I'm a Unity game developer based in Bali, building 2D, 3D, and mobile games from concept to finished product. I code in C# and have shipped games across a wide range of genres such as platformers, puzzle games, turn-based mechanics, narrative experiences, and 3D physics-based games with around 10 projects available on itch io. A lot of my experience comes from game jams where I've not only competed but won, which means I know how to scope a project, make the right cuts, and deliver something that's actually fun to play under real constraints. I also founded Unbounded Souls, an indie game studio where I lead the full development pipeline, from game design and programming to coordinating a team across art, music, and production. On top of that, I completed a dedicated Game Developer Cohort at Infinite Learning Indonesia and I'm currently at Apple Developer Academy @ BINUS Bali, deepening my skills through challenge-based learning and expanding how I think about building interactive experiences. I'm reliable, communicative, and serious about the craft. Whether you need a game prototype, a specific mechanic built out, or a polished mobile experience I'll bring it to life. Let's build something fun.

I help clients turn game ideas into scalable Unity products, from prototype to live production, including backend, multiplayer, and deployment. I’m a Unity developer with 10+ years of experience working on mobile, web, and PC games. I don’t just build the client side, I also design backend systems, multiplayer architecture, and game economies. I also build AI-powered tools and workflows using agents (e.g., Codex with MCP), enabling automation, tool integration, and smarter development pipelines. I’ve worked on multiple shipped projects across mobile, WebGL, and PC, including multiplayer and backend-heavy systems. Core Expertise: • Unity (Android, iOS, WebGL, PC) • Multiplayer (Photon, SmartFoxServer) • Backend (Java / ASP.NET Core + MongoDB) • Blockchain integration (EVM, zkEVM) What I can deliver: • Full game development (client + backend) • Scalable backend and game logic • Real-time multiplayer systems • Deployment and CI/CD pipelines • Dashboard for custom management ❝Tim delivers beyond expectations and brings clarity to complex projects.❞ If you have a game idea or need help scaling your project, feel free to reach out. I’m happy to discuss the best approach for your case. Best regards, Timothy Hermawan

I'm a Unity Developer who believes that building a successful game is about more than just writing code. There are many skilled Unity developers out there, so what truly differentiates me isn't just my technical ability. It's the way I work with my clients. I don't see myself as someone who simply completes assigned tasks or fixes isolated problems. Instead, I aim to become a reliable teammate who genuinely cares about the success of your project. My approach is proactive. I don't just build what is requested. I also think about what could make the game better. If I see a better solution, a cleaner implementation, an optimization opportunity, or a way to improve the player experience, I'll bring it to the table. I believe great games are built through collaboration, communication, responsibility, and shared ownership. When we work together, my goal is to support your vision and help turn your ideas into the best possible product, not just deliver features. My main areas of expertise include: * Mobile Games * WebGL Games * Action Games * Gameplay Programming * Game Feel and Juice * Performance Optimization * Gameplay Polish * UI/UX Polish, Animation, and Responsive Interfaces One area I particularly enjoy is UI/UX polish. I love refining interfaces until they feel clean, responsive, visually appealing, and satisfying to interact with. I believe great UI should do more than look beautiful. It should reinforce your game's identity, enhance the gameplay experience, and naturally support your overall game design. If you're looking for someone who is invested in your project's long-term success, communicates openly, takes ownership, and enjoys solving problems together, I'd be happy to be part of your team.

I build and fix Unity multiplayer: server-authoritative netcode, matchmaking, state sync, and the bugs that only show up at 200 ms ping. 10 years in Unity/C#, shipped on four networking stacks: FishNet, Photon (Quantum), WebRTC, and MLAPI/Unity NGO. WHAT I DO: - Multiplayer architecture: server-authoritative design, client-side prediction, lag compensation, state reconciliation - Netcode implementation and debugging in FishNet, Photon, Unity Netcode for GameObjects (NGO), WebRTC, or your custom stack - Matchmaking, lobbies, and session flow (Steam and mobile) - Performance passes on networked gameplay: bandwidth, tick rate, interpolation tuning - Code review / second opinion on an existing multiplayer codebase RECENT PROOF: - Led netcode on a co-op looter-shooter on Steam (Photon, deterministic rollback) as the networking specialist on a 7-programmer team - Built 3v3 real-time mobile multiplayer end to end on MLAPI (the framework Unity evolved into Netcode for GameObjects), including the server work that kept concurrent-match costs low - A decade of shipped Unity titles across PC, mobile, and web HOW I WORK: scope first. I ask the questions that size the job before quoting it, I flag risks early, and I deliver with clear written handoffs (architecture notes, repro steps, annotated code). My first Upwork client's review: 5.0 stars, endorsed for Detail Oriented, Solution Oriented, Clear Communicator, Committed to Quality. If you have a multiplayer feature that will not sync, a netcode decision you want a second opinion on, or a game that needs online play added, send me the details and I will tell you honestly whether and how I can help.
