• Blueprints Visual Scripting – A powerful node-based system that allows developers to create complex game logic without coding.
• C++ Programming – Offers deep customization and performance optimization through C++ scripting.
• Physics and Destruction – Includes Chaos Physics for realistic interactions, soft body physics, and destruction simulations.
• Multiplayer & Networking – Built-in support for dedicated servers, replication, and multiplayer features.
• Open-World Support – Designed for large-scale worlds with streaming, dynamic level loading, and procedural generation tools.
• Cross-Platform Development – Supports PC, consoles (PlayStation, Xbox, Nintendo), mobile (iOS, Android), VR/AR (Meta Quest, Vive, HoloLens), and even web-based applications.
• MetaHuman & Digital Humans – Tools for creating high-fidelity human characters with lifelike animations.
• Integration with External Tools – Compatible with Blender, Maya, Houdini, Quixel Megascans, and other 3D tools.

As a Game Engine Programmer at Epic Games, I contributed extensively to the development of Unreal Engine 4, where I helped design, implement, and optimize various features, tools, and systems that are now central to the engine’s functionality. My role spanned multiple domains, including codebase architecture, UI systems, cinematic tools, and platform-level support, and my work significantly impacted the engine's flexibility, performance, and user experience.

Engine Codebase Re-architecture & Modularization

One of my primary contributions was in the reconstruction and modularization of Unreal Engine 4’s codebase. I worked on transforming the engine from a monolithic code structure to a more modular system built around plugins and individual modules. This shift improved the flexibility, scalability, and maintainability of the engine, enabling Epic Games to more efficiently iterate on future features and improve the engine’s performance across different platforms. The new modular structure also allowed developers to integrate custom features and optimize the engine for specific projects without compromising the overall architecture.

Unified Settings API Development

I played an instrumental role in designing and implementing a unified settings API that was used across both the Unreal Engine Editor and game projects. Prior to this, managing settings in Unreal Engine could be complex, as it required handling multiple configuration files and settings systems. My work simplified this by creating a centralized API that streamlined the configuration process, ensuring consistency across both the engine and game projects. This helped improve workflow efficiency, reduced errors, and made the engine more user-friendly for developers working on a wide range of projects.

Sequencer Cinematic Toolset Development

I was involved in the initial development of the Sequencer cinematic toolset, an essential tool for creating cinematic sequences and in-game cutscenes. My work focused on transitioning Sequencer from a prototype to a production-ready framework. This included collaborating with other programmers to refine its user interface, functionality, and performance. I also contributed to enhancing its features, such as its ability to handle complex timelines, camera movements, and animation sequencing. As one of the core tools in Unreal Engine’s cinematic workflow, Sequencer now enables developers and filmmakers to create high-quality interactive and non-interactive cinematic experiences.

Slate UI Framework Enhancement

As part of my work on Unreal Engine’s user interface, I was responsible for the revamping and extension of the Slate UI framework API. Slate serves as the backbone for Unreal Engine’s UI systems, and my work aimed to make it more flexible and customizable for developers. I added new features, optimized performance, and ensured that it could be easily adapted to different types of applications, from complex game editors to more lightweight UI components. This enhancement greatly improved the engine’s ability to create responsive and dynamic user interfaces, ultimately making Unreal Engine more accessible for both technical and non-technical users.

Development of the Unreal Engine Launcher Application

I contributed to the design and development of the Unreal Engine Launcher a crucial application for managing Unreal Engine installations, projects, and assets. Using the Slate API, I helped build an intuitive and user-friendly interface that allowed users to easily manage their Unreal Engine versions, access the Marketplace, and open or create new projects. The Launcher plays a key role in the Unreal Engine ecosystem, streamlining the development process for millions of users worldwide, and my contributions helped ensure its ease of use and functionality.

Technical Support for Licensees & Industry Partners

In addition to development, I provided on-site technical support for licensees and industry partners, ensuring they had the necessary resources and assistance to effectively utilize Unreal Engine 4 in their projects. This included troubleshooting engine-related issues, assisting with feature implementation, and helping partners optimize their games and workflows. Through this, I gained deep insight into the needs and challenges of large-scale studios and indie developers alike, which helped inform future engine improvements and contributed to the success of Unreal Engine in various industries.

Second Life’s original legacy physics engine was plagued by griefing exploits and instability. To address this, I designed and implemented a physics abstraction layer using Havok, providing a robust foundation for gameplay interactions and environmental physics.

• Exploit Mitigation: Eliminated key vulnerabilities in the legacy physics system.
• Improved Stability: Enhanced collision detection and object interactions for a smoother user experience.
• Future-Proofing: Established a modular physics layer that could evolve with the platform.

I was a core member of the Windlight team, responsible for integrating advanced atmospheric rendering and 3D cloud simulations into Second Life. This was a significant graphical upgrade, elevating visual fidelity across the platform.

• Windlight Technology Integration: Adapted Linden Lab’s acquisition of Windlight and Nimble (originally based on Ogre3D) into Second Life.
• Realistic Lighting & Clouds: Developed real-time dynamic sky, weather effects, and improved atmospheric scattering.
• Graphical Enhancements: Made Second Life more immersive, setting a new visual standard for virtual worlds.

As part of the effort to modernize Second Life’s scripting capabilities, I worked on native scripting language improvements, laying the groundwork for future expansions.

• C# Scripting Prototype: Developed an early native C# scripting language for Second Life.
• Mono Integration: Helped transition Linden Scripting Language (LSL) into Mono-compatible functions, which later became the foundation for the Mono-based scripting system.
• Enhanced Developer Tools: Improved scripting efficiency, allowing users to create more complex interactions within the virtual world.

Second Life’s original viewer UI was built using the Mozilla framework, which suffered from performance issues and outdated design. I was instrumental in transitioning the client UI to a Qt/QML-based interface, making it more modern, responsive, and extensible.

• Qt Integration: Migrated the UI framework from Mozilla to Qt, improving performance.
• User Experience Enhancements: Designed a more intuitive, accessible interface.
• Performance Boost: Reduced client-side lag and improved rendering efficiency.

Beyond engineering contributions, I actively engaged with Second Life’s developer and user communities, helping shape the platform’s evolution through direct interaction.

• Bug Fixes & Issue Tracking: Addressed public bug reports via JIRA, ensuring timely resolution.
• Resident Feedback & Collaboration: Held weekly discussions with Second Life residents, gathering insights for future improvements.
• Mentorship & Onboarding: Assisted new users and developers in understanding Second Life’s tools and APIs.

My contributions to Second Life helped solidify its position as a leading virtual world platform, blending security, performance, innovation, and user-driven experiences. From server optimizations to graphical advancements and scripting innovations, my work played a key role in enhancing both the technology and the community-driven aspects of the platform.
