Services & pricing
Freelance web development and AI agent development, remote-first and worldwide. Direct communication, fixed project quotes, no account managers.
Custom websites and web applications built with React, Next.js, and modern backend APIs — fast, responsive, SEO-ready, and production-grade.
Custom AI agents that automate real tasks — integrating with your tools, calling APIs, and acting autonomously using LLMs and orchestration.
Retrieval-augmented chatbots and knowledge assistants that answer accurately from your own documents or product data — not generic model guesses.
Automated internal workflows connecting your tools and data — custom scripts, API integrations, and pipelines that remove manual, repetitive work.
Starting prices below — every project gets a fixed quote after a short scoping call.
Yes. You work directly with Sidhant Singh Rathore over WhatsApp or X — no account managers, no handoffs between sales and delivery.
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.
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.
Indicative starting prices are published upfront, and every project gets a fixed quote after scoping — no surprise hourly overruns.
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.

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.
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.
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).
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.
