How I work

How I work.

Four steps from first call to release. No surprises on deadlines.

PHASE.01

Discovery

I dig into the game/feature: genre, target platform, tech constraints. Leave with an estimate in hours.

PHASE.02

Architecture

I lay down patterns: State, Strategy, ECS, DI. Document the data flow. Easy to build features after.

PHASE.03

Production

Iterative: feature → playtest → fix. Regular builds, clean git changelog.

PHASE.04

Polish & Ship

Game feel, shaders, optimization, profiling. Build release, SDKs, monetization, analytics.
