How can Propellant help you?

Data engineering

Do you face hard Data Engineering & Data Management problems?

Propellant will analyse your data problem and propose a solution that will be sustainable. We will build and integrate this solution and provide hand-over to your internal team(s), if needed. Managing data streams, ETL’s, heterogeneous data storage platforms.

Scalability and performance

Is the scalability and/or performance of your software (components) lacking?

Propellant will analyse your architecture for scalability and performance bottlenecks, investigate and profile your implementation and provide you with actionable suggestions to remove the bottlenecks. We can also rework critical parts or components to match your performance and scalability needs.

High availability

Do you lack the experience to build distributed and highly available (HA) software solutions?

Propellant’s real-life experience with building distributed and highly available systems will make sure that you don’t have to go through the long and expensive process of experiencing all the ways in which an improperly designed system can and will fail.

Building teams

Are you trying to kickstart your internal development teams?

Propellant will bootstrap your development approach with a comprehensive set of best practices and support you with senior architecture and development advice.


Would you like you or your team to get more insights into the data engineering problems you will encounter?

Propellant will come on site for a workshop focussed on avoiding or managing the biggest pitfalls in data engineering. This includes problems you will notice early on but also potential future problems that will become expensive to solve when not tackled early on.
