About
Yuvraj Singh is a software developer and Forward Deployed Engineer based in India. He builds full-stack products, AI systems and automation for real operational workflows. He has shipped four live products — Xpress Writers, Potato RFQ, Potato Bazaar and Admivo — and writes up the engineering behind each one.
The work is one path, run four times: sit with the people who run a process, design the system that replaces the manual parts of it, and carry that system from a working prototype to something in production the team owns. I work across product, frontend, backend, automation, and infrastructure. The part I enjoy most isn't writing code — it's figuring out what the code should do.
Areas of work
Four lines, taken from the record rather than written for this page. Each is evidenced by at least one of the products below.

Prototype-to-production delivery on full-stack SaaS
Mapping operations pain (RFQ, documents, dashboards) to working AI systems
Token optimization and prompt engineering for reliable production systems
Technical specialties
Products
A customer-facing marketplace connecting clients with expert writers — real-time orders, role-based dashboards, and workflows a non-technical team can run.
Yuvraj Singh's role · Full-stack engineer — end-to-end architecture, REST APIs, the real-time layer, and the role-based dashboards
B2B RFQ system for sourcing potatoes at scale — post requirements, collect competitive quotes, and move from supplier discovery to orders.
Yuvraj Singh's role · Forward Deployed Engineer — mapped RFQ, delivery, and supplier operations into a multi-tenant product with operations stakeholders
India-facing potato marketplace with live prices, trade connections, and production AI — RAG, MCP agents, and LLM workflows for operations staff.
Yuvraj Singh's role · Forward Deployed Engineer — production RAG, embeddings, MCP tool-calling agents, and the operations workflows they sit inside

Questions
Yuvraj Singh is a software developer and Forward Deployed Engineer based in India. He builds full-stack products, AI systems and automation for real operational workflows, and has shipped four live products: Xpress Writers, Potato RFQ, Potato Bazaar and Admivo.
Yuvraj Singh builds multi-role SaaS products, multi-tenant B2B platforms, document and application workflows, and production AI systems — retrieval-augmented generation, embeddings, LLM workflows and MCP tool-calling agents. The work starts from a process people run by hand and ends as software the team running it owns.
Yuvraj Singh works in TypeScript, JavaScript, Python and SQL, with React.js and Next.js on the front end, Node.js and Express.js behind REST APIs, PostgreSQL and MongoDB for data, and Socket.IO for real-time. His AI work uses retrieval-augmented generation, embeddings, tool calling and the Model Context Protocol.
Yuvraj Singh developed Xpress Writers (xpresswriters.in), Potato RFQ (RFQ product), Potato Bazaar (potatobazaar.com) and Admivo (admivo.in). Each one is live, and each has a case study on this site covering the constraints it was built under, the system that came out of them, and every significant decision beside the alternative it beat.
A Forward Deployed Engineer builds alongside the people who run a process rather than from a specification written about it: mapping the real workflow with those stakeholders present, building against what they actually do, and carrying the result from prototype into production. Yuvraj Singh holds that role at SK Agri Exports, where RFQ, delivery and supplier operations became a deployed multi-tenant product.
Potato Bazaar is the only one. Its AI layer runs retrieval-augmented generation with embeddings, LLM workflows and MCP tool-calling agents in production. Xpress Writers, Potato RFQ and Admivo are full-stack products with no AI component, and this site does not claim otherwise for them.
All four products are live and linked from this page. Code is at GitHub, professional history at LinkedIn, and the engineering write-ups are at syuvraj.in/work.
