As systems evolve, they become more and more complex, with unpredictable and often unexpected behaviour. Message metadata can enable true observability and allow us to use system behaviour to firstly understand, but also debug our system.

Savvas is the head of engineering for ParcelVision ltd, and has worked on highly scalable, high performance, evolvable systems in industries such as financial services, telecoms, entertainment, gaming, health and transportation. Through different positions as tech lead, and architect (and sometimes both), he helped companies solve complex problems by applying process changes, collaborative discovery, design workshops, architecture, and implementation of sociotechnical systems. Savvas has significant experience with DDD, CQRS, and Event Sourcing and has delivered and (perhaps more importantly) maintained such solutions in production.
