PROFILE
Unity Developer with 4+ years of commercial C# and Unity experience. Build gameplay and UI systems, integrations, and
release-ready mobile products across R&D, production, and independent projects.

PROFESSIONAL EXPERIENCE
Self-Employed
C# Unity Developer | November 2025 - Present | Ukraine
● Delivered independent Unity projects from concept to publisher-ready builds, owning gameplay architecture,
implementation, integrations, and release preparation.
● Designed an endless-level generation algorithm that guaranteed solvable arrow-puzzle layouts, prevented invalid
configurations, and controlled difficulty progression.
● Implemented responsive gameplay feedback across animation, tweening, particles, camera shake, and audio, making
player actions and state changes immediately clear.
● Applied AI-assisted workflows to research, implementation support, debugging, visual ideation, and market analysis while
retaining ownership of architecture and code review.

KEVURU Games
C# Unity Developer | March 2023 - November 2025 | Ukraine
● Refactored a 1,000+ line monolithic class responsible for server-data processing into smaller modules, improving
maintainability and helping identify and resolve a complex data-handling bug.
● Designed and implemented the project's foundational screen and popup system, establishing a reusable UI framework
where no structured UI system previously existed.
● Adapted to an NDA-protected client's internal development systems and Perforce Helix workflow, investigating issues and
preparing technical findings for improvement.
● Represented the development team in client meetings during the Team Lead's absence, clarifying requirements and helping
align daily priorities across the team.

Smart Project Games
C# Unity Developer | February 2022 - February 2023 | Ukraine
● Developed gameplay systems for R&D projects, including a worker-management architecture for resource gathering,
transportation, processing, and task execution across multiple locations.
● Designed extensible worker behavior using abstract base classes and inheritance, allowing new worker roles and task flows
to be added without duplicating code.
● Developed gameplay systems integrated with backend services through REST APIs.
● Integrated project content with an existing internal AssetBundle pipeline to load later levels, 3D models, and resources on
demand.
● Contributed to a 3D mining feature by implementing a dynamic drill-pipe system with mesh-based geometry and
movement-responsive physical motion.
● Collaborated with Technical Artists to align gameplay logic with visual implementation.

Raccoons Games
C# Unity Developer | August 2021 - January 2022 | Ukraine
● Owned end-to-end Unity development for a casual mobile game as the sole Unity Developer, from gameplay architecture to
release-ready delivery.
● Designed and implemented the core object-catching gameplay loop, including spawning rules, health consequences,
difficulty balancing, and responsive game feel.
● Built a balancing tool that made gameplay parameters faster and easier to adjust during iteration.
● Implemented main-menu flow, in-app purchases, advertising, and analytics integrations.
● Tested, debugged, and stabilized gameplay systems; documented them for future maintenance and handover.
