took 6 months and delivered nothing, or your HubSpot or HighLevel account is leaking leads and nothing talks to each other — that's exactly the kind of mess I fix. ⚡ AI-Powered SaaS & MVP Development I ship AI SaaS MVPs in 4–8 weeks using React, Next.js, Supabase, Node.js, and OpenAI/Claude API integration. Full authentication, admin dashboards, Stripe billing, and AI features built in from day one — not bolted on later. Web application development that's ready for real users, not a demo. 🔄 CRM Automation, HubSpot & HighLevel Integration, Data Migration Broken workflows, leaking leads, disconnected tools — I rebuild CRM systems properly. Recently completed a CRM data migration of 70,000 contacts from HubSpot to HighLevel and rebuilt the entire automation workflow from scratch. I handle HubSpot workflows, HubSpot API integrations, HighLevel automations and snapshots, Salesforce, and custom CRM logic when off-the-shelf doesn't cut it. 🔗 API Development & Integration Complex API integrations that keep breaking? Stripe, REST, GraphQL, webhook chains, HubSpot API, HighLevel API — I build API integrations that hold up in production. Clean data flow between systems, proper error handling, and nothing silently failing at 2am. Custom API development with Python and FastAPI when you need your own backend. 🤖 AI Integration & Automation I integrate OpenAI API, Claude, and other LLMs into existing products — AI chatbots, document processing, workflow automation, and AI features that create real business value, not gimmicks. 📱 Mobile + Web Apps One codebase, every platform. React Native + Expo with shared business logic, deployed to iOS and Android with the same quality standards as my web builds.
