Tim Cools is a seasoned software engineer with 12+ years of experience building scalable, event-driven back-ends, distributed systems, and high-performance architectures across .NET and JavaScript ecosystems. He has led architecture and teams, migrated legacy systems to cloud-friendly, CQRS/Event Sourcing designs, and contributed backend/database engineering work to notable open-source projects like Marten (a .NET transactional document DB on PostgreSQL). Equally at home profiling low-level performance issues as he is designing CI/CD, automated testing and resilient message-driven systems, Tim pairs hands-on coding with mentoring and architecture. Outside software he is a long-time electronic music DJ/producer and party organizer since the 1990s, bringing a creative, community-oriented mindset to his technical work. He also founded a psychedelic community resource and taught mindfulness, reflecting a commitment to wellbeing, harm reduction and inclusive communities.
