Sander in a few words

14 years of experience as IT lead. Passionate about the development of software, teams, and products.

I am available for:

Solution Consultancy

As a solution architect I can bridge the gap between business needs and IT-requirements. I am a good communicator and able to keep oversight over complex infrastructure and business domains. I also possess the necessary technical skills for the actual implementation.

Software Development

As a senior software engineer, I am focused on delivering value to customers and users. I keep long term objectives in mind by holding myself to a high-quality standard resulting in maintainable, reliable, performant, and secure code. Agile and DevOps principles are running in my blood. In my collaboration with team members I am constantly trying to learn from others and coach peers in becoming true craftsmen. I love programming in Golang . It is a powerful tool on so many levels that has enabled me to deliver value fast on multiple occasions.

Also, I love refactoring legacy PHP codebases which are stuck in the previous century. I am able to transform unstable and unmaintainable applications into something that can be built upon in the future, enabling businesses to innovate, grow, and deliver on promises.

I have all the skills needed to do full-stack development, a broad knowledge of Linux, and experience with a wide range of software products including PostgreSQL, MongoDB, ElasticSearch, RabbitMQ, and many more.

DevOps coaching

Creating collaborative teams is more important than attracting rockstar programmers. I can help in agile transformations and beyond. DevOps is not just having a CI/CD pipeline. It is about knowing where value is delivered and then continuously improve upon that delivery. A fresh look might reveal hidden waste and increase the reliability and efficiency of your service delivery.

Experience

Ingenieursbureau IB BV

Software Publishing

Technical Director

Eindhoven, Netherlands

October 2019 - July 2022 (2 years and 9 months)

During almost 14 years at IB I've been responsible for all IT related matters, from the start-up phase, up until company adulthood. I've worked with numerous people on both long- and short-term projects. I've successfully implemented the Scrum methodology in our organisation and was involved in product development on both a strategic and operational level. I've taken responsibility for the security, stability and flexibility of our IT ecosystem. I've coached and challenged multiple people in becoming true craftsmen in software engineering and most of all I've enjoyed seeing products, people and the company as a whole grow.
