Hello! My name is Christopher Walter and I am a senior software engineer with experience at Facebook, Google, and pre-series A startups Arize AI and Expo. My resume can be found here as a PDF: christopher_walter_resume_aug_2024_reverse_chrono.pdf. My LinkedIn profile can be found at linkedin.com/in/cwalter94, and my GitHub profile can be found at github.com/christopherwalter.

My foray into frontend development began during undergrad at UC Berkeley (2012 - 2016). I double-majored in Computer Science and Economics, but spent much of my free time working on miscellaneous web projects. My first "official" frontend role was an internship with a small company in San Francisco, CSRWare, where I spent sophomore year building web apps for companies to manage their corporate social responsibility efforts. During junior year I worked on a startup venture with a friend, building an e-commerce site for energy efficient lightbulbs — it failed, but I did learn just how low the bar is for angel investment. My final summer of undergrad was spent at Pivotal Labs, contributing to the open-source Concourse CI project.

In 2017 I joined Facebook (May 2017 - March 2020), which is where I really cut my teeth as a frontend engineer. I worked on both internal-facing and external-facing teams, contributing to Recruiting Products, Instagram Shopping, and Ads Manager. In 2019 I became one of three organizers for the annual UI Engineer Summit, where we brought all of Facebook's frontend engineers to Menlo Park for a day-long marathon of internal-only tech talks.

I left Facebook in 2020 to become a founding engineer at Arize AI (March 2020 - March 2021), where I was responsible for building a green-field web product as well as scaling an engineering team to work on it. We succeeded on both fronts, building a revenue-generating web platform and growing the frontend team to six engineers in the company's first year. During that time I learned invaluable lessons about growing good teams, cultivating company culture, and organizing the chaotic dance between engineering and product to deliver happy customers.

Despite our successes during Arize's first year, I ended up pursuing a new opportunity with Google (April 2021 - April 2022) as a senior engineer in Los Angeles. I spent the next year working as a Tech Lead for Youtube Ads, focused on deepening the company's understanding of the ads experience for users and leveraging that understanding within ads engineering teams to build new ads products.

Most recently, I spent a couple years as a senior engineer at Expo (May 2022 - August 2024), becoming the product owner for Expo Push Notifications and building out a new mobile analytics offering called EAS Insights. The Expo Push Notifications service is widely hailed in the developer community as the easiest way to set up Push Notifications for apps using React Native, and we were proud to build such a useful product that handled hundreds of millions of notifications sent to millions of devices across thousands of apps each day. The EAS Insights offering was Expo's foray into the analytics space, offering our users transparency and insight into their users behaviors and their app's growth.

As of August 2024, I am looking for new opportunities where I can build great products with talented teams. If you're interested in chatting about a particular opportunity, feel free to reach out on LinkedIn or via the email address on my resume.
