• ·Developed a Texas Hold'em poker game entirely from the ground up,implementing all necessary functionalities such as shuffling, dealing cards, and player bet/raise,card comparison, win/loss determination and so on.The game supported multiplayer gameplay and real-time gaming experience using websocket.There are 20,000 users every day in our poker game plantform,and the game supported 10,000 players in one mtt poker game with only 8cores and 4GB memory configuration.
• ·Passionate about learning new technologies. During off-hours, I self-learned Rust and rewrote the high-CPU-usage code logic of the poker project in Rust. Compared to Golang, the rewrite achieved a 5x increase in computation speed and a 100x reduction in memory usage.
• ·As a beginner in Rust, I identified a bug in the Comprehensive Rust learning material (Google's internal teaching resource), submitted a pull request, and successfully had it merged into the main branch.
• ·Take over and optimize the development of a VPN accelerator project, which include acquiring/updating accelerator nodes through various methods, supporting partitioning of users based on their location and category, displaying user login/logout information and logged phone name, and enabling the purchase of VIP features through multiple payment methods. Optimize all app functions and components of the project and ensure project quality.

• ·Design and code the Tencent Posting Advertisement System. Instead of manual advertising placement and optimization work, our project automatically monitors the advertisement metrics (e.g., daily budget) based on the customer's monitoring rules. When the advertisement metrics meet the conditions set by the customer, the corresponding operations (e.g., resetting advertising budgets) are executed. This system greatly reduces the manual workload and increases the number of advertisements that can be managed by a single person.
• ·Design and code the Tencent Advertisement Diagnosis System. By disclosing detailed data at each stage of the ad's full lifecycle (recall, coarse ranking, fine ranking), such as pass-through rate, pass-through count, models used in coarse and fine ranking, and the consistency between them, as well as various ad metrics (e.g., eCPM, pCTR, pCVR, pCTR bias, ROI, target CPA, risk control factors, pricing factors, and eCPM values compared with ads under the same industry and account), the system facilitate internal clients in ad diagnostics and troubleshooting.
• ·Design and code the new features of the Tencent Advertisement Diagnosis System, including automatic over-cost diagnostics and off-target exposure diagnostics.

• ·Managed three project teams: virtual currency, settlement, and middleware.
• ·Designed and developed backend services from scratch. Clearly decoupled multiple modules such as settlement, payment, and risk control in the currency circulation process from a business perspective.
• ·Technically adopted a microservices architecture, led the design of the strace-log system, customized the Spring Boot framework, developed a unique incremental sequence number System, and an RPC call framework.
• ·Led the architecture and development of the company's delayed message middleware (providing delayed message cancellation functionality), wrote core code, and spearheaded the development of a unique incremental ID middleware and a log-based collection, analysis, and alert system.
• ·Led the initiative for project interface configuration, allowing interaction with new systems using the same set of machines and code with different configurations, significantly reducing the number of machines and development time.
