We've build a B2B SaaS from scratch and up to serving $M deals.

As a hands-on engineering manager I've both arranged and participated in both backend (Golang) and frontend (Vue.js) development of the system. Also I've managed servers (ubuntu linux), deploy processes, etc. 

And of course the main treasure is the great team whom me/we found and hired and cherished. Kudos to you guys and girls, you totally rock! :)
