Employment History

Senior Software Engineer | Kazoo Games — Los Angeles, United States (Remote)

Oct 2023 – Present

8 Ball Champions — (iOS, Android)
- • Designed and implemented a trophy-based matchmaking system featuring dynamic search range, reciprocal pairing validation, and configurable min/max range interpolation based on player trophy count, balancing match fairness and queue times.
- • Responsible for adding 100+ unit tests, with some adding test coverage to Addressables asset grouping, being the most important ones, testing that only the bare minimum needed resources was actually embedded in final builds by crawling asset roots, helping to reduce download size from 220MB to 112MB.
- • Refactored the initialization process into a scripted initialization pipeline, improving maintainability and extensibility while simplifying the identification and debugging of step-specific issues. The new architecture also enabled automated timing benchmarks for all initialization stages.
- • Designed and implemented a Play FTUE flow that allowed players to begin gameplay while remaining remote assets were downloaded, reducing tap-to-game time by 50% (from ~60s to ~30s).
- • Designed and implemented device thermal control feature by flagging specific areas as important or semi important, so the target fps could be dynamically controlled depending on area importance and current device thermal state, which helped players to sustain longer sessions.
- • Implemented python automation scripts for development and LiveOps.
- • Added support for Apple Sign In.
- • Reduced store fetching times by redesigning the PlayFab store retrieval process to use concurrent batched requests, improving responsiveness without exceeding API throttling thresholds.
- • Enhanced network queue performance by introducing an opt-in request batching delay, reducing the number of backend calls generated by repetitive user actions while maintaining a responsive user experience.
- • Designed and implemented the Black Widow event leaderboard system, supporting player ranking, score tracking, and reward distribution.

Senior Software Engineer | Ten Square Games — Wrocław, Poland (Remote)

Aug 2021 – Oct 2023

Hunting Clash — (iOS, Android)
- • Designed and implemented a login content patching system that delivered only content model diffs during authentication, reducing login times and server bandwidth usage.
- • Designed and implemented a client-side prediction and server reconciliation system, significantly improving responsiveness for player actions such as purchases, animal upgrades and inventory management.
- • Designed and implemented the Helicopter Hog Hunting event, including gameplay systems, rewards, and event progression mechanics.
- • Designed and implemented the Pins & Patches collection feature, including collectible items, duplicate shop, profile showcase, and reward systems.
- • Designed and implemented the Wheel of Fortune feature, including server result mapping, rendering, effects and reward presentation.
- • Designed and implemented PvP Duel Leagues, including ranking systems, divisions, seasonal progression, and league-based reward distribution.
- • Designed and implemented the Radar power-up, enabling automatic selection of the highest-value animal from available targets with cached animal respawn queue system.
- • Identified and resolved memory leaks, improving application stability and reducing ANRs, especially on low-end mobile devices
- • Reduced client-server payload sizes by approximately 40% by replacing JSON-based communication with Protocol Buffers (Protobuf), improving responsiveness and reducing packet fragmentation (Maximum Transmission Unit).
- • Added gameplay, economy, and feature-specific analytics events across nearly all delivered features, enabling Business Intelligence teams to monitor player behavior and make data-driven decisions.
- • Collaborated closely with LiveOps, game designers, backend engineers, artists, QA, and Business Intelligence teams to design, implement, and deliver live game features and content updates, ensuring content schemas were validated and aligned with operational requirements.

Heavy Metal Machines — (PS4, PS5, X1, XSX, PC)
- • Contributed porting the game from a PC-only (Steam) to PlayStation 5 and Xbox Series X/S, ensuring compliance with platform certification requirements (Sony TRCs and Microsoft XRs).
- • Profiled on PS5/Razor and Xbox/PIX (WinPixEventRuntime), finding and fixing performance bottlenecks, contributing to improved stability and overall system performance.
- • Designed, implemented and integrated FMOD audio wrapper into last gen consoles.
- • Responsible for refactoring legacy UI built with NGUI to Unity UI (UGUI), adopting reactive programming patterns using UniRx to improve code clarity.
- • Added several analytics events (Power BI) helping the team make data-driven decisions.
- • Maintained a Domain-Driven Design (DDD) architecture by modularizing features into independent assemblies, improving compilation times and enabling more efficient patching workflows.
- • Maintained a clear separation between presentation and business logic by isolating Unity-based view components from core logic implemented in pure .NET projects, relying on dependency injection (Zenject) to achieve high testability and maintainability.

Space Mavericks — (iOS, Android)
- • Developed enemy AI systems using behavior trees, implementing enemy decision-making, combat behaviors, and state-driven actions.
- • Built spaceship and projectile movement physics, including interactions with multiple gravity bodies/planets and fully predictable trajectories used for gameplay mechanics and power-ups.
- • Designed and implemented heat-based combat system, featuring four ship abilities: shield, light attack, heavy attack, and ultimate, with heat acting as a core gameplay resource.
- • Implemented destructible planet systems, supporting real-time planet destruction as part of core gameplay.
