Hi, I'm Arkadev Banerjee 👋

Distributed-systems engineer · SDE-II @ CityMall · Kolkata, India

I build the invisible systems that move commerce — orders, catalogues, capacity, caches — and the AI agents that run on top of them.

🌐 Portfolio

arkadevbanerjee.github.io/arkadevbanerjee — an interactive 3D "living distributed system": a WebGPU/WebGL constellation of microservices with packets of light flowing between them, flown through as you scroll.

🚀 Projects

  • submux (Go) — local relay that lets one Claude Code session run each subagent tier on a different subscription, passing your own OAuth through untouched.
  • grammar-fix-hotkey (Lua) — macOS hotkey that fixes grammar and translates selected text in place, via a fast free LLM on Groq and Hammerspoon.

🛠️ Stack

  • Languages: TypeScript / Node.js · Go · Python · Java · Rust · C
  • Datastores: PostgreSQL · Redis · MongoDB · DynamoDB
  • Infra: Kafka · Docker · AWS · microservice architecture
  • AI era: LLM agents · AI-assisted engineering · human-in-the-loop tooling

💼 Experience

  • SDE-II @ CityMall (Oct 2023 – present) — warehouse & logistics capacity optimization, atomic inventory systems (Redis + Lua), operations infrastructure
  • SDE-I @ CityMall (Dec 2021 – Oct 2023) — distributed product catalogue, ground-up order-service rewrite, ML recommendation systems, pricing scrapers
