I'm Chase, a Senior Software Engineer with 10+ years of experience owning full-stack systems across multiplayer games, cloud backend infrastructure, and developer tooling. At my most recent role, I was the sole engineer accountable for an entire live multiplayer game's technical stack - client systems, dedicated server infrastructure, backend APIs, database architecture, CI/CD pipelines, and live operations - effectively filling six specialized engineering roles simultaneously.
I don't just contribute to systems. I own them end-to-end, from initial architecture through production stability and live deployment. My background spans Unity/C#, Azure/AWS, MongoDB/Redis, multiplayer networking, platform integrations (PlayFab, Epic Online Services, Steamworks, Easy Anti-Cheat), and backend API design. I've shipped production systems at Blizzard Entertainment on StarCraft II and led all engineering on a live multiplayer title at tinyBuild.
I take on hard problems independently, communicate clearly across technical and non-technical teams, and deliver systems that hold up under real-world load.

Looking for an animator who understands both the artistic side and the production side of animation?
I help clients create smooth, production-ready animations for games, trailers, explainer videos, and animated content.
My main services include:
• 2D Motion, Animation (Moho, After Effect)
• Spine Animation for Games
• Motion Graphics & Explainer Animation
• 3D Character Animation (Maya)
• 3D Game Animation
• Rigging & Animation Workflow Support
Unlike many animators who focus only on making an animation look good in a portfolio, I pay close attention to how the animation will actually be used inside a game, video, or production pipeline.
For game projects, I understand the importance of:
• Clean animation loops
• Responsive combat and movement animations
• Export-ready Spine and Maya files
• Optimization for real-time engines
• Clear communication with programmers and game designers
For video and motion graphics projects, I focus on:
• Strong timing and spacing
• Appealing character performance
• Smooth transitions
• Clear visual storytelling
My background includes working with Maya, Spine, Moho, Substance Painter, and game animation workflows. I have experience creating character animations, cinematic sequences, gameplay animations, and animated content for both academic and freelance projects.
What clients usually appreciate most is that I communicate clearly, respond quickly, and treat feedback as part of the process rather than a problem.
Whether you need a single animation or long-term support for your project, I'd be happy to discuss your goals and see how I can help.
Feel free to send me a message and tell me a little about your project.

I am a top rated freelancer and have been making games since 2010, mostly with C++, Game Maker, and Unity.
Since 2013 I've worked for various clients here on Upwork (was called oDesk back then).
The work I did for some of my clients involved having to learn new programming languages, these feature my flexibility.
I recently made around 50 HTML5 games for an online school based in Australia - you can try eight of those for free
I am particularly good at making rough game concepts into fully playable games, and can do that very quickly if the clients allows me to use Game Maker:Studio 1 or 2 for the job.
I can also make small coding projects in programming languages I've never even used before if given enough time.
I also do robotics and general automation with Arduino and C++ in my spare time.
Even more recently I've started taking AI training data annotation and quality control tasks for both image generators and large language models - in particular code review for LLM training.
I've also started teaching Game Maker:Studio lessons.
These are the products that I have developed for my clients:
*Android - games, other apps
*HTML5 - games, other apps
*iOS - games
*Windows - games, tools, scientific simulations
*Game Maker Studio 1 & 2 extensions (C++, javascript)
*Apps and games in programming languages that I haven't learned prior to taking on their respective jobs
*Autohotkey scripts for remapping keys and general automation
*Python image processing tasks
