Building productswith polarising taste

Receipts, not screenshots. Five shipped things, each with the post that started it.

   Indus — 0→1 launch in 2 weeks

   Sarvam AI · Lead Software Engineer · Indus app

   Architected and shipped the Indus app end-to-end. Launched at 4.8 on App Store, 4.6 on Play Store, with crash rate driven from 16% → 0.01%.

   “An LLM-native app, shipped in two weeks.”

   • 01Designed an MCP UI widget framework so LLMs can render rich, agentic, multi-modal interfaces inline — demoed live with Swiggy at the Razorpay FTX 2026 keynote.
   • 02Closed an OEM partnership with HMD Global (Nokia) — firmware-level organic distribution across their device portfolio.
   • 03Orchestrated AI-augmented developer workflows across the team — Cursor, custom Claude Code agents, MCP tool servers — for 3–4× faster feature cycles.

   Zamp — the AI employee

   Zamp AI · Lead Engineer · team of 5

   Built the event-based runtime that lets AI agents drive the frontend, and shipped zamp.ai with heavy motion in a week.

   “Hi, I'm Zamp, an AI employee.”

   • 01Cut dashboard time-to-interactive from 12s → 2s with SSR + render-budget audits.
   • 02Designed a global event bus so agent steps could mutate UI without prop-drilling.
   • 03Authored an internal meta-framework that took a 10-day feature down to 2.

   CRED Garage

   CRED · 0→1 · team of 2

   A real-time 3D garage for vehicles, with a custom Three.js wrapper that switched models without dropping a frame.

   “An experience crafted for the top 1%.”

   • 01Authored a wrapper that hot-swapped GLTFs and shared materials across vehicles.
   • 02Wrote the device-tier ladder — high-end got reflections, low-end got silhouettes, no one got jank.
   • 03Published the playbook internally because there were almost no resources on optimising 3D at this scale.

   NeoPop

   Open source · Co-author · team of 10

   An open-source React component library + token system. The visual language behind the CRED redesign.

   “Crafting blueprints perfectly, from dot to dot.”

   • 01Set the architecture and the conformance rules so 10 engineers shipped a single voice.
   • 02Tuned animation parity across iOS, Android and web — the same easing curve everywhere.
   • 03Open-sourced the system to 871★ and a Product Hunt feature.

   CRED Quiz & Rewards

   CRED · Game UI · feature lead

   A KBC-style timer game and a stack of CRED games where every button was a hand-built CSS 3D part — no Lotties.

   “Every interaction was a small, tactile thing.”

   • 01Built embedded buttons in native CSS 3D so the game stayed snappy on the lowest-end Android.
   • 02Shipped the quiz timer loop with sub-100ms feedback and zero layout thrash.
   • 03Became one of the top engagement features in the CRED app.
