40 unsung heroes of Dublin’s Tech Scene

23 September 2016

Dublin has an underground movement of amazing people that get very little recognition for their contribution, and yet are vital to the success of the Dublin tech scene. Everyday people who are donating their time to help improve knowledge sharing and networking opportunities that are vital for the success and growth of a tech scene.

While we could have collated a list about ten times as long we’ve had to limit our list to 40 key people for brevity’s sake. Let us know in the comments who we are missing and we will continue to update this list as a thank you to the unsung heroes. Aside from some loose groupings of Development, Design, Entrepreneurship and Support the people are listed below in no particular order.

Eoin Brazil Ger Hartnett Joe Drumgoole

The MongoDB meetup reflects the growth and popularity of the database itself. Early sessions were introductions to dynamic schemas and document oriented databases but recent talks are more about the challenges in scaling Mongo and multi tenant deployments. Eoin, Ger and Joe obviously believe in the database but they may be a little biased since they all work at MongoDB. However there is no denying that the database has a lot of traction, particularly in the startup world. One way to show how highly regarded it is as a database is that it is the default database for all of the latest development stacks - MEAN, MERN, MEEN among others.

The ReactJS meetup, just like its namesake library is a fairly new entrant onto the scene but it is gaining a lot of popularity. React was a pioneer in the virtual DOM space which offered a much higher performance option for web applications with many data bound objects. The complementary Flux architecture pattern espoused the benefits of a unidirectional flow of data based on the belief that “shared mutable state is the root of all evil”. Both Rob and Cian work as software engineers at Hubspot where they are putting React through its paces in production code.
