I'm Prayag, a senior full-stack developer based in India. I build production software for startup founders and small businesses: SaaS products, AI assistants over company data, and the internal systems a team runs on.
Recent work, all for real clients: I was the founding engineer at 7Centre, building a ledger-scanning app and their multi-tenant ESG platform. I built OpsVanta, an internal ERP for IST Networks, on my own, working directly with the CEO; most of the company now runs on it. I built the AI analyst behind StoreFilter on 2.5 million records, and PayRight, a UK platform that checks invoices against contracts with a human in the loop.
I use AI coding tools, mainly Claude Code, and also Lovable when a project lives there, for the repetitive parts of a build. My own time goes on what decides whether a product works: architecture, data, security and reviewing every change before it ships. That is how a solo developer can deliver a system a whole company uses.
Every project starts with a 30-minute call and a written scope, so you know what you're getting and what it costs before any code is written. You own the code and the accounts it runs on.
Selected work
RAG and AI chatbots
A UK contract compliance and invoice assurance platform. AI extracts contract clauses, people confirm them, and every invoice is scored against contract and PO.
MVP and SaaS development
An internal ERP built solo with Lovable and Claude Code on Lovable Cloud, running sales, projects, tickets, collections, finance and AI insights in one place.
MVP and SaaS development
As founding engineer at 7Centre, I built a Flutter app that scans their printed Sustainability Ledger and worked on Simplii, their multi-tenant ESG platform.
RAG and AI chatbots
An AI analytics chat for e-commerce, built with Next.js, Claude Code, Supabase, pgvector and GPT-4. Ask about any Shopify store, get answers with charts.
A 30-minute call is enough to tell whether it fits, what the first version should include, and how long it takes.
