AI Systems
Agents and AI systems that do real work — measured, tested, and kept boring where it matters.
EFFNINE
AI · ENGINEERING · RESEARCH
Independent engineering, built one experiment at a time.

01 · WHAT I BUILD
Four things I build.
/02
Engineering Tools
Tools for building: context, memory, and automation for how I actually work.
/03
Research
Questions I'm chasing — evaluation, behavior, and where systems fail in the wild.
/04
Infrastructure
The plumbing between things — edge services, tooling, and small systems that stay up.
02 · SELECTED WORK
Things I'm building.
Atlas
exploringSystems design and engineering research — where I work problems through before they become tools.
CodeBro
buildingAn engineering context and memory layer for AI coding agents — verified facts, decisions, and impact analysis for a codebase. I use it daily.
EB — EffNine Benchmark
experimentalMeasuring how AI systems handle engineering-scale tasks. Early, rough, and getting more rigorous.
03 · ABOUT
A lab of one.
EffNine is my workshop — a one-person engineering lab for AI systems, tools, and research that interest me. Some things ship. Some become daily tools. Some are experiments that escape the lab. Everything is built to be simple, durable, and understood.
No investors, no roadmap theater, no noise. Just engineering I want to do, done properly.
