A PERSONAL ENGINEERING NOTEBOOK
Curiosity,
running in
production.
Exploring the space between AI, data, infrastructure, and simracing. I build things, measure what happens, and share what I learn.
01 / SELECTED WORK
From idea to working system.
SIMRACING / WHERE MY AI JOURNEY STARTED
From racing lines
to lines of code.
GT7Tracks was my first AI project. Alongside GT7Proxy, DashX2, and console-game plugins for SimTools, it connects a love of racing with building useful tools.
Explore simracing ↗02 / FIELD NOTES
The details behind the build.
PROJECT DEEP DIVE
RAG Gateway: from documents to cited answers
A shared retrieval pipeline connecting familiar AI clients, MongoDB Atlas, and local generation with Ollama.
PART I / BUILD & OPERATIONS
Building a tiny MongoDB cluster on Turing Pi RK1
Part I: four ARM nodes, Ansible automation, monitoring, and the lessons of operating a compact MongoDB replica set.
PART II / MEMORY & MEASUREMENT
MongoDB memory on ARM64: THP, TCMalloc & WiredTiger
Part II: controlled THP experiments, two dataset sizes, and what the evidence says about memory and concurrency.
03 / THE HOMELAB
A small lab.
Room for big experiments.
A place to connect the dots between databases, AI, and the systems underneath. Explore the ideas and lessons behind the lab.
