and other things...

projects
overview: an anonymous mini-social-network-twitter-like experience. every f5 or simple-tap on the post-it, the message swaps to a random one. double-clicking it enables you to send your own message. built with clean code standards and a clear separation of concerns to ensure a highly scalable and decoupled backend. technologies: * backend: java, with postgresql database * frontend: nextjs, react
overview: a web-based playground-terminal simulator. designed to handle commands as independent execution units following SOLID principles. users can safely authenticate, call a message from Benius API, and chat with an AI asynchronously. technologies: * backend: java with postgresql database * frontend: nextjs, react * external apis: groq API low-level implementation
overview: a point-of-sale and digital menu system built for a local food shop. customers place orders with dynamic delivery fees computed on the fly. admins manage the incoming event-driven orders queue, view history, and print receipts. optimized for low latency and high availability. technologies: * backend: event-driven node.js architecture via nextjs serverless functions, integrated with postgresql database * frontend: nextjs, react
