Du H.

Full Stack Developer

I have 6 years of working experience in the software industry, and I am confident most as a Backend Developer and Data Engineer. For now, I want to spend more time on the freelance path, to help others solve their problem happily. As a backend developer: - I build microservices using Java and Go - I design a Database schema for features I work on. - I write REST API and work with the frontend team for integration. As a data engineer: - I do ETL tasks. - I write batch jobs and real-time jobs for streaming over 50 GB of data per day. - I store processing data into HBase, MySQL. - I visualize data to make it meaningful to others. Besides, I also spend time playing with frontend stuff such as NextJS, VueJS, CSS. Availability: My time zone is GMT+7, but I am flexible on working time, even at midnight. If you want to work with me for more than 30 hours, just say it, I will consider working more. Let’s work together to turn your idea into reality!
