We have decommissioned legacy tools using near real-time event-driven micro-service
architectures (consuming events in the scale of billions during the peak season) using
Domain-Driven Design and TDD. We also took charge of some legacy tools, working on
maintenance and performance improvements.
I am responsible for defining each tool architecture and aligning our needs with the rest
of the company areas. I also identify architectural improvements, unblock dependencies
and chase issues that can have some sort of impact on our system.
I am also responsible for the team health: hiring, coaching, mentoring and building a
positive team environment.
