Rimsha H.
Full Stack AI Engineer | AI SaaS MVPs, RAG, Voice Agents & Stripe
You don't need four freelancers to launch your AI product. I build AI SaaS MVPs end to end, from the Next.js frontend to the Python backend, LLM features, Stripe billing, and deployment, and ship them in weeks, not months. I'm Rimsha, a full stack AI engineer working in production with Next.js, React, TypeScript, Python, FastAPI, Node.js, PostgreSQL, and Supabase. I've built and launched 10+ AI and SaaS products across LegalTech, PropTech, ecommerce, voice AI, generative AI, and business automation. What I build: • AI SaaS MVPs: authentication, dashboards, databases, APIs, Stripe subscriptions, and deployment • AI agents and RAG systems with OpenAI and Claude, including document AI and AI support agents • Voice AI agents and AI receptionists • LLM-powered workflow automation • Stripe billing, Stripe Connect payouts, webhooks, and multi-tenant SaaS architecture • Clean, documented code with a full handover, so you're never locked out of your product Recent work: • An AI voice agent SaaS MVP for an Upwork client, rated 5.0 • ScoutCall: an AI voice receptionist • RepEasy: an AI support agent that drafts replies using customer and order context • An AI legal assistant using RAG and Claude for document analysis • PLYRS CRCL: a sports governance platform with Gemini-powered document vetting, role-based access, and Stripe Connect payouts • GPTButton: a multi-tenant AI chat widget SaaS with streaming responses and per-customer Stripe billing Why clients hire me: one engineer owns the whole flow, from UI to API to database to AI to payments to deployment. Fewer handoffs, faster launches, and honest advice on whether AI is the right fit. How I work: 1. You share your requirements, designs or references, and any existing code 2. I confirm the scope, timeline, and next steps before starting 3. Small features take 1–3 days; full applications are delivered in clear milestones with regular updates 4. Two rounds of revisions are included within scope, and I fix any issues in my implementation during testing Tell me what you're building, and I'll tell you how I'd approach it.
