Raj J.

Need to build an AI-powered SaaS product or add AI capabilities to an existing application? I help startups and businesses design, build, and scale SaaS products with practical AI capabilities, from product architecture and technology selection to AI integration, cloud architecture, and production deployment. With 12+ years of experience in software, SaaS, and product development, I understand both sides of the problem: building reliable software and figuring out where AI actually makes the product better. I work with technologies and platforms such as OpenAI/ChatGPT, Claude, Cohere, RAG, LLMs, and AWS, and can help you turn these technologies into real product features rather than simply adding an AI chatbot. Whether you are starting with an idea or have an existing SaaS application, I can help with AI architecture, SaaS architecture, development, integration, and deployment. ✅ AI / LLM Work OpenAI API integration AI SaaS platforms Resume tailoring systems Agentic workflows Prompt orchestration AI-assisted automation ✅ CMS Wordpress ✅ Frontend React.js JavaScript Next.js (App Router, SSR/ISR) Angular TypeScript Tailwind CSS ✅ Backend Node.js (Express / Fastify / NestJS) PHP Python (FastAPI / Django) REST APIs OAuth / JWT / RBAC Stripe integrations ✅ Desktop Development Electron (Windows & macOS) Cross-platform packaging OS integrations Auto-update systems ✅ Database & Infra PostgreSQL Supabase MongoDB CI/CD Cloud deployments (AWS / Vercel)
