About

  • ·Software Engineer at Halma India, shipping across the stack — Kafka-based ingestion pipelines, NestJS backends, and Angular / Vue / React frontends for IoT and GIS products.
  • ·I care about clean architecture and developer ergonomics. Recently led a multi-repo → monorepo migration and stood up a RAG-powered onboarding chatbot for our team.
  • ·Outside work I build small, opinionated tools and weird browser games. Big believer in continuous learning, polish, and a little playful curiosity in everything I build.

  • ·Engineered a Kafka-based ingestion system (NestJS) handling a 60× surge from 1,000+ IoT devices across 30+ clients — eliminated packet loss at scale.

  • ·Shipped a v2 overhaul of an enterprise SaaS platform — Angular frontend + NestJS backend, complete architectural and UI refresh.
  • ·Migrated a distributed multi-repo codebase to a Turborepo + pnpm monorepo, improving shared-code reuse, build consistency, and team maintainability.
  • ·Built a RAG-powered internal chatbot (Python) so new joiners can query device docs, protocols, and product knowledge — reduced onboarding friction.
  • ·Introduced the Karate API testing framework; ran 4 × 3-hour training sessions for QA and Dev, standardizing test docs and coverage.

  • ·Each puzzle has a fair, hidden, logical solution
  • ·Game state in localStorage — fast loads, offline-capable
  • ·Frame-perfect Framer Motion micro-interactions are part of the puzzle
