/01
AI Systems
Applied AI systems and agents — evaluation, tooling, and production integration that behaves predictably.
EFFNINE
AI · ENGINEERING · RESEARCH
EffNine is an independent technology lab — building AI systems, engineering tools, and research in the open.
01 · WHAT WE BUILD
Four lines of work.
/02
Engineering Tools
Developer tools that make complex engineering work simpler, faster, and easier to reason about.
/03
Research
Open research into intelligence, evaluation, and how AI systems behave when they leave the demo.
/04
Infrastructure
Small, sharp infrastructure — edge services, tooling, and the plumbing between systems.
02 · SELECTED WORK
Selected work.
Atlas
researchEngineering research and systems design. A space for durable work in progress.
CodeBro
in developmentAn engineering context and memory layer for AI coding agents — verified facts, decisions, and impact analysis for the codebase.
EB — EffNine Benchmark
in developmentA benchmark initiative for measuring how AI systems perform on engineering-scale tasks.
03 · ABOUT
A small lab for serious work.
EffNine is the independent lab space of a solo engineer. It exists to build useful AI systems and engineering tools, run research, and document the work — with a bias toward simple, durable, well-crafted artifacts.
No investors, no roadmap theater, no noise. Just engineering, research, and things that keep working.
