Interactive Ukrainian-language stories with branching choices and character customization. I developed narrative components, product features and the mobile optimization work described below.
Problem
The build exceeded 200 MB. With three stories available, freezes and crashes occurred after 3–4 chapters of a story.
Solution & my contribution
Developed custom Naninovel scenario components; integrated sound, animation, analytics and supporting services.
Result
Source-reported result: iOS build 41.7 MB; Android build 48.2 MB. Seven stories were added: all 10 stories, with 4–13 chapters each, could be completed in one session without freezes or crashes. These are historical project observations, not a new benchmark.
A family of social-network bubble shooters. All five historical titles are preserved below; the source describes a shared contribution rather than separate ownership of each game.
Problem
A publicly shared Cheat Engine exploit let players alter special resource amounts.
Solution & my contribution
Worked with the backend developer to analyze the attack, change sensitive-data storage and transport, introduce server validation and protect values on the client.
Result
After the update, the existing cheat stopped working. This is the documented outcome of that incident, not a claim that all cheating was eliminated.
