I am going line by line in work exp for vvdn

1. Demonstrated proficiency-> what were the apis for?
2. Optimized performance-> % of optimization and what was the volume?
3. Collaborated with clients -> what did you work on with client and any metric for satisfaction?
4. Proven track record -> vague, instead you can write something like you started using XYZ tool to increase your productivity and then evangelise it in your team to increase everyone's productivity by X hrs
5. Websocket apis -> you can write more about the work and dashboard and challenges around it
6. Led which projects?

Don't worry you need not be that specific at your exp level. But if someone wants to grill you, they can do so in the above manner.

Forgot to change the dates in front of projects, will change it.
