I am a Designer with the hands of an Artist and the logic of a Developer. With a background spanning over 50 solo-developed Flash games and 10,000+ stock assets, I have grown into a Technical Game Designer who designs ideas with production and implementation in mind. My Superpower: I don't just design interfaces; I build functional systems. Using Generative AI (Midjourney/ Nano Banana) for assets and LLM-assisted coding (Claude/Gemini Vibecoding) for logic, I can prototype complex ideas in Unity or HTML5 in days, not weeks. What I bring to the table: • Extreme Productivity: In the last 3 years alone, I delivered 80+ complete graphic sets (UI, Characters, Environments) for HTML5 casual games. I am comfortable with both long-term routine production and "Day 1" creative brainstorming. • Hybrid Skillset (Art + Tech): I design beautiful, player-friendly UI/UX and immediately implement it into the engine. I understand game architecture, flow, and mechanics, ensuring my designs are always "developer-ready." • AI Innovation: I actively use AI to remove bottlenecks. From generating consistent game assets to writing C# scripts for Unity, I treat AI as a force multiplier for the team. Recent Solo Projects (2025): • Released 3 HTML5 Games: Full cycle development (Art + Code), 2 published on Google Play. • Developed 3 AI-Powered Apps: Built "ParentScope", "Copy-Bara", and "Corgi Philip" using 100% AI-generated code. Tech Stack: • Design: Photoshop, Illustrator, Figma, Corel Draw. • Engine: Unity, HTML5. • AI: Midjourney, Nano Banana, Gemini, Claude (Vibecoding flow). Open for B2B contracts worldwide.
