Nelly Sattari

Nelly Sattari

What fascinates us, engages us and what engages us, helps us to learn.

Stories told with enthusiasm build connections. They build trust and help us interact with greater engagement and creativity for stronger technical solutions.

Nelly Sattari loves problem-solving and is passionate about driving minds to engage with technology. She is a software engineer and Tech Engineering Manager based in Sydney, Australia and has spent her entire career involved in the IT industry.

Her focus is building teams who create modern applications, and she is indebted to her full-stack development background and the knowledge she gained there.
Also, she leveraged the synergistic effect of her technical skills and leadership abilities to lead the inclusive, local IT communities that are her favourite playground and where she facilitates knowledge-sharing platforms, supports user groups and nurtures beginner expertise, while steering clear of buzzwords for a more practical and tangible approach.
That combination led her to be awarded as Microsoft Azure MVP (Most Valuable Professional) four consecutive times.

Come and join Nelly in an armchair-like, story-focused conversation to unpack familiar, yet often undiscussed, problems that will unveil new and thought-provoking solutions.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2024

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2024.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2024. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 38,000 unique accepted speakers this year, the 3% is 1036. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2024. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
