Complete the work holding your game back

For studios, publishers and agencies with an existing Unity project and a specific task. A scoped engagement that lets your core team focus on developing the product.

Unity game optimisation

The game is too large, loses frame rate, freezes or uses too much memory on target devices.

I analyse build contents and performance, identify the causes and implement fixes in your project. I verify the effect in agreed scenes, on selected devices and in defined scenarios.

Outcome

Before-and-after build size and performance measurements, project changes, a verified build and a description of the achieved effect.

Build size, frame time and memory targets are defined after reviewing the project.

Discuss your task

Technical tasks before release

Bugs, unstable builds or unfinished integrations are delaying a release or update.

I take an agreed list of issues as a scoped engagement: reproduce bugs, fix their causes, integrate changes and verify affected scenarios.

Outcome

The agreed task list completed, a working build, verification results and documented remaining limitations.

Scope and timelines are estimated after reviewing the project materials.

Discuss your task

Mobile or WebGL adaptation

Your game needs preparation for another platform, while the core team is busy developing the product.

I adapt controls, UI, builds and agreed SDKs. I check launch, saves, core gameplay scenarios and platform constraints.

Outcome

A version for the agreed platform, project changes and materials your team can use for ongoing maintenance.

Platforms and integrations are agreed in advance; additional scope is estimated separately.

Discuss your task

Diagnostic fees are agreed after a brief discussion. Development cost and timelines follow a review of the scope.

03 / How it works

An agreed milestone in your project

  1. 01

    Discuss the task

    Briefly review your project, task, platform and constraints.

  2. 02

    Investigate if needed

    If scope is unclear, carry out standalone paid diagnostics with measurements and a plan.

  3. 03

    Agree on the milestone

    Define the outcome, timeline, cost, acceptance criteria and payment terms.

  4. 04

    Integrate and verify

    I implement changes in your project, check affected scenarios and share verification results.

  5. 05

    Hand over the result

    Provide code, a build and the agreed materials for your team. Discuss continued work.

I use AI to speed up development. I take responsibility for understanding your project, making technical decisions, integrating changes and verifying them against the agreed criteria. You receive a result your team can accept and continue to maintain.

Work is carried out under a contract. Scope changes are estimated separately. Additional specialists are brought in when needed.
