So I'd say the time I took the risk was, I actually went against the recommendation of my manager. Not directly, but essentially I was put on a project at Niagara and I was looking at a lot of the contract amendments and I analyzed our contract negotiation with Uber. And so as I was looking at the whole data, trying to see the discrepancies and really seeing, okay, what lanes should we negotiate, seeing what are the terms of negotiation that we should use, and then finally, I wanted to also forecast on terms of a long-term growth. So not just necessarily for just this term, but see how that would last for the future quarters as well. So kind of taking those into consideration while I put them all out into a matrix and showed the team, the director, and a lot of my team was thinking that we should go with the option that saves us the most amount of money. I'll put the $700,000 to $800,000 for the quarter, implementing this new amendment that I actually disagreed. And I suggested we just take somewhere closer to about the $600,000 range because for two reasons, one, I noticed that the lanes that we included in the $600,000 would lead to better client relations with Uber as a long-term and one of our biggest carriers. And two, I also noticed that in the long run, we actually would save a little more just because in the future quarters with seasonality to keep into account, those lanes were not always going to save us the most amount of money. So maybe while the $700,000 to $800,000 option would save us that much in the first quarter, when it comes down to the winter, it would save us only about $300,000 versus the $600,000 option is a little more consistent throughout the seasons. And so we actually noticed that in terms of a long-term growth for the year, we would save a lot more. So that was a time where I kind of took a risk to go against and maybe recommend something slightly different than my manager. But I think the director, when he heard me say these things, he took those into consideration and saw my analysis and saw that I was able to back up kind of my decisions and this type of risk to making sure I'm minimizing it as much as possible. So I think that was something that he really appreciated and that the VP of supply chain ended up deciding to work towards.

我会主动和组内的成员进行沟通，遇到风险或者问题及时上报，同时我也会考虑是否有我可以帮的上组内工作的方面

在我刚加入我们团队对产品移动端重构的过程中，我发现大家在移动端设备的调试上不够熟悉，团队选择使用的是chrome的模拟工具，但是在不同设备的兼容问题的解决上效率很低。发现了这个问题之后，我向组内的资深工程师咨询，掌握了我们的项目的构建和调试方案，通过提供fiddler，charles脚本和文档的形式，分享给整个组一套切实有效的移动端调试方案，提升了组内的mobile debug效率。之后，团队变得更信任我，在我做为新人的情况下，主动让我负责了更复杂的项目。

l, I initially built automation scripts for trade reconciliations and reporting using standalone Python and UNIX-based cron jobs. These worked well for smaller data volumes, but as our operations scaled across global teams in London, Hong Kong, and the Bahamas, performance and maintainability became a bottleneck.

I realized I needed to adapt my workflow to better support large-scale, distributed processes. So, I changed how I worked by migrating critical pipelines from PostgreSQL and flat scripts into a more robust ETL framework using Databricks and Delta Lake. I restructured batch processes into streaming jobs and modularized the Python code to be production-grade. I also started using Kafka and Kubernetes to improve system reliability and orchestration.
