Hi, I’m
Shamli Sahani
Gameplay Programmer
I build gameplay systems with a focus on player
movement, combat mechanics,
and clean, scalable architecture using Unreal Engine (C++)
and Unity (C#).
Currently completing an MSc in Computer Games
Development at
Manchester Metropolitan University, United
Kingdom.
Previously shipped titles at Hunter
Games and GracyWoods.
Engineering Showcase
Extended standard UE5 movement to support wall-running. Uses raycasting and cross-products to calculate surface normals and apply counter-gravity forces.
Engineered a stalking AI using Environment Query System (EQS) for dynamic pathfinding in a changing maze. Implemented custom sensory perception logic.
Designed a complete combat loop with combo-chaining and ability cooldowns. Implemented an event-driven hitbox system for frame-precise melee interactions.
GracyWoods: Engineered a
conversational AI system and custom API layer before
transitioning to MSc studies.
Hunter Games: Successfully shipped
and maintained multiple live titles, focusing on
optimization and stability.
Professional Experience
- UI & Data Binding: Engineered a reactive UI layer for GenAI interactions, utilizing Lambda expressions and asynchronous callbacks to prevent UI freezing.
- Optimization: Conducted profiling sessions using Unreal Insights / Unity Profiler, reducing frame-time spikes by 30% through strict texture memory management.
- Shader Architecture: Optimized character rendering materials and shaders for mobile performance, ensuring visual fidelity within strict GPU budgets.
- Cross-Platform: Decoupled gameplay logic from the view layer (UI), ensuring systems scaled seamlessly across PC and Mobile inputs.
- Unity Architecture: Directed the full technical lifecycle for multiple hyper-casual titles using Unity (C#), owning system architecture from prototype to release.
- Memory Management: Eliminated runtime instantiation lag by engineering a robust Object Pooling system, significantly reducing Garbage Collection (GC) overhead.
- Event-Driven Systems: Implemented a C# Event / Observer pattern for the central game loop, allowing UI HUDs to update strictly on gameplay events.
- LiveOps: Managed the technical pipeline for content updates, ensuring 100% crash-free stability across 3 major version releases.
- Full Cycle Development: Delivered a complete Unity title from concept to Gold Master, implementing core physics mechanics and final UI polish within strict deadlines.
- SDK Architecture: Integrated critical third-party SDKs (Analytics, Ads, Auth), implementing defensive programming patterns to prevent main-thread blocking or crashes.
- Data Reliability: Engineered the local save system and cloud sync usage, ensuring 100% data integrity for player progression upon launch.
- Prototyping: Rapidly iterated on gameplay mechanics and UI flows based on design feedback, ensuring "Game Feel" was prioritized.
- Tools: Integrated third-party SDKs and external APIs to extend engine functionality, supporting the senior team in feature implementation and testing.
