A LITTLE ABOUT ME

Hello. I am Kenyan. a senior software engineer. an agentic engineer. a tool builder. an open sourcer. a coffee lover. Peter Etelej Emanikor.
I am a senior software engineer (currently @ Microsoft) building products end-to-end, from Go servers to desktop apps, and making AI agents genuinely useful along the way.
I care about simple systems, sharp tools and shipping things that work.

AGENTIC ENGINEERING

Empowering agents

I build MCP servers that empower AI to do more: largefile, diffchunk and others.

I build the tooling

Agent review surfaces (WorktreeView), semantic search for AI assistants (directory-indexer) and other open tools.

Trust, earned

Agents earn trust the way any contribution does: tests, builds and a multi-lens review before it merges.

Leverage, safely

Many bounded agent tasks: tight scopes, real guardrails, small blast radius and fast feedback.

ETHOS

Simplicity wins

The simplest thing that works is usually the right thing. Boring, proven tech where it matters.

Sharp tools over heavy process

Invest in the tools, and the work gets done. A well-made CLI beats a meeting.

Ship small, ship often

Small increments, fast feedback. Leave the codebase better than you found it.

Own it end-to-end

Design, code, deploy, run. Take responsibility for the whole thing, not just your slice.
