• • Became quite proficient debugging Power PC assembly code

Game Experience

• Integrated a Flash UI middleware product on PC, PSP, and Xbox versions of the engine
• • Wrote PSP UI rendering code from scratch
  • Hooked the middleware product into the engine's memory management system
  • Integrated Flash into the tool chain so that it is automatically stripped and packaged for the engine
  • Worked with UI design team to ensure UIs fit within memory and needed features were properly supported
• Worked with artists to implement rendering bug fixes on the PSP and implement new functionality to conform with existing PS2 rendering code

• Created a symbolic story representation based on the concept of locks and keys
• Formulated story elements as keys with preconditions and resultant outcomes
• Implemented an A* search to satisfy the story goals as set forth by a designer

• Implemented additions to the navigation system for teleporters and jump-pads
• Created a sensory perception system for items currently within the bots' view
• Developed a memory system for player and item locations containing a confidence metric

• Implemented coordinated squad attacks for enemies carrying shotguns, machineguns, and rocketlaunchers
• Developed behaviors for shotgun toting enemies that hound the player and move to cover in order to reload
• Developed behaviors for machine gun enemies that prefer taking pot shots from cover and will move from one cover spot to the next in order to flank enemies
• Produced a riot shield enemy that provides moving cover for shotgun and machine gun enemies

• Programmed many of the core subsystems such as skating physics and rail grinding
• Organized team to meet milestones set forth by the producer
• Directed artists, level designers, and programmers to produce a singular vision
• Coordinated between other team leads to setup gameplay testing schedule and bug feedback/tracking systems
• Worked on creation and updates of game documentation: Concept Document, Game Design Document, Technical Design Document, Level Design Documents, Art Style Guide, Asset and Development Plan

• Implemented a 2D physics simulation using a particle constraint system which included rotational dynamics
• Created a graphics engine utilizing only Windows API and custom blitting (alpha blending, parallax scrolling)
• Optimized sprite rotations using indexed pre-rotated sprites because hardware acceleration was not desirable

• Wrote a grammar and lexical analzyer for the language
• Implemented a parser to create a syntax tree from the token stream
• Built a compiler to output bytecode from the syntax tree
• Created a virtual machine to run the language

• Utilizes a uniform way of rendering regardless of underlying API
• Loads BSP: lightmaps, diffuse texture, ray casting, PVS
• Renders large scale terrains using a patch based lod approach
• In-engine terrain editor: variable sized brushes, terrain splatting, quadtree subdivision
• Features: ARB shader language, HLSL, Particle Manager, 3DS Loader, LDM (custom mesh format), skeletal animation
• Implemented and tested a math library which includes vectors, quaternions, matrices, bounding volumes, and intersection tests

• Modified the Doom 3 FPS style gameplay to an tactical overhead style gameplay similar to Alien Swarm
• Created point and click system in which the player could issue commands to AI squad mates using menus

• Created a lexical analyzer, abstract syntax tree, and parser for a given grammar
• Developed an intermediate representation tree with associated interpreter
• Wrote an optimizer which utilized peephole optimizations, common subexpression elimination, and smart register allocation
• Built a compiler that output MIPS assembly
