Freelance Data Engineer
Good data engineering makes good business achievable. Data platforms and products need strong engineering, good workflows, and team support. You need a senior professional architect to build, test, and deliver infrastructure-as-code, clear architecture on cloud and code levels, with DevOps, CI/CD, and a good helping of common sense. I can help.
With broad experience in data engineering, experience building data platforms and products across the three major clouds (Azure, AWS, and GCP), I can deliver not just the technical skills but more importantly, the infrastructural knowledge to deliver a best-fit solution for your organizational, data, sustainability, and productivity goals. Let's talk about how I can solve your problems.
From my clients
"Josko is not only a very good and productive data engineer and also a very smart guy. He is also a great team member: during a retro, he addresses the weak spots of the way of working; he is very keen on (and good at) sharing his knowledge, both in team sessions as in 1-1 meetings. " - Erik Volkers, Randstad Groep Nederland
"I had the pleasure of managing Josko de Boer at Spil Games, and he stood out as a data engineer with an exceptional focus on quality. He consistently took the time to understand the problem from a stakeholder perspective, ensuring that the solutions he built were not only technically sound but also truly valuable to the business. This was crucial when building out the AB testing platform for the company which had several key stakeholders with different requirements. Josko has a great ability to work independently while keeping alignment with the team’s direction, making collaboration smooth and efficient. He also genuinely cares about his colleagues, always willing to support and share knowledge. Any team would be lucky to have him! " - Natalie Selin, Co-founder and COO Pointless Games
"Josko is an amazing data engineer and then some. He is always doing his best to look at the best way that the business would benefit from the data. He can connect the business wishes with technical solutions and can understand the impact of the things he is working on." - Richard Ramcharan, SpilGames
"Ik heb met Josko samengewerkt tijdens zijn opdracht bij Alliander. Daar heb ik hem altijd ervaren als een pragmatisch engineer met een "can-do" mentaliteit die snel complexe vraagstukken rondom infrastructuur aanpakte. Daarnaast viel zijn scherpe oog voor de bedrijfspolitiek me positief op, wat hem hielp om snel de relevante collegas binnen het bedrijf te vinden. Ik kijk ernaar uit nog eens met Josko samen te werken!" - Thijs Nieuwdorp, Author of Python Polars: The Definitive Guide
