> Software Engineer at Google

Location: San Francisco Bay Area, United States
Profile: https://flows.cv/yuchenshi

I'm currently working at Firebase, Google's mobile and web development platform (part of Google Cloud offerings). I'm the Tech Lead of Firebase Emulator Suite and contributor to Realtime Database, App Check & Rules. Local development and testing has been my late focus here and I lead my team to help 30,000+ monthly active developers to supercharge iterating on their mobile and web app.

Previously, I worked at Clarity Movement Co. I led the software development of air quality monitoring systems, providing information to create a better world.

My three years at Google has brought me solid experience in server development with Java, REST APIs, gRPCs and so on. I've designed and implemented distributed systems, databases, data processing both at Google and Clarity and I'm ready to take challenges to build scalable systems or improve them any time. I also have a deep background in web application development, which allows me to deliver solutions end-to-end such as the Firebase Emulator Suite, web management platforms at Clarity and Qianye.

On the bottom of my technical stack, I have a solid knowledge foundation of computer science and systems. I'm familiar with algorithms and data structures and can implement them using JavaScript, Python, C++, Java, C# and more languages. Data processing and visualization are also part of my skill set. I use Linux daily as the primary operating system and I have worked with many services and wrote scripts on Amazon Web Services.

Besides technical advantages, I have good communication skills and I work great in a team. I led the whole Firebase Emulator Suite team at Google, balancing the project between requirements and delivery. It's just like how I did it before at Clarity, but on a much larger scale. Moreover, I learn new stuff from time to time and can quickly adapt to changes. Even if something is not (yet) on my profile, I'm open to any opportunities that allows me to add that to my skill set, especially learning by doing.
