Dan Mallott is the Head of Platform and Infrastructure at e-conomic in Copenhagen, Denmark. His passion is for distributed architecture, designing and building high performing service layers from the API down to the database.
As Head of Platform and Infrastructure, Dan is responsible for leading the Platform, SRE, and API teams in building a solid foundation for the e-conomic product. Previously, Dan was focused on leading the Platform Team in improving the cross-cutting concerns in the e-conomic application, including improving security, improving messaging performance, and managing the migration to .NET 6.0.
Before joining e-conomic, Dan was a Senior Principal for West Monroe, based in Chicago, IL, USA. While at West Monroe, Dan's projects included designing high performing architectures for a variety of clients, as well as developing APIs and UIs for healthcare, insurance, and financial services clients. Along the way, Dan worked with .NET Framework, .NET Core, Java/Spring Boot, React, and Angular. He also gained experience with a number of database technologies, including DataStax, Cassandra, Microsoft SQL Server, Oracle, and PostgreSQL. Prior to joining West Monroe, Dan worked for a number of companies, focusing on .NET and Microsoft SQL Server development, including experience as a DBA.
Past speaking engagements have included PASS Summit, NDC London, NDC Melbourne, NDC Sydney, KCDC, Code PaLOUsa, and numerous SQL Saturdays throughout the US. Dan enjoys speaking at both large and small conferences, and values the interactions he gets with attendees and other speakers.
In his spare time, he can be found writing his own software instead of using package solutions or on the ice as an ice hockey player and referee.

ORMs and the DBA: How to Make Both Happy
DBAs lose sleep over ORMs touching their databases. Developers lose sleep thinking about using stored procedures. Is there a middle ground? Yes! I’ll introduce techniques and tools in .NET that let developers use ORMs while keeping the DBA happy.
Talk to any DBA about ORMs and you’ll quickly find out all the things you like about ORMs are what DBAs don’t like. Interestingly enough, most developers I’ve talked to have issues with their ORMs, too. In this session, we’ll explore why ORMs cause such trouble using examples of bad behavior and poor performance with common application patterns. I’ll outline some strategies for mitigating those troubles such as making sure to audit the generated SQL and changing how we write application code to take advantage of how ORMs attack problems under the hood. Lastly, I’ll introduce some tools (and even yet another ORM) that help solve some of the worst of the problems we see in the database when using ORMs.
How To Move Across the World and Lead a Team Without Losing Your Mind
Have you dreamed of moving to a different country? Experiencing life in a different place with different priorities? But what about making money, actually living, and the day-to-day that you take for granted in your current life.
In this talk, I'll reflect on my journey from the US to Denmark. I'll start with the planning, talk through finding a job (pro tip: networking is very important), and give an overview on the moving process. Next, we'll talk about how to settle in to a new role and a new country at the same time. Lastly, I'll talk about the strategies I've used to help assimilate and to address homesickness.
Is moving to another country a dream? Yes, and it can be a reality, too!
High Concurrency Table Hijinks
Do you have a high concurrency table? Something being used as a queue for your application or to track processing of data? This is a surprisingly common case in many large applications!
Come learn how we diagnosed (and solved) performance problems with a high concurrency table on software that serves 170,000+ customers! You'll learn what we did, how tracing and logging helped, and how we held a blameless post-mortem after the initial incident. While every challenge with high concurrency is different, the strategies for tackling it are similar.
Let's Get Scary and Continuously Deploy Database Changes!
Continuous deployment of our applications is easy! To roll back, all we have to do is just redeploy our old code and everything works again. Our application developers have been practicing these methods for years (even before the advent of automated CI/CD).
But...databases are much scarier - how do we undo data changes? What if we dropped (or shrank) a column? How do we handle downtime? Do we actually trust our application developers?
In this talk, we will discuss how to successfully automate database deploys as part of a CI/CD pipeline. We will address some of the stickier questions above, like how to handle data type changes and how to remove columns without losing access to the data. We will discuss automated testing in brief, and how it can help us avoid some of the messier problems. And lastly, we will showcase how to roll forward using both state-based and migration-based tools like SSDT or Flyway. We will use Azure for most examples, and the concepts will apply to (almost) any platform.
Testing! We're Talking About (Unit) Testing...Your Database!
Do you have business logic in your database? Is it tested? Do your developers look down their noses at your antiquated practices? If any of these are true, this session may be for you. In it, we will explore the different ways to test your database code without affecting your production database (or data). We will start with the basics of test case setup, followed by manual testing methods, and finish out with talking through tSQLt and how we can use it to automate our unit testing.
Entity Framework (Core) Unchained: Getting the Best Performance from Your ORM
Entity Framework makes data access in .NET applications as easy as defining some classes, adding a connection string, and writing some LINQ statements. But listen to developers and database administrators and you will find that taking the naive approach leads to poor performance, bloated databases, elaborate workarounds, and general dissatisfaction with the technology.
It doesn't have to be this way! Behind the simple facade, Entity Framework gives us multiple options for tuning our data access and improving performance. In this talk, you will learn configuration options and access patterns that can help improve performance. You will also learn what features in Entity Framework to use judiciously or avoid entirely. Next, you will learn some strategies for structuring your database in ways that both improve performance and simplify your application code. Lastly, you will learn some tipping points about when you should discard Entity Framework entirely.
SSDT, Docker, and (Azure) DevOps: How to Make Your Database Builds a First Class CI/CD Citizen
Your application developers benefit from Continuous Integration and Continuous Deployment practices to accelerate feature deployment and catch regression issues up front, but your database deployments are still stuck in the proverbial dark ages. The build scripts might be in source control or even an SSDT project already, but deploying is still an exercise in creating the perfect script, and don't even think about making a data (or data type) change!
SSDT and Azure DevOps can solve some of these problems, and even give us a window into the world of automated testing. In this talk, we will explore how to automate your database builds and deployments using SSDT and Azure DevOps, and we will explore automated testing using tSQLt and Docker. Lastly, we will check up on some tasks that you cannot (or should not) automate and talk about how to make sure your application developers are not left behind.
"What Do I Do? How Do I Do That?": Mentoring Junior Developers Into Productive Team Members
How do we make sure the Junior Developers on our teams contribute positively? How do we guide them into becoming the best developers they can be? Managing people can be hard, but I'll outline strategies to help mentor new developers while teaching them to be independent, positive contributors in any circumstance. Along the way, we'll talk about learning styles, the need to be open to any questions and how and when to explain versus when to simply say "you'll have to trust me for now."
These skills can be applicable in any project style or language, but we'll use Agile methodology and .NET languages for real life project examples.
