I did my first conference talk with https://everest.engineering in Hyderabad. This is the presentation I used in the talk. The talk was about security at massive scale in microservices.
Feel free to use it in your presentations. No need to attribute but wonderful if you do.
Used some tools:
Parcel - bundling for minification and production use.
ImpressJS - for the cool transitions and presentation framework.
BulmaCSS - for some neat looking styles.
