Position: Senior / Technical Lead JavaScript developer
Category: JavaScript
English level: upper
Years of experience: 10

Every experience not about managing team but about developing system (architectural decisions) and helping team to reach final goal (my official position always just engineer):

Team from 8-10 developers which successfully migrated big legacy system (cash cow) to new technology stack.

Team from 10 developers which have built from scratch platform in the travel area.

Team from 4 developers which have built from scratch logistic platform.

Improved stability of the big platform for delivering new features. Performance optimization which decreased requests cost in 2-3 times.

And much more...
I've started my journey as a modern title says as "Full Stack Web developer". My first Web layouts were with <tables> for IE6, BE part was written on PHP and design was drawn by me in the Photoshop.

Now I have more than 10 years of real production experience with different big projects and various technologies (heh - joomla, wordpress, jQuery, symphony, react, angularJS, etc :D). All this time I was working with WEB and mostly on the FE side. Usually I did changes on the BE side when our teams needed such help but not an expert there.

Last 2+ years working with project based on microservice architecture and stack on my side based on ANGULAR / Apollo GraphQL (I've used UPPERCASE for people who needs last years ONLY with REACT and will ask on interview how to write react hooks).
About developing process:
Project with really interesting and difficult technical architecture. Possibility to be concentrated on the FE side but to have a chance invest my knowledge and skills in different areas - BE / CI/CD / etc.

About technical approach:
If you think that engineer who has 10+ years of real production experience at this moment MUST work with your specific tech stack and he can't learn e.g. React / VUE / KOA while joining team - we are not on the same way.

About project area:
Please do not propose projects from Gambling area. I know that from technical point of view such options might be quite interesting, I've already had such experience, but do not want to repeat it because want to develop something more useful.
