Danielle Menuhin
Data Operations Manager, eBay
Like most data operations professionals, my career started accidentally – Following a BA in Linguistics and Gender Studies and work in 2 startups I found myself at eBay’s taxonomy team, only to move later on to the catalog data operations group where I am today. After finding out I actually do have a career, I founded the Data Operations IL community this last summer, where we started having meetups and long over-due larger scale professional conversations. In between those roles and activities, I’m a fully fledged coffee snob, current 3rd place in the Israeli Aeropress Coffee Brewing Championship, and a home coffee roaster.

Danielle Menuhin
Data Operations Manager, eBay
Like most data operations professionals, my career started accidentally – Following a BA in Linguistics and Gender Studies and work in 2 startups I found myself at eBay’s taxonomy team, only to move later on to the catalog data operations group where I am today. After finding out I actually do have a career, I founded the Data Operations IL community this last summer, where we started having meetups and long over-due larger scale professional conversations. In between those roles and activities, I’m a fully fledged coffee snob, current 3rd place in the Israeli Aeropress Coffee Brewing Championship, and a home coffee roaster.

If data is king, then privacy is its crown jewel. Over the last two decades, I've worked as a technical leader in the data domain and have experienced first hand the importance of balancing the collection of valuable data with personal privacy protection. Inna examines real-life examples of privacy violations to emphasize the importance of privacy for data owners. Towards achieving privacy compliance, she taught: Different techniques to safeguard personal information, including anonymization, deliberate data decay, and differential privacy. How and where these techniques could be applied Additionally, the talk explored current privacy threats and the role of data engineers in ensuring privacy and security in handling personal and sensitive information. By the end of the talk, you will understand privacy challenges and learn practical solutions you can apply in your work. I believe that with data becoming increasingly central to our lives, privacy and data are equally important in the kingdom of data management.
We live in an era of big data and machine learning, where data drives the decision-making processes for organizations. This data must be managed and processed effectively to ensure the success of any system. A healthy data journey is a foundation for any big data and machine learning-based system to reach its full potential. The data journey encompasses all aspects of data management, from its collection and validation to its transformation into insights that inform decisions. The importance of a healthy data journey cannot be overstated. Without it, big data and machine learning systems results will be inaccurate, unreliable, and ultimately, less valuable. We delved into the critical components of a healthy data journey and the steps organizations can take to ensure the quality of their data. We explored the role of input validation, API design, data health monitoring, and well-designed data transformation mechanisms in ensuring the success of a big data and machine learning-based system. By the end of this talk, you will have a deeper understanding of the significance of a healthy data journey and the steps you can take to ensure that your big data and machine learning-based systems are functioning at their best. So, join us as we embark on this journey to discover the key to unlocking the full potential of big data and machine learning.
Trust is hard to gain and easy to lose, especially when it comes to data. Recall the last time you sent out a report: were your hands a little sweaty? Did your heart skip a beat? This is because data is never 100% accurate. As data people we strive for that sweet spot that’s between data-integrity-risk and that unattainable perfectly-correct-and-complete-data. We call that spot “good enough”. But can you be truly confident that your output is “good enough”? I assert that you definitely can! In this talk, I shared my data confidence meter - a framework for increasing assurance in your work and distilling the trust in the stakeholders you're working with.
What if I told you, you do not need all of your Big Data Architecture and Tech Stack. What if I told you, you could save a lot of money and resources all the while improving developer experience for all your data needs? DuckDB is revolutionizing the way we view and handle Big Data. I will show you how you can utilize DuckDB to your advantage and address your data needs using this in-process in-memory OLAP DB in ways you never thought possible. Having worked with Big Data and OLAP engines for many years now I know exactly where this new OLAP engine would have the highest impact in your architecture and how you should apply it.
