Source

Engineering excerpts with context and proof.

A focused view of public-safe source: what each excerpt proves, why the decision matters, and where the public repository is available.

hstephan23/dep_graph

DepGraph / TypeScript

Shows how dependency analysis becomes editor-visible feedback instead of a detached report, proving practical codebase-analysis judgment.

Maps graph findings back to file URIs so the signal appears in the developer's normal editor workflow.
Uses reach percentage as an explainable risk indicator, which makes the warning reviewable instead of vague.

hstephan23/2D_shooter_looter

Shooter Looter / C++

Shows a gameplay frame order that keeps input, pickups, weapon state, enemy behavior, projectiles, collisions, room transitions, extraction, and rendering in deliberate phases.

Uses an explicit C++/raylib frame pipeline so gameplay systems have predictable ownership and ordering.
Separates player input, pickups, weapons, enemies, projectiles, collisions, extraction, feedback, and rendering, which makes bugs easier to isolate.

hstephan23/retro-gaming-project

Retro Game / C

Shows clear C system boundaries in a real loop: input, timing, rendering, multiplayer branching, and shutdown all remain auditable.

Keeps timing, movement, rendering, and state application visible in one auditable control flow.
Calls shutdown explicitly after game-over rendering, which proves attention to lifecycle cleanup in lower-level code.
