More than 10 years overall programming experience, around 8 years in JavaScript tech stack. My key experience is more back-end oriented, system design, distributed systems design, database design. I am also good at working with the front-end side of the project using mostly Angular and React. My kind of mantra is to do as much as possible on the back-end and keep the front-end as simple as possible, so there will be less resource intensive tasks running on the tiny users client like a slow laptop or oldish mobile phone.
