About Me

Web3 Technical Ambassador & Community Builder

Hi, I’m Rafiq Ahmed, known in the crypto space as Berlin. I’m based in Lahore, Pakistan, and began exploring blockchain technology after completing my Intermediate in Computer Science (ICS). With over seven years of experience in the Web3 ecosystem, I’ve built a strong foundation in decentralized technologies, actively contributing to community growth and infrastructure development.

Currently, I’m a Technical Ambassador at Redbelly Network, where I assist with validator operations, technical education, and community engagement. I also serve as a Community Moderator for both Privasea and Helix Labs, where I support users and help nurture thriving ecosystems. Previously, I held the role of Technical Ambassador at NuLink, promoting secure, privacy-preserving solutions in the decentralized space.
