# Cheng Zhang > Software Development Engineer Location: New York, New York, United States Profile: https://flows.cv/chengzhang ## Work Experience ### Software Engineer @ DoorDash Jan 2023 – Present | New York, United States Ads & Promotion ### Software Development Engineer @ Amazon Jan 2020 – Jan 2022 | Greater Seattle Area Abuse Prevention ### Software Engineer Intern @ Spell Jan 2019 – Jan 2019 | Greater New York City Area • Took part in the development of an AI platform designed for ML/deep learning engineers. • Implemented model server deployment service on web console & resource uploading service for user-created clusters. • Worked on all front-end (JavaScript, React, Redux), back-end (Go, PostgreSQL) and CLI (Python) development. ### Research Intern @ Face++ Jan 2017 – Jan 2018 | Beijing City, China • Developed a scene classification app with 3 employees from scratch, which supports 18 categories and 200 scenes. • Using python to collect and clean data from public datasets, as well as maintaining entry data for 1,000,000+ images from various sources and scattered in different paths. • Designed neural networks specifically for scene classification tasks with Python. Implemented teacher-student structure in the network for cross-domain scenes and get 3~5% performance boost. • Technology sold to Lenovo and Smartisan for the smart phone products. ### Research Intern @ Beihang University Jan 2016 – Jan 2017 | Beijing City, China • Employed Convolutional Neural Network with Caffe to recognize and classify the 3D shapes based on the rendered images of them on large databases. • Devised a view discerning unit to adjust the weights of different views, which improved the 3D shape retrieval performance of the unweighted network by about 4% on Mean Average Precision (MAP). • Extracted spacial structural information from a set of image features through recurrent neural networks and got a performance boost of about 5% on MAP, compared to naive feature merging techniques. ## Education ### Master's degree in Computational Data Science Carnegie Mellon University Jan 2018 – Jan 2019 ### Bachelor of Engineering - BE in Computer Science Beihang University Jan 2014 – Jan 2018 ## Contact & Social - LinkedIn: https://linkedin.com/in/cheng-zhang-a40824170 --- Source: https://flows.cv/chengzhang JSON Resume: https://flows.cv/chengzhang/resume.json Last updated: 2026-03-23
