Building full-stack products · Bengaluru, India

Yup, I'm a software engineer — the kind who gets weirdly happy when a payment webhook finally reconciles. I build products end-to-end with React, Next.js, TypeScript and Node on AWS, and I spend most of my day inside the terminal.

Right now I'm at Figrfast Systems in Bengaluru, shipping payment gateways, media pipelines, and LangGraph-powered AI systems.

📌 pinned philosophy

Ship it, then sweat the details.

I started writing code in college in 2021. The first year was mostly me fighting the basics and losing — but somewhere between the failed builds, shipping things people actually use became the whole point.

Since then I've built payment flows that move real money, upload pipelines that crunch real files, and AI systems with real token bills. That's the part of engineering I love: when the code stops being an assignment and starts being a product.

The gap between a demo and a product is a hundred boring details — and I genuinely enjoy the boring details.

Figr AI — building the core product

Moved from plugins to the main Figr AI app — a React Flow-based canvas that went from eight months of beta to public launch in Dec 2025; converted to full-time in May 2025.

app.figr.design

Converted the entire app into a whiteboard-style canvas (Apr 2026) — commenting, sticky notes, prototype rendering, and more.
Integrated the Stripe payment gateway end-to-end — checkout, credit provisioning, and integer-cents capture across 7 charge paths.
Built the event-driven “Earn Credits” rewards system — an idempotent ledger with an atomic-increment concurrency guard, plus Mixpanel revenue instrumentation.
Designed the asset-upload system — S3 presigned-URL client-direct uploads with AWS Lambda pipelines that compress assets and auto-generate thumbnails.
Shipped a full-stack contextual nudge engine — 13 in-product nudges live in production, authorable by non-engineers.
Led UI across the design-system management surface and the React Flow canvas — query-diff view, Figma import, admin tooling.

Feb 2025 – Mar 2025

Nexus — Figma file auditor

Built a plugin that reads an entire Figma file in batches and processes every node to audit design health — design-token usage, font sizes, and a battery of other consistency criteria.
