Backend-focused Full Stack Developer with 7+ years of production experience in PHP, Laravel, MySQL, Redis, Elasticsearch and ClickHouse.
I build business backend systems, admin platforms, payment workflows, queue-based services and data-heavy reporting features.
I have worked on high-concurrency business scenarios such as flash sales, lottery campaigns and online shopping mall features, as well as multi-dimensional analytics over hundreds of millions of log records per month.
I also have frontend experience with JavaScript, ES6, HTML, CSS and Vue, and have independently built a full-stack online shopping mall project.
My work focuses on backend APIs, database design, admin systems, payment flows, queue processing, high-concurrency business logic, frontend-backend integration and performance optimization.
I actively use modern AI coding tools such as Claude Code and OpenAI Codex to improve development efficiency, code review, refactoring, debugging and technical documentation.
I am currently expanding my backend stack with Go, improving my German language skills, and preparing for backend roles in Germany.
