Job Summary: RSVZ is a national institute that deals with social security matters for selfemployed entrepreneurs. My role here was to maintain the in-house software that is used to

follow up on said social matters. For my team specifically, the scope is set to all matters

regarding pensions.

Throughout the last year of this engagement we have developed a platform that retrieves,

processes and evaluates large amounts of self-employment data from many different

services, with a strong emphasis on performance and scalability. I was given a lot of

responsibility for this project, and I am very proud of the simplicity we have been able to

maintain amidst the complex requirements we were given along the way.

Tech Stack: .NET Framework, .NET Core, WPF, Entity Framework, WCF (SOAP), IIS, OracleDB, Azure DevOps, Git, MSTest, Agile, NServiceBus, BenchmarkDotNet, Blazor

Job Summary: Lansweeper is a Network Discovery Suite designed to be the ultimate all-inone solution for network architects. I joined the Discovery 2 team, which was one of three

teams in charge of adding and maintaining different methods of device discovery on IT

networks.

A couple of months after I started, Lansweeper started developing its VNext solution, in

order to update the codebase to current standards and practices. With this change, I was

put into a two-person team in charge of the Hub, which serves as a central entity on the

network that gathers data collected by Sensors on the network and funnels it to the cloud. I

was quick to point out that our OT-solution was so similar to the IT-solution that it made no

sense to develop and maintain two Hub projects separately. As such, these Hubs were

merged into one code-base and our two-person team was re-merged into Discovery 2.

Within the VNext context, this team now focussed on development for Windows and Mac

OS.

Tech Stack: .NET Core, Entity Framework, MassTransit, ASP.NET MVC (REST), (Mud)Blazor, Git,

CircleCI (CI/CD & YAML), Azure, MSSQL, SQLite, NUnit, Agile

Project #1 Summary: Before my first assignment, I was given a practice-project which

introduced me to Dependency Injection and N-tier architecture in a relatively simple CRUD

web-application. At a later stage I also had to implement RabbitMQ.

In March ’20 I rolled into an ongoing project at Bayer’s Crop Science Division, formerly

known as Monsanto. The scope of this project was the development of an MES platform,

mostly catering to the factory workflow of corn seed production. The platform covers the

seeds’ journey through the factory from the silos to the packaging process and serves as a

specialized extension of Siemens’ Opcenter platform. Once completed, Bayer planned to

deploy this platform to all its sites worldwide. As such, the project was very international in

nature, employing technological profiles allover the world, including but not limited to

Belgium, Scotland, Italy, Germany, Brazil and North America.

Tech Stack: .NET Core, Entity Framework, ASP.NET MVC (REST), NUnit, MSSQL, Siemens

Opcenter, Git, Agile

Project #2 Summary: In January ’21 I was added to a very similar ongoing MES project at

Actemium. The main difference with Bayer’s project was the technology stack. Their

platform was to be a replacement of an outdated Oracle Legacy System. As such, the

project was developed DB-first using in-house databases and software, rather than using

intermittent software like Siemens OpCenter.

Technologies used: .NET Core, Entity Framework, ASP.NET MVC (REST), NUnit, Oracle DB,
