Hi, I’m Shaodong, a Unity developer with 6+ years of experience building gameplay systems, combat frameworks, multiplayer features, mobile games, PC games, VR applications, and interactive 3D projects. I can help you develop, optimize, debug, or improve Unity projects—from early prototypes to production-ready gameplay systems. My main areas of expertise include: • Unity and C# gameplay development • Combat frameworks and character systems • Skills, Buffs, attributes, state machines, and damage systems • Monster AI and player abilities • Multiplayer combat and server-authoritative architectures • UI systems, animation, VFX, object pooling, and resource management • Mobile and PC performance optimization • Unity Editor tools and development workflow improvements • VR and interactive multimedia applications In a 3D online fighting game, I led the development of the core combat framework from scratch, including skills, Buffs, character states, combat flow, VFX, and client-side combat presentation. I also created a debugging tool that reduced battle testing and issue reproduction time by approximately 80%. For a mobile top-down shooter, I implemented around 40 monster AI types and more than 80 player skills. I optimized combat scenes with over 200 enemies, improving performance from approximately 10–15 FPS to 50–55 FPS on Android devices while reducing memory usage by around 400 MB. I am comfortable working with existing codebases, identifying technical problems, improving architecture, fixing bugs, and delivering new gameplay features. I also write clear technical documentation and communicate progress regularly throughout development. Whether you need a gameplay prototype, a combat system, multiplayer features, performance optimization, bug fixing, or Unity development support, I will focus on providing a reliable and maintainable solution.

Solo full-stack developer and founder of Tru-Resolve LLC, building production Flutter mobile apps with Supabase backends (auth, realtime, storage) and custom business websites end to end: planning, design, development, and launch. Background includes 20+ years of hands-on experience in enterprise software, cloud architecture, and systems administration prior to founding Tru-Resolve LLC in 2020. Every project is scoped, built, and delivered by the same person, with no handoff between whoever sells the work and whoever writes the code. Recent work: - TruBrief: a news aggregation app with AI-generated summaries, automated fact-checking, political bias ratings, live weather alerts, and market data, with zero ads. Full Flutter and Supabase stack including a production content pipeline and an OTA update system. Live and in active use. - Tru Shark: a shark species encyclopedia and research app covering 35 species with licensed photography, species comparison, and a freemium subscription model via RevenueCat.

I work fast, communicate clearly, and treat every project like it has to hold up in production.

I'm a senior full stack mobile engineer with 7+ years building production apps from 0 to 1 across React Native, TypeScript, Swift, and Node.js. I've been a founding engineer across multiple startups — owning the entire stack solo, making architectural decisions without a perfect spec, and shipping things real users depend on. What I build: React Native and iOS apps from concept through App Store launch Node.js backends with REST APIs, authentication, real-time systems, and database architecture Full stack Next.js web platforms AI-powered products using OpenAI and Claude in production Recent work: Blast — sole engineer for 4 years on a consumer video social platform. React Native, Node.js, MongoDB, AWS. 99.9% uptime, 8x weekly engagement. Breefly — AI news app live on the App Store. Swift, TypeScript, OpenAI integration, custom categorization system. Ciao Guides — Native iOS travel itinerary app. Swift, SwiftUI, MapKit, LookAround. Valtd — Blockchain social platform on Lens Protocol. React Native, Next.js, wallet auth, token swapping. How I work: I build with AI daily using Claude Code — it's core to how I move fast without sacrificing quality. I treat every project as if I'm the founding engineer — full ownership, clear communication, and shipping things that actually work. If you need someone who can own a codebase end to end and deliver without hand-holding, let's talk.

I am an experienced software developer proficient in designing, developing, and publishing user-facing experiences. I have worked on both mobile and web projects, gaining skills in the vast landscape of development frameworks currently available. No matter what your idea is, I can choose the right tech stack and turn your vision into a reality.

I build custom software fast — web apps, mobile apps (iOS & Android), dashboards, backends, AI automations, and the integrations that tie your tools together. Not prototypes or mockups. Real, production-grade systems you own completely. What I can help you with: • Custom web & mobile apps, built and shipped end-to-end • Internal tools & dashboards for teams that have outgrown spreadsheets • AI automations (drafting, data processing, workflows, chatbots) • MVPs for founders who need to launch, not just plan • Rescuing stalled or half-finished projects and getting them production-ready • API integrations connecting the systems you already use I pair 10+ years of engineering experience with modern AI tooling, so work that used to take a big team months gets done in weeks — without the "AI-generated mess" you'd have to rewrite later. I care about clean, maintainable code and actually shipping. I recently built and launched Locker Lounge, a full production mobile app (iOS + Android) — backend, app-store submission, real users — solo. That's how I work: real products, delivered. If you've got something you need built (or fixed) and you value speed and quality, let's talk. Tell me what you're trying to accomplish and I'll tell you honestly whether I'm the right fit.
