Unreal Engine Gameplay Programmer (Contract) at Diaspora Games

Project Elemental: https://store.steampowered.com/app/2335890/Project_Elementals/ Handled most of the gameplay and core logic development, and created in-editor tools to accelerate other team members’ workflows. C++ • Developed and encapsulated core FPS mechanics, preserving upstream compatibility and simplifying future upgrades. Example: inherited Lyra’s weapon system and built first-person logic based on the parent weapon classes. • Refactored the project architecture to align with Epic’s Lyra standards, improving modularity, maintainability, and scalability. Example: migrated core logic (e.g., weapon instances, character classes) into C++ Source modules while keeping Blueprint layers clean and data-driven. • Implemented client–server replication for critical FPS actions such as shooting, reloading, and weapon swapping to ensure reliable synchronization in multiplayer matches. Example: integrated server-side rewind (lag compensation) to improve hit detection accuracy under high-latency conditions. • Extended Unreal’s Gameplay Ability System (GAS) by creating custom Ability Tasks (e.g., FP_PlayMontageAndWait) targeting specific skeletal meshes (such as FPS arm meshes), enabling first-person-specific animation playback. • Developed character abilities, in both C++ and Blueprints. • Integrated a dynamic cosmetics system that swaps character meshes and skins at runtime using modular C++ components loaded via Lyra Experience and Game Feature Data Assets. • Implemented new gameplay attributes (stamina, health, mana, elemental resistances) using GAS for scalable stat management, leveraging Gameplay Effects, Gameplay Tags, and Execution Calculations to handle additive and subtractive stat modifications. • Developed custom Unreal Editor C++ automation tools to accelerate repetitive Blueprint setup tasks which was a Game Designer's task. Example: built an in-editor tool that parses Excel configuration files to automatically generate and organize WeaponInstance Blueprint assets into their respective weapon folders. Blueprints • Implemented UI logic (HUD, health/ammo indicators) using Common UI, and bound gameplay events from GAS for real-time updates. • Set up FPS animation states (aim down sights, weapon sway, sprinting, reload) through Animation Blueprints and animation layers. • Prototyped and tested gameplay features in Blueprint before migrating finalized systems into C++ for performance and maintainability. • Implemented elemental ability VFX (flamethrower, frost breath) by combining Material Graph, Niagara, and Gameplay Ability System events, ensuring the FX timing and intensity dynamically respond to ability activation and character state.

Unreal Engine Developer at Gianty VN

GIANTY VN (Fulltime) Unreal Engine Developer Aug 2024- May 2025 Bastoi - Tekfall Supreme: for the security purpose I cannot directly show the project because the customer has not published it yet Project preview/introduction: https://www.youtube.com/watch?v=d47VDGbb1I8&t=81s Developed and maintained core systems using Unreal Engine 5, blending C++ and Blueprints for a highly modular and scalable architecture. C++: • Applied SOLID principles to structure and enhance the game's architecture for both single-player and multiplayer modes. • Implemented advanced Unreal Engine systems such as Gameplay Ability System (GAS) for complex combat mechanics, character progression, and abilities. • Created custom latent actions/tasks in C++ for Blueprint usage to handle timing, asynchronous workflow. • Designed and integrated UI systems, including dynamic menus and HUDs, using UMG and Blueprint scripting. Blueprint: • Leveraged Blueprint Interfaces and Event Dispatchers for modular and scalable communication between gameplay objects. • Designed and integrate interactive UI elements using UMG and Blueprint scripting, including dynamic menus, HUDs, and in-game notifications. • Worked on Blueprint scripting for AI behaviors, animations, and environmental interactions, collaborating with designers to bring creative ideas to life. • Exposed C++ functionality to Blueprints, enabling game designers to work with complex systems easily without requiring direct code changes. • Optimized large Blueprint graphs by reducing complexity and ensuring maintainable structures, improving game performance and debugging workflows. ARPG game template: Developed action rpg game template based on Lyra, utilize Game Features and Modular Gameplay plugins, mainly use C++ (80%) and BP (20%) C++: • Wrote new arpg game core using C++ and Blueprint with Game Features plugin • Followed Lyra standard to make sure the source code modular and scalable in the future • Created new ARPG Abilities, Combo systems, that utilize the original source code of Lyra • Created new Attributes, Gameplay Effects with new GameplayEffectExecutionCalculation • Handled calculating and applying Damage • Utilized Gameplay Message Router plugin to update changes into UI Widgets. Blueprint: • Setup the Data Assets such as: Lyra Experience, Ability Set, UI Data set • Handled UI delegates to update Attributes when changes happen via Gameplay Message Router plugin as describe above
