Over mij
My work has helped generate over $100 million in on‑chain value across more than 70 projects. I’m Karim, a blockchain engineer based in the Netherlands.
I partner with two types of clients:
• Non‑technical founders who want to launch and scale Web3 products without worrying about security or delivery.
• Technical teams who are strong in Web2 but need deep, battle‑tested Web3 expertise to ship secure, production‑grade blockchain features.
My role: be the Web3 lead you trust with the architecture, security, and implementation so you can focus on users, growth, and capital.

Absolutely fantastic experience working with Karim! From the very first message he made it clear he knew exactly what we needed and how to get there. The tool he built was clean, worked first time, and he kept us updated the whole way through without us ever having to chase him. Honestly one of the smoothest...

Communication with Karim was clear and responsive throughout the whole project, and he made sure expectations around the HubSpot integration and dashboard scope were well defined from the start. Any questions I had were handled quickly, and the final build came out exactly as discussed.

The advisory session was delivered on schedule and covered all agreed scope, including account health scoring logic, configurable playbook architecture, and a prioritized implementation roadmap. Overall, the engagement was handled with professionalism and technical precision, and the output is directly actionable for our next build phase.

Karim was easy to work with and communicated clearly throughout the project. He delivered what was agreed on and handled feedback well. The AI coach works as expected and fits our initial goals. Would work with him again.
