I build and analyze complex systems, then prove how they work with demos, diagrams, source-level notes, and clear limits.

Experiments Lab

BeserkBot runtime clips.

One runtime build, one live demo, four clips, and the plugin boundary spelled out. The other project pages carry the rest.

Rocket League Plugin Runtime

BeserkBot

Problem: Real-time plugins need fresh state, stable timing, and prediction math that survives latency.
Built: A Python plugin layer for CarbonX that exposes trajectory, timing, and runtime-control behavior to the AI player.

Build work

What I build.

Practical scopes for web apps, runtime systems, and security notes. Each one ends with something reviewable: a map, a trace, a report, or a shipped build.

Web apps with auth

Next.js apps with server-side checks, route boundaries, and clear deployment notes.

API boundary map
session and role checks
ownership review
ship-ready deployment pass

LeadGen is the reference build: webhook boundaries, account-state changes, and local review data kept visible.

Runtime tooling

Tools that make event order, state changes, and fallback paths easy to see.

event sequence notes
state-machine review
failure trace
runtime proof clips

Herald and BeserkBot show the shape: routing stages, rollback paths, latency-sensitive prediction, and explicit ceilings.

Open Herald

Security reports

Reports that separate proof, impact, assumptions, and fixes.

asset scope
deterministic reproduction
impact boundary
remediation path

14 research notes are organized on the security page. bxenc adds the tooling side with crypto choices and limitations shown plainly.
