What I'm looking for

I am looking for a role that fosters innovation and collaboration, where I can leverage my backend engineering skills to drive impactful projects and contribute to a dynamic team.

I am a Backend Engineer with over 6 years of experience in designing and developing scalable, distributed backend systems across various industries, including AI content platforms, smart manufacturing, and energy tech. My proficiency in Golang, Java, and Python, combined with a deep understanding of microservices architecture and event-driven systems, allows me to enhance system reliability and deliver impactful backend infrastructure for global platforms.

Currently, I work at TikTok, where I build core backend services for AI content generation, implementing notification logic to drive creator re-engagement. Previously, at Tesla, I maintained and enhanced backend infrastructure for Manufacturing Execution Systems, developing modules for order-specific manufacturing. My experience also includes engineering backend systems for smart building data at Envision Digital and developing enterprise-grade ERP systems at Works Applications Co., Ltd.
