Nicolas Brulay
Founder, Ball Lightning AB
I am a project manager and full-stack developer with shipped work across MMOs, clinic websites, enterprise data systems, blockchain integrations, and integration-heavy product delivery. I work full-time at Hultafors Group as Product & Service Owner - Integrations. My focus is integration ownership: modernization, harmonization, strategy, AI, automation and the technical shape of how integration capabilities evolve over time. Ball Lightning AB remains maintained as a company presence, portfolio and archive for selected previous work, but I am not currently accepting new client engagements through it.
