About

I’m a full‑stack developer who likes building practical things: gen‑AI apps, low‑code tools, and products that solve my own problems as a developer. I currently work at CRISIL as a Software Developer, building: An in‑house Gen‑AI flow builder (React Flow style nodes: model, input, output, RAG) A visual editor for S&P Global’s internal AI flow language (FDL), turning a text DSL into a node‑based UI Features for an internal low‑code platform that generates Angular apps from drag‑and‑drop UIs Previously at Sankey Solutions (3 years): Built a reusable chatbot frontend with React Web Components Helped ship a high‑traffic Next.js news site (~8M users, faster page loads) Delivered e‑commerce and animation‑heavy web experiences On the side, I’m the solo builder of surflux.io – a multi‑model AI chat and image generation platform built with Next.js, Node.js, Go, and MongoDB. It’s my way to learn AI + Go by shipping real features, not just tutorials. Stack: React, Next.js, Angular, Node.js, Go, Express, Hono, MongoDB, PostgreSQL, AI APIs, Docker. Always open to connecting with engineers, AI builders, and founders.

Full‑stack developer focused on Gen‑AI platforms and low‑code tools for CRISIL and its parent company S&P Global, using React, Angular and Node.js.
Key work & impact:
Designed and built an in‑house Gen‑AI application using React and React‑Flow concepts, where users create flows with nodes such as Model, Input, Output, and RAG. This allows non‑technical users to compose LLM workflows and retrieval‑augmented generation (RAG) pipelines visually instead of writing code.
Created a node‑based visual editor for S&P Global’s internal Flow Definition Language (FDL), a text‑based AI orchestration DSL. Defined JSON schemas for different node types and generate valid FDL behind the scenes. This turned complex, error‑prone text configurations into intuitive flow diagrams. A POC was delivered in about a week, and a fully usable solution in ~2–3 months.
Contribute to Myron, CRISIL’s long‑running internal low‑code platform used for internal tools and applications. Work on the canvas where users drag‑and‑drop UI components and generate equivalent Angular applications and backend configurations. Focus on improving the canvas UX and adding new capabilities.
Started exploring a React‑based low‑code tool, including architecture, component model, and a custom transpiler concept to convert canvas definitions into exportable React code.
Collaborate with architects and product owners on system design and reusability for internal products, especially around AI flow tooling and low‑code experiences.
Tech: React, Angular, React‑Flow concepts, Node.js, TypeScript, internal DSLs (FDL), REST APIs, Gen‑AI integrations.

Software Developer

Jul 2021 – Jul 2024 · 3 yrs · Thane, Maharashtra, India

Full‑stack developer working on AI chatbots, high‑traffic media sites, and e‑commerce platforms using React, Next.js, Node.js and Magento 2.
Key work & impact:
Developed a chatbot agent with Rasa as the backend and React JS Web Components on the frontend. The same frontend codebase runs across multiple client websites and mobile apps (React Native), reducing duplication and maintenance effort.
Implemented a server‑driven UI for the chatbot, where JSON from the server controls the layout and behaviour. This allowed the same frontend to support multiple Rasa bots with different flows and designs.
Built and maintained a Next.js news website for a major Indian media company, helping them reach ~8M users. Worked on SEO features, third‑party integrations, and analytics, and optimized performance by improving page load time from ~5s to 1.8s. Also handled migration from Next.js 10 → 11.
Created dynamic RSS feed logic in Express.js, allowing agencies to generate topic‑specific RSS feeds just by passing parameters, making integration much easier.
Developed an e‑commerce solution for a UAE client using Magento 2 as the backend, React JS as the storefront, and React Native for the mobile app.
Built a highly animated design agency website using GSAP and fullPage.js, translating abstract visual ideas into a smooth, production‑ready experience.
AI & recognition:
Hackathon Winner (Oct 2023): Built a document summarization agent using Mistral LLM and vector storage. It understands both English and Hinglish (Hindi written in English) and can retrieve the right contact (e.g., HR, CEO) from policy documents. This prototype was later pitched to clients and helped generate AI‑related engagement.
Top Performer (Q1 2023): Awarded for exceptional productivity and delivery quality across multiple client projects.
Tech: React, Next.js, React Native, Node.js, Express.js, Rasa, Magento 2, GSAP, fullPage.js, REST APIs, Google Ads, Taboola.
