Khôi Nguyên / TOHICAN
Music arrangement, audio post-production, and game audio systems.
Six years in audio production, film, games, and animation - now extended into Lua runtime systems, competition-aware music engines, and reverse-engineering work for SP Football Life 2026.
One portfolio, two strengths
Creative audio taste backed by engineering discipline.
The original deck positions TOHICAN as a music arrangement and audio post-production specialist. The FL26 work adds a sharper technical proof layer: real runtime systems, hard bug fixes, evidence-first debugging, and release engineering. This site merges both into one hiring portfolio.

Audio systems built under real game constraints
These cases turn the audio background into systems work: Lua hooks, runtime state, binary formats, memory research, and release gates.
Shipped v2.0.4Lua runtime
IntroServer v2
Match cutscene engine
Routes pre-match, half-time, full-time, and award-ceremony cutscenes per competition and derby.
Hardest problem: five modules fought over one engine-owned video slot. The fix partitioned ownership by broadcast phase and proved the related roster-overlap bug across all 88 competitions.
- Coverage
- 88 competitions / 46 derbies
- Architecture
- 3-layer, 5-module Lua routing
Shipped v1.1.0Music engine
SoundtrackServer - TOHICAN Edition
Competition music routing
Auto-detects competitions and plays matching menu, career, edit-mode, and results-screen music.
Hardest problem: the ID3 reader used the wrong MP3 frame-size math. I rewrote it for 7-bit synchsafe decoding and validated 432 MP3 files.
- Scale
- ~7x upstream coverage
- Proof
- Full shipped asset validation
Lab-provenMixer
SoundServer Auto-Duck
Event-driven audio mixer
Fades music during highlight windows, then restores without the player touching a slider.
Hardest problem: filename-gap heuristics flickered because video streams arrive in chunks. A one-shot event marker replaced file-activity guessing.
- Lifecycle
- selected -> active -> restored
- Method
- Event marker over inference
Internal R&DReverse engineering
dt18 Gameplay Layer
Binary and memory research
Tunes tempo, ball weight, shot power, and reaction speed by reading binary constants and live memory.
Hardest problem: decoded a proprietary zlib container without a public spec and traced a live pointer chain for simulation tick rate.
- Work type
- Container decoding + pointer tracing
- Outcome
- Controlled match feel
