Meet the Näktergal team building the data warehouses of tomorrow​

Recently, we chatted with the Näktergal Consulting team Fernando, Johan, and Henning. They tell us all about what it’s like to work here and what goes into building the data warehouses of the future. Read on to learn about our company culture and some of the fun things we get up to on the job!

Firstly, let’s introduce our team:

Fernando Soto Trujillo: Fernando is a system developer and has dreamed of working with computers since he was small. Fernando’s experience is in data warehousing, regulatory reporting, data vaults, and business intelligence. His passions include delivering solid implementations, automating designs of data warehouses, and helping customers achieve their vision. Fernando is an accomplished data modeller and has worked with a lot of different regulatory frameworks. In his free time, Fernando loves working out, spending time on his computer and watching movies. Particularly horror movies!

Johan Mannerqvist: Since 2012, Johan has specialised in data warehousing within the banking sector, focusing on regulatory reporting. He is passionate about data analysis and finding new solutions to data warehousing challenges. His expertise includes MS SQL & Integration Services. When not crushing warehousing problems, Johan likes cooking, gaming and spending time with his dog. 

Andreas Henning: Andreas is Näktergal Consulting’s CEO and is leading the way in building Näktergal’s future. Henning is exceptionally passionate about the vision, company culture, and, most notably, the tech. He is an experienced system architect working in the financial sector with data warehousing for more than a decade. As an expert in Data Vault modelling, he has written Näktergal Consulting’s software to automate the data warehouse design.

When it comes to the design and development responsibilities in assignments, Henning is hands-on and takes it in his stride. He is used to the differing department structures within FI’s. He is no stranger to working with both business and development teams. He is a certified Data Vault 2.0 practitioner and a SQL Server nerd.

It’s so great to have you all here. First, let’s talk more about you. What is your favourite part of your role? Why did you decide to become a consultant?

Fernando: For me, I became a consultant because I like the project-based aspect and the flexibility. I also think there is so much freedom to create. I love solving complex problems with the team – it’s an excellent opportunity to learn from the other consultants and discover new solutions. We go over the code and try to understand where it went wrong, and in the process, we learn new insights from each other.

Johan: I also think there are many opportunities to learn a lot on each new project, which is excellent. For me, I enjoy exploring our client’s systems and learning more about how they do business to understand better how I can solve their problems. For example, I recently worked within an extensive banking system, and I learned a lot about the business behind the products. In particular, I learned about advanced financial instruments such as credit default swaps and interest swaps. I think it’s essential to have insight into how the products work in practice because we can then apply that knowledge to create more intelligent, better models.

Henning: I like that there is a lot of learning on the job, too!

What do you think about the company culture here?

Johan: I think the culture is quite laid back. But we are ambitious in what we do. We know each other and know we can deliver all that the client expects. We trust each other, and that is crucial to the culture. We can afford to be laid back because we trust each other so much. 

Henning: We are still quite young but building the culture is part of the fun. There is a very collaborative culture here. Within Näktergal, there is a team of capable people that we can ask, each with their strengths and expertise. It is the dream to work in a culture where we help each other so much. In fact, cultural fit is hugely important to us. We don’t want any divas! It is important to us that the group likes and trusts each other. Of course, it is vital to have competence in their work, too, but team fit is a higher priority.

Let’s talk a little more about what you do. What do you enjoy about data warehousing?

Henning: It’s fun for me to build something from scratch and watch it get bigger, better and faster. When we start a new project we use our automation software, and our experience to build it into a model that can fetch data from many different systems. It’s also great because it allows me to be creative and develop new, better and better systems each time. We are constantly improving. 

Fernando: I like working with data warehousing because it’s like a puzzle – you need to put all the systems pieces together correctly to make sure the end picture comes out precisely. I also have much pride in my work – we create outstanding solutions here at Näktergal. It’s great to pass it to the bank/FI, knowing that they will be able to carry the system forward and maintain it themselves. 

Let’s get techy - what is important to you when building a data warehouse?

Henning: The system must be not only fast but also easy to understand. We like to use the acronym KISS – Keep It Simple Stupid – to ensure the structure of the warehouse can be understood by our clients. We never want to dump a system on a client and just walk away. Job done. We collaborate on the model and try to minimise back and forth questions. 

We also like to look holistically at the model and the software. We then combine this overview with our knowledge and our automation software, which dramatically reduces the time needed to deliver a warehouse. We can implement changes very quickly. This is a great USP for us. We typically create warehouses in 1/10th of the time relative to competitors because we have an intimate knowledge of their systems that most competitors don’t have. Plus, we have a clean conscience knowing that it is the best, most sustainable solution for our clients.

Henning, you mentioned Data Vaults. What are some of the advantages of Vaults over other techniques?

Henning: Data vaults are the best way to model a data warehouse. Vaults load quicker than other methods, without any risk of data loss. And a vault is excellent for growing as the business grows. Alternative approaches, such as using the Kimball system, are often very complex and costly. One of the most significant issues is that as the Kimball Data Warehouse grows, so does the complexity of the Data Warehouse. This leads to expensive and time-consuming processes that are not user friendly. Unlike Kimball systems, when a data Vault system gets larger, it doesn’t have to become more complex. Data warehousing and data vaults, on the other hand, give great value for businesses that are much, much faster to adapt. 

Finally, another one for our CEO. Henning, what is your vision for Näktergal consulting?

Henning: I want to grow the organisation. More of what we’re already doing but at a much grander scale, with roles carved out and a bigger team. 

I would also like to see us do large implementations, but we need to grow before doing those. We often see big banks putting so much money into their data warehousing projects, often with 10s if not 100s of employees working on it. Instead, we believe we can do it with just 10-15 Näktergal consultants. We have the vision to solve problems on a large scale, but we need to grow before we get there.

Thanks all. It’s been great chatting with you. Any last words?

Fernando: It is a great place to work as a consultant here at Näktergal. It’s ambitious, and we work hard, but we all enjoy what we do. We take pride in knowing we’re building our clients’ data warehouses the right way.

Henning & Johan: Agreed!
