Personal knowledge tree

Foundations → applications → shipped proof.

I organise my work like a tree. The trunk is how I think and work. The branches are the capabilities and foundations I keep developing. The leaves are the actual things I ship: systems, repos, articles, demos, games, templates, and case studies.

The tree model

Trunk

The operating philosophy: learning by building, moving from fundamentals to systems, and turning work into public knowledge assets.

Open Trunk →

Branches

Foundational branches explain reusable principles. Applied branches show where those ideas become useful in real products and systems.

Open Branches →

Leaves

The visible proof: repos, articles, games, demos, devlogs, reels, diagrams, templates, and case studies.

Open Leaves →

Foundational branches

These are durable knowledge branches. Each concept is explained once at the foundation level, then linked outward into applied work.

Math & Arithmetic

Numbers, geometry, trigonometry, vectors, probability, graphs, optimization, and systems math.

Explore Math →

Physics

Motion, forces, energy, waves, heat, electricity, magnetism, fluids, and systems behaviour.

Explore Physics →

Computer Science

Data structures, algorithms, state machines, networking, distributed systems, security, and architecture.

Explore Computer Science →

Electricals & Electronics

Circuits, signals, timing, sampling, filters, sensors, microcontrollers, communication, and embedded interfaces.

Explore Electronics →

Applied branches

Game Development

Movement, combat, collision, networking, procedural systems, balancing, and playful interaction design.

See related leaves →

AI / Infrastructure

RAG systems, inference platforms, observability, release safety, queues, cost controls, and operational readiness.

See related leaves →

Platform Engineering + DevSecOps

Cloud delivery, IaC, CI/CD, auditability, security fundamentals, and production reliability.

Case studies →

Hardware + Embedded Systems

Physical interfaces, operator stations, controls, arcade systems, homelab rigs, and embedded experimentation.
