Hi, I’m Sachin Chavan, a Software Engineer at ReasonSoftware based in Dubai, UAE.

I work across the stack, in Go, Node.js, Python, and React, with DevOps across AWS, GCP, Azure, and Oracle Cloud. My focus is cybersecurity, AI/ML, and blockchain, and I care a lot about clean systems, learning continuously, and self-improvement.

What I work on

Day to day I work in Go, Node.js, and Python, with React on the front end. A sample of my open-source work, across languages:

  • llm-relay, an OpenAI-compatible LLM gateway with provider failover (Go)
  • shodan, a CLI for interacting with the Shodan API (Go)
  • ethblock-store, an Ethereum block-detail store (Node.js)
  • turbo-fmt-println, a VS Code extension that automates debug logging (TypeScript)
  • mood-tune, mood-based music playback on the Spotify API (Go)
  • gitgrab, download individual folders from any Git repository (Go)

On this blog

I write about engineering across the stack, from backends and infrastructure to AI, cloud, and security, plus lessons from things that went sideways. The posts span the languages I actually use: Go in the llm-relay writeup, Python in the TurboQuant and multi-tenant RAG pieces, and Node.js in the distributed systems guide. If a post saves you from a mistake I made, it did its job.
