Hello, I'm Karan

I code, design systems, and solve problems.

I'm a Senior Backend Engineer at Celigo, where I work on large-scale core worker systems and distributed backend architecture.
Outside of work, I explore AI, web systems, and developer tooling — building small prototypes and learning through experimentation.


What I Do

  • Build and scale backend services in Node.js and TypeScript
  • Design reliable worker queues, microservices, and data pipelines
  • Develop frontend applications with React, Electron, and Flutter
  • Build AI-powered systems using Whisper, Llama, and FastAPI
  • Experiment with Rust for backend services and real-time systems

My Daily Stack

TypeScript Node.js Express PostgreSQL Redis MongoDB React Electron FastAPI Python AWS Git Jira


Recently Explored

  • LLM frameworks and integrations — experimenting with local Llama models, LangChain, and Whisper
  • AI-driven applications — building conversational agents and transcription tools with FastAPI backends
  • System architecture at scale — queue design, async processing, caching, and observability
  • WebAssembly and browser systems — creating lightweight terminal and runtime prototypes in Rust
  • Rust ecosystems — exploring ECS, SDL2, and low-latency backends
  • Modern frontend patterns — React performance, state management, and real-time UI with WebSockets
  • Developer experience improvements — streamlining local development, build pipelines, and CI/CD

“If it works and you don’t know why, it’s probably in production.”
