About

Frontend craft, product engineering and now AI

I am a Senior Software Engineer at Act21 Software in Noida. My work sits where frontend craft meets product engineering: I design component architecture, own the real-time and API layers behind it, and ship it for regulated banking and insurance clients.

Over five years I moved from building React interfaces to architecting a low-code platform used by 5,000+ people, leading a team of four, and now building AI into products: HyperAI, an agent that answers policy and payout questions from a single prompt, and AI UI Builder, which generates interfaces from text prompts and images.

Architecture first

Domain-driven design and reusable component systems that keep large products maintainable. DDD alone improved reuse by 50%.

Measured quality

Jest and React Testing Library took coverage from 45% to 85% and cut production bugs by 40%.

Performance you can measure

Next.js SSR/SSG work improved SEO scores and load times by 35%, and the company site loads 45% faster.

Security in the details

Keycloak SSO and role-based access for banking compliance, plus certificate-based network access for the company.

Selected projects

Real products shipped at Act21 Software. Client projects are private, so I describe the problem, my solution and the measurable result.

FeaturedAI agent chatbot · Act21 Software · 2026 - Present

HyperAI

Problem. To answer a simple policy or payout question, users had to move through multiple pages and reports.

Solution. An AI agent on the OpenAI API that understands natural language. Users ask "What is my payout for January?" and get the answer within seconds from one prompt. It can also create and configure incentive schemes from a description.

  • One prompt replaces multi-page navigation
  • Keycloak SSO and role-based access, so each user only sees their own data
  • React chat UI with a Node.js backend and engineered prompts
  • OpenAI API
  • React
  • Node.js
  • Keycloak
  • Prompt engineering
FeaturedGenerative UI for the low-code platform · HDFC Bank · 2025

AI UI Builder

What it is. An AI layer inside UI Builder. Users describe the page they want, for example "build a report page with a table", and it generates the UI. They can also start from an image, or from prebuilt templates.

  • Prompt-to-UI: build a page from a plain-language description
  • Image-to-UI: start from a reference image
  • Prebuilt templates as ready-made starting points
  • Works inside the existing low-code platform used by 5,000+ users
  • Generative AI
  • LLM
  • Prompt engineering

Low-code platform · HDFC Bank · 2023 - 2025

UI Builder

Problem. Building web and native apps meant rebuilding the same pieces over and over.

  • Used by 5,000+ users
  • 40% less development time for consuming teams
  • Real-time multi-user state sync over WebSockets
  • Taken from R&D prototype to production
  • React
  • Next.js

Incentive management system · HDFC ERGO · 2023

Hyperform
