# Hakan Alpay > Fullstack Web @ DoorDash | Prev: www/ios @ Meta | Node.js Contributor Location: New York, New York, United States Profile: https://flows.cv/hakanalpay I'm an iOS and Web engineer at Meta: I've worked on features that have affected billions of users such as the new Facebook iOS share sheet, the storage management for E2EE chats, and group fundraisers for Facebook groups, on both web and mobile. I've run tests on many variants of my features that involved millions of users and did the data analysis to determine learnings for the team and inform our launch criteria. I've done many front end projects on my own as well: Bmaps is a web app of all the events at UCLA on a map and calendar, and I built it with Angular as the frontend and Flask as the backend; serving both with Docker Compose on an AWS EC2 instance. This app quickly became popular in the school, particularly among freshmen who wanted to become more involved in campus activities. I have a thorough mix of industry experience and private project experience in full stack and mobile development. If you think I would be a good fit for your role, please do no hesitate to reach out :) ## Work Experience ### Full Stack Engineer @ DoorDash Jan 2024 – Present | New York, New York, United States ### iOS Engineer @ Meta Jan 2022 – Jan 2023 | Menlo Park, California, United States • Created the new Facebook iOS share sheet used 500+ million times per day by 2+ billion people to share content from Facebook to their story, timeline, Messenger chat, or other off-platform destinations. • Developed the share sheet with Objective-C++, Component Kit, Graph QL (for contact fetching), Xcode, etc • Created numerous experiments that tested different variants on 2+ million people per test. • Did the data analysis of the experiments by measuring the impact on top line metrics for key variants and investigating the cause of any regressions.
