- Re-architected the app language localization services to support an exponential increase in QPS (over 120k QPS, with a burst rate of up to 700k+ QPS) and addressed latency spikes caused by GC pauses.

- Optimized the code to perform fewer and shorter garbage collections upon cache refreshes, leading to fewer and much shorter GC pauses and eliminating occasional spikes in API latency, with an overall improvement of 30%.

- Reduced the localization app boot time from 20 seconds to 4 seconds, enabling faster deployments.
