Work Experience

Lead Software Engineer, Backend

Carousell, Taipei City, Taiwan – (March 2022 - Present)

Senior Software Engineer, Backend

17Live, Taipei City, Taiwan – (March 2018 - March 2022)

• Managed a live streaming event for 3M active users utilizing the auth/user API, optimizing performance by separating the user cache from the general-purpose cache and relocating asynchronous tasks to a slow-consuming worker to reduce database overhead. Migrated the auth API to a microservice architecture for independent scaling, achieving test results demonstrating support for 3M active users in 10 minutes with only 10 Pods
• Initiated a microservice template project to accelerate the migration from a monolithic to microservice architecture for other teams. Within the first month, 5 internal projects adopted the template to develop their own microservices
• Reduced Redis cache costs by isolating the user cache from the general-purpose cache, requiring only 10% of the memory size of the general-purpose cache to effectively serve all platform user information requests
• Collaborated with the backend engineers from other teams to enable the purchase of product packages in a single order via In-App Purchase. Designed and developed a next-generation billing system to support multiple product types within a single order
• Built a new-generation billing system to track user purchase order status easily, the new-generation billing system creates 65% amount of orders and the new-generation billing system serves 85% of selling channels
• Reduced report generation times by 60% by consolidating multiple queries into a single query to minimize network latency, optimizing database query index to decrease query time, and leveraging workers to accelerate report calculations

Software Engineer

SquareX Inc., Taipei City, Taiwan – (May 2016 - Feb 2018)

• Designed and developed an IoT ACLs mechanism and IoT MQTT protocol to enable seamless integration and remote access for various types of IoT devices
• Developed core APIs for user, friends, and IoT services using AWS serverless architecture
• Reduced Lambda execution time by minimizing code size, optimizing code to reduce cold start time, and implementing a pre-warm module to ensure Lambda readiness for faster request handling
