Planned Pixel Studio
Legacy replacements, security testing and AI research built from first principles.
01 / What I do
Access databases, claims viewers and directories rebuilt as maintainable web apps, with the old behavior intact.
Help desks, forgotten endpoints and unwritten assumptions: the doors attackers actually use.
Reinforcement learning, simulation and optimization, written without high-level libraries.
02 / The workshop
Machine learning
NEWHierarchical reinforcement learning in a grid world. A manager agent picks sub-goals, a worker agent walks there, and together they learn to fetch a log, build a bridge and get home. A “profit-sharing” reward keeps their goals aligned.
Security tooling
NEWCaller verification for IT help desks. Before anyone resets a password or MFA, the caller reads a live 6-digit TOTP code off their phone. Facts leak. Possession doesn’t.
Healthcare · legacy replacement
NEWA Django rebuild of a legacy healthcare claims viewer. Reads EDI 837 claims and renders print-accurate UB-04 and CMS-1500 forms, with PDF, Word and CSV export.
| Squared-SquaresNEW | Kaggle’s Squares in Squares competition: for every n from 1 to 1000, fit n unit squares into the smallest possible square. Scoring tools, a certified per-n merge pipeline and my own packing searches. | 2026 |
|---|---|---|
| ShrimpleNEW | A tiny pixel-art shrimp that lives in your Windows system tray and reminds you to sit up straight. No sounds, no pop-ups, just a shrimp. | 2026 |
| Logarithmic-Hamming-NumbersNEW | Finds the nth Hamming number, 2ⁱ·3ʲ·5ᵏ, by counting lattice points under a plane in log space, instead of generating every number before it. The billionth, all 844 digits, takes about 11 ms with its C extension, and the 10¹⁶th takes under two minutes. | 2026 |
| Window-WorksNEW | An interactive office floor plan. Look up your seat, reserve a free desk, and let admins repaint the layout without touching the database. | 2026 |
| Employee DirectoryNEW | A company directory built over a legacy Microsoft Access database, sorted by department and hierarchy, with birthdays and work anniversaries on the front page. | 2026 |
| Normalization SimNEW | An agent-based toy model of what happens when AI pulls everyone’s opinions toward the mean. Tracks stability, Gini inequality, opinion diversity and trust over time. | 2025 |
| Sprite-MapperNEW | Upload a sprite sheet, click a tile, get its coordinates. No more counting rows and columns by hand. | 2025 |
| Fruit ClassifierNEW | A single-neuron network in pure NumPy that tells limes from lemons by weight and color. Sigmoid, backprop and gradient descent, all by hand. | high school |
03 / About
In high school I wrote a single-neuron network and reworked Karpathy's min-char-rnn to show off to classmates. I also co-led the programming club and consulted on my state's first high-school cybersecurity curriculum.
In college I spent two years on computer science and math, and started the ML/AI Special Interest Group. There were no undergraduate ML courses yet, so we broke the topics down in plain English, with no high-level libraries.
These days I run Planned Pixel Studio, and on my own time I experiment at the edges of AI research, like agents that learn to share profit. I think there are far more interesting, world-altering things to do with AI than chatbots.
Partners: Makoons Technologies for robust, scalable engineering, and Primagery for CRM, identities and brands.
