WORK HISTORY
Staff Software Engineer @Dojo
London, GB
As a technical leader, I helped building the Reconciliation team, building it from the ground up through hiring, coaching, and mentoring engineers to deliver high-impact solutions. Collaborating closely with the Engineering Team Lead, Product Manager, and Engineering Manager, I provided technical guidance and helped shape the technical vision. Led the design and helped building a close real-time reconciliation engine leveraging an event driven architecture and Open Policy Agent (OPA) responsible to evaluate the correctness of an acquiring payment lifecycle, ensuring integrity from initial payment through scheme authorisation, clearing, and customer settlement.Collaborating with Staff Engineers to enhance engineering maturity and consistency across the tribe, I led the creation of a Technical Maturity Model, a framework for evaluating and guiding squads in adopting best practices, recommended tooling and engineering excellence across the tribe.On a broader scale, I championed cross-tribe initiatives, driving innovation through low-code frontend tools such as SuperBlocks and Retool. I led a proof of concept (POC), engaging Staff Engineers, Engineering Managers and the Head of Engineering in technical discussions to assess our approach. Working closely with the Platform Tribe, we successfully self-hosted Retool within Dojo’s infrastructure and provided ongoing support across the company.Passionate about knowledge-sharing and scaling technical capabilities, I led Tech Talks on key topics, including PubSub consumption scaling and MongoDB query performance, fostering a culture of continuous learning and innovation.

ABOUT PAULO CALDEIRA
Software Engineer for the past 13+ years where 8+ of these, I led and mentored cross functional teams building distributed systems using Cloud Native technology. I\'m a big fan of evolutionary architectures built using domain driven design which iteratively meet product needs over time keeping it maintainable and extensible with high observability at its core to help measuring how the system behaves and decide where to focus and prioritise optimisations, when needed. I have experience building low latency, consistent and highly scalable services using synchronous or asynchronous communications, triggering orchestrations or choreographies across one or multiple services. I lead the design of an extensible payments distributed platform across multiple self-organised teams which scaled from thousands to hundred of thousands transactions a day.
