Developing a SaaS doesn't have to mean:
Never-ending deadlines
Completely missed price estimates
Communication issues with your partners
An unusable SaaS due to budget constraints
If you think it always goes this way... Let me prove you wrong.
Let's TalkWhy trust me with your Software as a Service development?
A fixed budget with no surprises
I never provide a budget estimate before starting the project. This way, I can give estimates that are as close to reality as possible and avoid unpleasant surprises.Daily communication
Communication is the foundation of successful collaboration. My mission? To keep you informed of your project's progress while simplifying the technical aspects as much as possible. As a proactive partner, I'm here to advise you on the features to implement as a priority according to your SaaS objective.Agile development for maximum efficiency
I firmly believe in Agile development for your SaaS. This simply means that I deliver high-value features quickly and regularly. Adaptability is at the core of my work, and this directly impacts the satisfaction of my clients.Collaboration in French or English
I work daily in a bilingual environment, collaborating with clients worldwide. A collaboration in French or English? The choice is yours!Commitment to quality
I continuously test developed features using automated test to ensure your SaaS works correctly.More than just a freelance web developer!
My name is Sébastien, and I have been a full-stack developer for 5 wonderful years. Based in Maastricht, the Netherlands, I offer all my expertise to bring your SaaS project to life!
