Shahzaib R.

I help startups and businesses build, modernize, and scale production-ready AI-powered products — from full-stack SaaS applications and web platforms to AI chatbots, conversational workflows, and AI-powered features. I work end to end with Ruby on Rails, React, Next.js, Node.js, and the MERN stack, with AI integrations using OpenAI/GPT, Claude, and Gemini. With 7+ years of experience as a Senior Full-Stack Developer, I've built and scaled SaaS platforms, healthcare applications, CRM systems, fintech products, marketplaces, e-learning platforms, and custom business applications. 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐮𝐢𝐥𝐝: • AI-powered SaaS platforms, MVPs, and web applications • AI chatbots and conversational user experiences • AI agents, automation, and intelligent workflows • OpenAI/GPT, Claude, and Gemini integrations • RAG and knowledge-based AI features • Full-stack applications using Ruby on Rails, React, Next.js, and Node.js • REST and GraphQL APIs, third-party integrations, and payment systems • Legacy Rails modernization, performance optimization, and scaling • Taking over existing or unfinished codebases and getting them production-ready 𝐑𝐞𝐜𝐞𝐧𝐭 𝐀𝐈 𝐖𝐨𝐫𝐤: • AI Insurance Chatbot — Replaced a traditional form-based insurance information flow with a conversational AI experience that guides users through questions and collects structured information naturally through chat. • AI-powered application features — Integrated AI capabilities into existing web applications to automate workflows and improve the user experience. I'm most useful when you need someone who can handle both sides of the problem — the AI layer and the production-grade application around it. You'll get clean, maintainable code, practical technical decisions, and clear communication. Let me know what you've built so far and what you're trying to achieve. I'll help you figure out the most practical way forward.
