Why clients hire me
Will I work directly with you, not an account manager?

Yes. You work directly with Sidhant Singh Rathore over WhatsApp or X — no account managers, no handoffs between sales and delivery.

Can you handle both the web app and the AI features?

Yes. One developer covers the whole stack — frontend, backend, and the AI/agent layer (LLMs, RAG, orchestration) — so you aren't coordinating between a web agency and a separate AI contractor.

How fast can you deliver?

Clear scoping up front and direct communication mean projects move quickly — typically 1–2 weeks for a website, 3–8 weeks for a full app or AI agent build. Replies within a day.

How much will my project cost?

Indicative starting prices are published upfront, and every project gets a fixed quote after scoping — no surprise hourly overruns.

Can I see examples of past work?

Real shipped projects, not mockups — a realtime AI call assistant, a RAG document Q&A system, an LLM routing platform, and more are on the projects page.

FAQ
Who is Sidhant Singh Rathore and what services does he offer?

Sidhant Singh Rathore (Sidhant Singh Rathore) is a freelance full-stack web developer and AI agent engineer. He builds custom websites and web apps, custom AI agents, RAG/chatbot systems, and workflow automation for startups and founders worldwide, working remotely and project-based.

Does Sid build custom AI agents and chatbots?

Yes. Sid designs and builds custom AI agents that use LLMs, tool calling, and multi-step orchestration to automate real tasks, plus RAG-based chatbots that answer accurately from a business's own documents or product data.

What is the difference between a chatbot and an AI agent?

A chatbot answers questions, typically using retrieval-augmented generation (RAG) over your documents. An AI agent goes further: it can call tools and APIs and take multi-step actions to complete tasks, not just respond in a chat window.

What tech stack does Sid use?

Primarily React and Next.js on the frontend, with Node.js/TypeScript and Python backends, plus LangChain and Hugging Face for AI work — the same stack behind his own shipped projects (a realtime AI call assistant, a RAG document Q&A tool, and an LLM routing platform).

How much does it cost to hire a freelance web developer or AI agent developer?

Indicative starting prices: a landing page or simple website from $499, a full-stack web app from $1,999, an AI agent or RAG chatbot from $999, and a workflow automation project from $399. Final pricing depends on scope — reach out for a quote based on your project.

Is Sid available for remote and international clients?

Yes. Sid works remote-first with clients worldwide, communicating directly over WhatsApp or X (Twitter) DM — no account managers or middlemen.

How do I get started or hire Sid for my project?

Message Sid directly on WhatsApp (https://wa.me/7607010648) or X, or reach him by email (sidhantsinghrathoreprsnl@gmail.com), with a short description of your project. He typically replies within a day.

Does Sid work with startups, small businesses, or agencies?

Yes, all three — founders building an MVP, small businesses needing a website or automation, and agencies that need a reliable freelance developer to extend their team on a project.

Can Sid integrate an AI agent or chatbot with my existing website or app?

Yes. Sid can integrate custom AI agents and RAG chatbots into an existing website, product, or internal tool via API, without requiring a full rebuild.
