I was a mobile engineer and then became a backend engineer with 5 years of experience. My most experienced languages are Java and Golang, although I've written fair amounts of code in Python, Ruby, and Javascript over the years. Some interesting topics I am working on are database design, system observability, and designing the distributed system.
I have worked on young start-ups, unicorn, and enterprise companies with experience through many roles, e.g. an engineer, a team leader, and a short time of being a project manager. Because of that, I can share viewpoints to achieve a common goal with many stakeholders, e.g. end-users, DevOps, and software engineers.
