Full Stack SaaS & AI Developer — React, Next.js, Node.js, Python, LLM/RAG

I build multi-tenant SaaS platforms and AI features that ship to production and stay stable under real usage. I work with founders and growing teams to deliver tenant-isolated architecture, role-based permissions, billing and subscriptions, reporting dashboards, and LLM-backed features with proper guardrails so AI output stays reliable instead of unpredictable.

What I build:

• Multi-tenant SaaS architecture (tenant isolation, RBAC, billing)
• LLM and RAG features (chat, document Q&A, generation, agents)
• Multi-model AI orchestration with fallback and cost monitoring
• Custom dashboards, admin panels, and client portals
• Subscription and billing systems (Stripe, Razorpay)
• API integrations and workflow automation

Selected work:

NexOPD — Multi-tenant healthcare SaaS. Clinics run independently under one platform, with role-based dashboards for doctors, admins, pharmacists, and patients, appointment scheduling, pharmacy workflows, and AI-generated clinical notes gated by clinician approval before anything is finalized. Billing via Razorpay.

PowerSlides — Multi-LLM orchestration engine. A Python service that generates presentations by orchestrating multiple LLM providers (Anthropic, OpenAI, Gemini) with automatic fallback and per-request model selection. Every model call is scored on output quality and token usage, and credit consumption is measured across providers.
