Thirteen Agents in One Saturday.

I spawned 13 parallel Claude Code agents on a Saturday morning. Each shipped one feature for my trading system. Agent 12 overturned the hypothesis from Agent 1.

Most Second Brains Just Rotate.

88 concept articles, 301 sources, 13 agents. Most "second brain" stacks fail because they confuse output with compounding. Three Laws decide which yours is.

007 Engineering

I Renamed Seven AI Agents.

Animal names are debt. Functional names are leverage. The rename took 30 minutes and touched 26 files. Layer 1 vs Layer 2, and why naming is plumbing.

Five Cheap Fixes Took My Vault From 7.5 to 9.5.

A 90-minute lint pass: 19 missing banners, 132 unindexed notes, 24 confidence gaps, 6 open concept gaps, plus a contradiction scan. Whole pass, full receipts.

Win Rate Lies.

A 90% winner with a −1.04% expectancy. The Trojan Horse hiding in every sales pipeline — and the five-minute math that surfaces it.

A 3-weekend prospecting stack that replaced three subscriptions.

004 Workflow

Turning an Obsidian vault into an LLM-queryable knowledge base

Compiling a personal wiki so Claude answers from my actual notes — not training data. Karpathy's autoresearch loop, applied.

The AI sales stack I'd build if I started today

Four tools. Under $200/mo. Replaces what most AEs pay $2,000/mo for. The math, the workflow, the gotchas.

006 Forthcoming

Why outcome-based pricing wins the next AI cycle

ServiceNow's token tax. Sierra's per-resolution model. The pricing posture every AI vendor is converging on — and the one that breaks the seat license.

Hi, I'm Sachin.

I write about the infrastructure work between a chip and a quota — and I ship the AI tools enterprise GTM teams actually need.

Twenty years in enterprise software sales — Oracle and Salesforce in earlier chapters, most recent stint independent. Now building AI tooling for sellers, evaluators, and operators. Based in San Francisco.

This blog is a build log. Every post is a problem I hit, a tool I shipped, or a thesis I'm pressure-testing in the wild. No daily digest. No reposts.
