I take things out
of other people's
hot paths.

11 of my changes are merged into OpenTelemetry, which is how most of the cloud watches its own software, and which finished graduating from the Cloud Native Computing Foundation on 11 May 2026. 10 more are open right now and being reviewed by the people who maintain it.

gthe 421 blocks on the floor are one real commit. push them around, then collect them.

Every block on the floor is one of those 421. Press g and the 2 that survive stay behind. Nothing on the page labels them, but they are the only 2 that never stop moving.

This is the closest thing I have to a job history.

So it goes where a job history would. These 10 open ones are the best code I have written. None of them are merged yet, so read the numbers and decide for yourself.

Merged

03projects6 things I built

Sherlock

Go

Reads raw Bitcoin block files and works out which addresses probably belong to the same person, from patterns like which coins got spent together. Writes up what it found.

itssaharsh/sherlock

Coin Smith

Go

Builds Bitcoin payments that follow the shared standard. Picks which coins to spend, works out the fee, and handles change without leaving amounts too small to ever move again.

itssaharsh/coin-smith

Chain Lens

Go

Opens a single block and reports everything inside it: every payment, what it cost, how big it was, and which kind of spending rule it used.

itssaharsh/Chain-lens

YouTube Shorts Pipeline

Python

Writes the script, finds the footage, and publishes the video, on a schedule, without anyone touching it.

itssaharsh/ed

Hydra Recall

Go

Memory for an assistant that understands time. Facts are stored with the window they were true for, so when something changes the old version is kept rather than painted over, and you can ask what was true on a given date. When it does not know, it says so instead of guessing.

private, happy to walk you through it

autoapply

Python

Finds job openings, tailors the application, and applies. Survives being killed halfway through without losing work or applying to the same place twice. Runs on your own machine by default, so nothing personal leaves it. Around 350 tests.
