At Loma Technology Co. Ltd., I develop backend services and APIs with Laravel, PHP, and Go. I contributed to a comprehensive HRMS and implemented an AI-powered workflow form design using OpenRouter and GPT-OSS-20b.
I developed backend components for the Kla Klouk real-time gaming platform, including concurrent game-round processing, betting, settlement, and WebSocket result distribution. I also implemented a reporting assistant that turns natural-language questions into SQL, with safeguards and custom MCP tools.
Previously, at I-Serve Online Mall, I developed Laravel applications and backend services for e-commerce, messaging, and e-wallet workflows. My work also includes recruitment platforms, case management, and contributions to CakePHP and Filament documentation.
