Hi, I'm Valérian

I specialize in developing customized data infrastructures for small and medium-sized businesses, in order to boost their operations.



  Always intrigued by the idea of making machines communicate with each other, I have been coding since I was 12 years old. After a MSc in Network Engineering, I have worked in many organization as Software and Data Engineer and I continue to make systems communicate with each other.

  Today, I work with various companies to help them have their data in the right place, at the right time.

  I am a Data Engineer and Architect, which means I design and implement data infrastructures providing a reliable foundation for organizations to operate on.

  I also teach Python, JavaScript, and Object-Oriented Programming in several schools in my spare time.

Why me?

  • Gain insights into my methodologies and thought processes through my technical blog, where I share regular updates and in-depth analyses of my work.
  • Choose a path that prioritizes efficiency and personal attention. While larger companies may offer standard solutions with complex contract negotiations and varied timelines, I focus on delivering streamlined, high-quality services that are cost-effective and time-efficient.
  • In my practice, integrity is key. If I believe a particular technical approach isn’t the best for your business, I will be upfront about it. My goal is to provide solutions that truly benefit your business, not just to bill for services rendered.
  • I communicate and report at regular intervals, as much as daily if needed. You will always know where we are.

⚠️ - In order to minimize the delivery time for my clients, I limit the amount of client I have in parallel. Currently, I have 1️⃣ open slot.
