Second Brain as RAG
A git-versioned Obsidian vault is the retrieval corpus. Routing rules, full-text (FTS5) search, and per-project memory pull relevant prior decisions into context on demand, so outputs are grounded and improve over time.
I'm Evan Stachowiak, and I build things. I grew up between two worlds: a mother with a doctorate in nursing education and a father who ran manufacturing companies. One side gave me a deep respect for understanding how things actually work; the other gave me an early, hands-on feel for how a business runs on the floor. My childhood was split between the suburbs and a horse rescue in Wisconsin, which mostly meant manual labor and weekends building and fixing things next to my dad.
One of those projects was a horse shelter. We built it by measuring the old one, working out every material and how the pieces fit, and turning that into a plan we could actually execute. That loop, understand the inputs, understand how it works, then build it, has never left me. A few years later, at 13, I watched my dad run gutters in a way that made no sense to me, suggested a cleaner method, and it worked. That was when I realized I had a knack for seeing how things should work, as long as I understood why they work first.
That curiosity runs through everything, not just code. I started college on a vocal performance scholarship, which is where I learned to drill a hard skill until it becomes automatic, before the build instinct won and I moved into tech. I learn the same way regardless of the subject: break it down to fundamentals, build a working understanding from the bottom up, then get hands on and learn the rest by making mistakes fast. It is how I taught myself to ski and snowboard in a day each and ended up instructing, and how I taught myself the stack for my EV Trainer and shipped it in under a week.
My edge is where that curiosity meets discipline. I came up through quality and operations work in manufacturing, which made me genuinely analytical and critical about how things get built. Pair that with a real passion for statistics, the kind that has me thinking in expected value at the poker table as readily as in my work, and my information-management coursework, and you get what I actually do well: build with AI and keep it reliable. As a data science intern I put that to work right away, catching several errors in a costing model in my first week and automating documentation that would have cost a small team a week of manual effort.
“The question is never whether I can build it. It is what to build next.”
Everything else I have built came from the same place: sports analytics tools, an autonomous AI agent that researches and writes my morning briefing, decision-modeling trainers. Find the leverage point, learn what I need, and sweat the details until it feels right. I care how things look and not just whether they work, and the same discipline that keeps me consistent in the gym is what keeps me refining a build long after it runs. At this point the question is never whether I can build something. It is what to build next.
Quant Edge Tracker
1200 x 800
A sports analytics platform that turns market lines into fair probabilities and tracks where the statistical edge actually lives.
Quant Edge Tracker is a data pipeline plus modeling layer for sports analytics. It ingests market lines, converts them into fair, vig-adjusted probabilities, tracks closing-line value over time, and surfaces statistical edges through interactive charts. The work is in the modeling and the data plumbing: calibration, sample sizing, and honest performance tracking rather than tips.
AI News Agent
1200 x 800
An autonomous agent that researches the day and writes my morning briefing before I am awake to read it.
AI News Agent is a self-running daily briefing. A hand-rolled agent loop gathers and ranks the day's news against a profile of what I care about, drafts a tight summary, and emails it on a schedule. It keeps persistent topic memory so the briefing sharpens over time, includes per-item Q&A and budget tracking, and was later rebuilt on Claude Code Routines and the Resend MCP.
EV Trainer
1200 x 800
A game-theory trainer that teaches expected-value thinking through interactive, voice-enabled decision drills.
EV Trainer is a decision-modeling trainer built on applied game theory. It runs expected-value and decision-tree analysis, computes ranges and equity, and turns the math into interactive, voice-enabled drills so the reasoning becomes second nature. It is an applied study in decision science and statistics, and I taught myself the stack and shipped the first version in under a week.
The system engineered around the AI. Not “I use AI,” but the retrieval, orchestration, and discipline that turn a model into reliable output on real projects.
A git-versioned Obsidian vault is the retrieval corpus. Routing rules, full-text (FTS5) search, and per-project memory pull relevant prior decisions into context on demand, so outputs are grounded and improve over time.
Every build runs discuss, plan, execute, verify, driven by machine-readable roadmap, spec, plan, and state artifacts.
A silent gap-check audits real knowledge; genuine gaps spin up a seminar of parallel research agents that investigate, debate, then a fresh agent synthesizes, before any code is written.
Work is delegated to specialized subagents (planner, executor, reviewer, verifier) running in parallel and in isolation, so large builds parallelize and the main thread stays focused.
context-mode sandboxes raw tool output in an indexed store (only summaries reach the window) and a live monitor hook warns before context fills, so long sessions do not degrade.
Lifecycle hooks enforce phase boundaries, scan reads for prompt injection, and validate commits before they run.
