Full-stack & AI developer building SaaS platforms, AI-powered products, and cross-platform mobile applications — from requirements and design through to production deployment.

- Available for work on Upwork: https://www.upwork.com/freelancers/lavesh
- SaaS Platforms — multi-tenant subscriptions and billing (Stripe / Razorpay), proration, dunning, role-based access control, and admin dashboards with analytics
- AI-Powered Products — RAG systems with source citations, LLM chatbots and agents (OpenAI / Claude / Gemini), OCR and document intelligence, and self-hosted models (LLaMA / Mistral)
- Mobile Apps — cross-platform iOS and Android with React Native, including offline behaviour, push notifications, deep linking, permissions, and store submission

Every project starts with documented feature specs — screens, user actions, success and error states, and edge cases — with clear acceptance criteria so "done" is never ambiguous. Designs are reviewed against requirements before development begins, and everything is tested against signed specs before delivery.
