I have 6+ years’ experience for product development. As a backend engineer, I use Go as main programming language and interest in modern software engineering practices, like microservice, clean architecture, DDD. I also like to co-work with PM, SDET, SRE, frontend engineer and other stakeholders at an agile culture. I can build up a backend system by (1) evaluating techniques for long-term product roadmap; (2) designing mircoservice architecture; (3) improving DevOps maturity level and developing efficiency.
