đź“– Summary

Vice President Of Technology @ Blueprint, Technology for Non-Profits I dockerized the Ruby on rails development environment in Blueprint. In addition, I developed tutorials and labs on Git, Ruby on Rails and ReactJS for new member onboarding. I also reduced expenses by combining internal services on Heroku into a single AWS server. From June 2017 to December 2017 (7 months) San Francisco Bay AreaCo-founder @ ArkC Technology Inc. With many great people, I worked on building a state-of-the-art proxy (VPN) solution. Through this process, I understood the limit of what engineering is capable of. From July 2015 to May 2016 (11 months) Beijing City, ChinaSoftware Engineer @ Stripe San Francisco Bay AreaSoftware Engineer Intern @ Stripe >> Designed and developed internal programming abstractions for Spark SQL, which reduces hours of work for each application and helps Stripe meet urgent data locality regulations by enabling transparent redistribution of data across geolocations>> Developed a Scala library to transform complex Spark schemas to Protobuf message definitions with cats typeclasses>> Collaborated with team members on containerizing ETL job environments with Kubernetes From May 2019 to August 2019 (4 months) San Francisco Bay AreaUndergraduate Researcher @ University of California, Berkeley Designing and implementing replication for Global Data Plane ( with Nitesh Mor and Eric Allman.Anti-entropy algorithm on DAGs without ordering imposed by writer: From October 2018 to July 2019 (10 months) Project Leader @ Free Software Foundation >> Led a team of six developers to create a mobile app to support campaigns and donations for open source software>> Designed and implemented a microservices architecture with an API gateway to allow secured centralized login and serve consistent information about users and transactionsVia Blueprint, Technology for NonprofitsGithub fork: From September 2018 to May 2019 (9 months) Part-time Software Engineer @ OnSpecta, Inc. OnSpecta specializes in accelerating inference of neural networks.I have created a customized execution engine for Tensorflow that works with OnSpecta's deep learning service. I started by identifying a proper internal interface in Tensorflow’s source code to support third-party execution engine; the interface has remained stable and supported porting customization of Tensorflow across major versions. Our customized version of Tensorflow allows users to deploy neural networks with full power and support of Tensorflow along with acceleration provided by our proprietary math kernels and other techniques.I also worked on improving convolution kernels that outperformed OpenBLAS and Intel MKL. From November 2017 to October 2018 (1 year) San Francisco Bay AreaSoftware Engineer Intern @ Dremio I improved query performance by leveraging interesting order. Specifically, I have implemented a distributed asynchronous merge join, and introduced another way to load, distribute and process data across nodes for processing based on hash buckets.I have worked on our query pushdown engine for Elasticsearch to support its latest REST APIs, and it is included as a major feature in our latest release.I have also engaged in responding to urgent customer issues and participated in the full process of diagnosis, fixing and validation of a top priority customer bugs.Dremio is the Data-as-a-Service Platform company. Created by veterans of open source and big data technologies, and the creators of Apache Arrow, Dremio is a fundamentally new approach to data analytics that helps companies get more value from their data, faster. Dremio makes data engineering teams more productive, and data consumers more self-sufficient. Founded in 2015, Dremio is headquartered in Mountain View, CA. Investors include Lightspeed Venture Partners, Redpoint, and Norwest Venture Partners. For more information, visit From June 2018 to August 2018 (3 months) San Francisco Bay AreaFullstack Developer @ Rocky Mountain Institute Working with my team at Blueprint, Technology for Nonprofits, I created a collaborative questionnaire where users can invite other users to answer specific questions. The questionnaire is used by Rocky Mountain Institute to collect environmental data of commercial buildings.We used Ruby on Rails for backend, React & Redux for frontend.I implemented the end-to-end feature of users inviting others to answer specific questions, and added access control to the application. I also integrated the questionnaire with AWS S3 for attachment upload.In addition to features, I identified and optimized for N+1 queries in Ruby on Rails serializers to reduce page loading time. From February 2018 to May 2018 (4 months) Software Developer Intern @ Nimble Storage At Nimble Storage (now HP Enterprise), I had a deep dive into modern OS techniques.I spontaneously proposed to improve asynchronous task framework (ATM) with coroutines, so that complex file system logic may be rewritten in a way intuitive for developers. It is like implementing await/async pattern in C++.I worked on building high performance (~100Gbps) data channels between controllers (servers), with minimum impact on other applications. In the process, I used different kinds of technology: e.g. TCP/IP, PCI-E address mappings, RDMA, interacted with customized hardware drivers, and worked across teams.I also researched about faster hashing algorithm implementation, and re-implemented our Fletcher32 checksum algorithm using AVX2/AVX512 to 4x throughput. Peak performance on a specific system improved by 20% because of my work. From May 2017 to August 2017 (4 months) San Francisco Bay AreaBackend Engineer @ Berkeley Institute of Data Science Designed a non-preemptive scale algorithm for Kubernetes cluster of a UC Berkeley course, reducing costs by 70%Developed backend for nbpuller, an online tool that abstracts over Git, to offer version control of students' code From January 2017 to May 2017 (5 months) San Francisco Bay Area
