- Performance engineering: optimization, memory leak fixes, network ownership control
- Robust data architecture: DataStore design, save & progression systems

FAQ
What do you need from me to get started?
A clear description of what you want, any references or examples, and access to your game file if it already exists. The more detail you share, the faster and more accurate the result.
Do you offer support after delivery?
Yes. If something related to my work isn't behaving as expected after delivery, message me and I'll fix it. Revisions are included according to your package.
Do you work with my existing game or only new projects?
Both. I can add new systems to your current game or build from scratch. Just share your place file or a copy, and I'll integrate everything cleanly without breaking what you already have.
Will the code be secured against exploiters?
Yes. I use server-authoritative logic so critical actions are validated on the server, not the client. This keeps your game protected against the most common exploits and remote-based cheating.
Will I own the code and be able to edit it later?
Absolutely. You get full ownership of clean, commented and modular code, so you or your team can understand, maintain and expand it later without depending on me.
