Hire the Best Game Developers in California

Hello! I'm Lucas. I am a highly experienced software developer who specializes in app and mobile game development, and I have been building apps, games, websites, and other software for over 15 years. I graduated with honors from the University of California: Santa Cruz with a degree in Computer Science (with a focus in game design). Upon graduating, I worked as an engineer for Intel for several years. After that, I decided to become an independent developer and have managed my own app development company for the past 9 years. I have developed and released several popular apps and games of my own design for Android and iOS, and have worked on countless projects on a freelance basis. These projects have ranged from small bug fixes/optimizations, to prototype designs of new games, apps and utilities, to fully functional apps for small studios and large corporations alike. Though I have focused expertise in mobile app and game developments, I am also quite skilled in related fields such as UI/UX design, web development, backend programming, and technical art creation (Adobe Photoshop/Illustrator/etc.). I am constantly learning new skills and work hard to keep my knowledge up to date with new frameworks, platforms, tools, and best practices. I have recently embraced agentic AI code development to speed up production time, but I never "vibe-code" or accept code changes without reviewing and understanding what has changed. AI is a valuable tool, but not a replacement for a professional developer. Don't waste your money on a bloated production team, and don't risk your dream project with an inexperienced or inattentive freelancer. Regardless of the needs of your project, big or small- prototype or production-ready, I'm your dev. Let's build it!

I'm one of the top social multiplayer game developers on Upwork. I only work with serious employers who are looking to make professional grade projects. If this is you, please get in touch with me and I'll provide you a list of my full portfolio for your review.

Hi, I’m Rick Santana — a Top-Rated game developer, 3D environment artist, animator, and technical artist with 15+ years of experience in real-time 3D, game environments, animation, video production, and interactive media. I help clients build, fix, polish, and optimize playable game worlds in Unity, Roblox, and Unreal. My work blends game development, environment art, level design, lighting, gameplay prototyping, technical art, cinematics, and optimization. I can help with: Game Development Unity gameplay systems, C# scripting, playable prototypes, first-person/third-person mechanics, UI/HUD setup, interaction systems, debugging, project cleanup, and build support. Game Environments Level design, terrain/world building, modular environments, asset placement, lighting, set dressing, optimization, LODs, collision setup, materials, and scene polish. VR / WebGL / Real-Time Builds Meta Quest VR scenes, WebGL prototypes, performance optimization, URP/HDRP setup, lighting optimization, asset cleanup, and build troubleshooting. Roblox Development Roblox Studio, Luau scripting, FPS systems, loadouts, weapon setup, animations, UI, multiplayer gameplay prototypes, and Roblox game systems.

My background started in multimedia, branding, animation, and video production before moving fully into game development and real-time 3D. That gives me a strong creative and technical mix: I know how to make a scene look professional, but also how to keep it clean, optimized, organized, and usable inside a real game project. Whether you need a polished Unity environment, a VR scene, a Roblox prototype, a WebGL build, a gameplay system, a cinematic trailer, or help fixing an unfinished project, I can jump in and help move it forward.

JOSH FOUNDER | 30 YEARS BUILDING AND SHIPPING SOFTWARE PRODUCTS I've founded studios, exited them, and shipped apps to both the Apple and Google app stores. Now I lead a US-based senior engineering team that directs AI agents across the full build. You get the speed. We stay accountable for what ships. This is not vibe coding. It is senior engineering judgment combined with AI execution, built for founders and operators who need to move faster without losing control of the codebase. We embed as a partner, not a vendor. Most clients stay and keep building with us as their de-facto tech team. WHY CLIENTS WORK WITH ME Many software and AI projects fail because the wrong decisions get made early. Scope is unclear. Architecture is rushed. Costs balloon. AI-generated code looks complete but breaks under real-world use. I help clients avoid that by putting senior technical judgment at the center of the build from day one: before development begins, before costs lock in, before the wrong decisions get baked in. WE'RE PROBABLY A FIT IF YOU Have a validated need but no technical team to build what comes next Have a spreadsheet or prototype that proved the idea but won't scale Have a vibe-coded app generating MRR but need a stable foundation under it Started building but need architecture and senior oversight to finish Want to use AI without losing control of your codebase Run knowledge-heavy operations you want to automate without losing human control WHAT WE DO: TWO SERVICE LINES, ONE ENGINE Every build runs on AI agents working alongside senior engineers. That engine powers both: Agentic Software Development. We build the product your customers use: apps, web platforms, games, AI products, and AR/VR, from MVP to scale. Agentic Workflow Automation. We automate the knowledge-heavy processes your team runs on: operations, data pipelines, and document workflows, with AI agents and human-in-the-loop control. The difference is simple. One builds the product your customers use. The other builds the process your team runs on. WHAT WORKING WITH ME LOOKS LIKE Full team: senior engineers, product owner, designer, and QA. I lead. AI executes. Nothing ships without senior review. Advisory: I come in as your fractional technical leader. Same judgment, scoped to what you need. Either way, your code stays clean. Your IP stays yours. We bill for outcomes and architectural judgment, not manual hours. REAL RESULTS Delivered a $1.2M-class enterprise platform for under $95K, same deliverables, fraction of the cost Designed infrastructure that scaled through 500% traffic growth post-launch, with no added admin staff Running 79M pricing combinations in the first 30 days of live production, a lifetime of manual work Drove a 70% increase in R&D utilization through higher AI adoption Turned 20 years of institutional knowledge into a single searchable, trusted source WHAT WE'VE BUILT Maritime AI (Dolgo): voice-first RAG platform for offline expert knowledge capture Automotive SaaS (Ben's Best Price): 79M real-time pricing combinations, replaced manual ops Chemical R&D (Private): 70% increase in AI usage, faster project completion Live Broadcast AI (Pickford AI): first-of-its-kind multi-agent storytelling engine with real-time audience adaptation Nonprofit / Education (5 Keys): 20 years of institutional knowledge made searchable TECH STACK AI/ML: LLMs, RAG, vector search, multi-agent, computer vision Mobile: React Native, Swift, Kotlin, Flutter Game/AR/VR: Unity, Unreal, ARKit, ARCore Backend: Python, Node.js, C#, Firebase, PlayFab Cloud: AWS, Azure, Google Cloud, Supabase, Docker, Kubernetes BEFORE YOU SPEND MORE BUDGET Send me a message first. Honest read on the risks, the gaps, and what it would actually take to ship. No pitch. No commitment. NDA first.
