You will get I will integrate AI into your existing app or SaaS
Project details
You already have a product. What you don't have is the AI feature your users keep asking for, and bolting one on badly is worse than not having it.
I add AI to apps that already exist, without a rewrite. A copilot inside your dashboard, smart search across your users' content, auto-summaries, recommendations, built into your real UI and backend so it feels native, not like a chatbot taped to the corner.
This is the difference that matters: I'm a full-stack engineer, not just an AI layer. I work inside your existing codebase (Next.js, React Native, FastAPI, Postgres, whatever you run), wire the AI into your real data, and ship it to production.
It's also built right: proper prompts, retrieval where it helps, and guardrails so it doesn't hallucinate in front of your users.
Not sure how it'll work in your product? Start with the AI Feature Proof, I build a working version of your core feature in 3 days so you see it live before committing to the full thing.
Tell me what your product does and the feature you want, and I'll tell you how to build it in.

Devendranagar, India - 10:31 am local time
Looking for an engineer who can build your complete AI-powered product not just the frontend, backend, or AI layer?
I design and build production-ready AI applications from concept to deployment, combining modern full-stack engineering with LLMs, agentic workflows, and scalable cloud infrastructure. Whether you're launching a new AI SaaS platform, integrating AI into an existing product, or building an internal automation system, I deliver solutions that are reliable, maintainable, and built for real users.
I work across the entire product lifecycle—from architecture and UI to backend services, AI integration, deployment, and ongoing optimization—so you can work with one engineer who understands the complete system.
What I Build
* AI SaaS platforms powered by GPT, Claude, Gemini, and other LLMs
* AI Agents using LangGraph, CrewAI, MCP, and tool-calling workflows
* RAG applications with semantic search, document intelligence, AI copilots, and vector databases
* Voice AI and conversational applications using Whisper, ElevenLabs, Deepgram, and Twilio
* Modern web applications using React, Next.js, TypeScript, Node.js, FastAPI, and PostgreSQL
* Cross-platform mobile applications with React Native and Expo
* Workflow automation and data pipelines using n8n, Playwright, Puppeteer, and third-party APIs
* Multi-tenant SaaS platforms, dashboards, marketplaces, booking systems, CRM, ERP, and custom business applications

Delivery time starts when Saurabh receives requirements from you.
Saurabh works on your project following the steps below.
Revisions may occur after the delivery date.
Scope the feature
We agree exactly what the AI feature does, where it lives in your app, and what success looks like, then I map it to your stack.
Wire up the AI
I build the AI pipeline — prompts, retrieval if needed, and guardrails — and connect it to your data and chosen model.
