Software developer building backends and web products.
Subham Sahu — currently at Deloitte engineering insurance systems at scale. Previously: 3D manufacturing tooling, IVF teleconsultation, and a few side projects. Curious about AI tooling, agents, and the unglamorous parts of building software well.
01 / About
Three years building software, mostly for teams that ship.
I'm a software developer working at Deloitte on insurance systems — backend APIs, AWS pipelines, and the slow parts of modernizing legacy services.
Before that: 3D manufacturing tooling, IVF teleconsultation, and a handful of side projects. Curious about the unglamorous parts of building software well.

04 / Experiments
Small things, built for the love of it.
2025
01
shell-copilot
Zsh hook that pipes the last error plus a tail of history to Claude and prints the suggested fix inline. Lives in ~/.zshrc; ~200ms p50.

Mostly building. Sometimes experimenting.

Knowledge Context Graph
Retrieval that knows what's related, not just what's similar.
A graph-augmented retrieval system that ingests embedded data and builds a contextual knowledge graph over it. Multi-hop traversal, relationship-aware ranking, and context windows that compose rather than concatenate — because real context lives in relationships, not just embedding distance.

AI tooling
Working AI into the daily loop.
Cursor, Claude Code, Windsurf — wiring them into the way I build. Small agents to automate review and PRD-to-ticket work.
Reading
Re-reading DDIA, slowly.
Designing Data-Intensive Applications. Some books deserve a second pass. Currently between transactions and consensus.
Go
A second backend language.
Exploring Go for typing discipline, runtime simplicity, and lower-level control when Node feels too soft.
