나에게 맞는 산
A mountain recommendation mini-app inspired by the five elements of traditional Korean saju. Users enter a birth profile and explore a suggested mountain.
Built with React, TypeScript, and the Apps in Toss framework. The saju interpretation is entertainment content, not a scientific assessment or health recommendation.
The current app listing and direct link are being verified for publication.
A photo-booth mini-app project with four-shot layouts and a selection of frames.
Development projectA photo-based entertainment project using traditional face-reading interpretations.
Development projectProject descriptions reflect existing development work. Public release status and app links are pending verification. Interpretive content is for entertainment only.
Vibe coding is our primary development workflow.
Every PlayTwo service is developed with AI coding tools. We use natural-language instructions and iterative feedback to move from an idea to an implementation, rather than treating AI as an occasional add-on.
The founder guides the product, reviews the implementation, and decides what to release. As the portfolio grows, the development focus is on clearer requirements, repeatable testing, and maintainable code—not just generating more of it.
Future services · not yet launched
텐그램
A community app centered on sharing feelings and personal experiences. Video sharing is part of the direction being explored.
The video-sharing scope is still being defined, including whether it belongs within Tengram or a separate service. AWS is planned for Tengram’s infrastructure; the specific services and architecture have not yet been finalized.
Roadmap items describe intended work, not available services or current AWS deployments. Scope and launch timing may change.
An independent studio focused on consumer software.
PlayTwo is led by software engineer Taejeong Shim and based in South Korea. We work on compact mobile experiences, from the initial concept through implementation.
AI-assisted development is how we build across our services. Product direction, engineering decisions, and release approval remain founder-led.
