Strategic focus: I led an engineering unit with highly fragmented scope. I brought in a strategy and transparency of deliverables, finalized and sunsetted low-impact solutions, optimized the team and overly formal processes, keeping high internal customer satisfaction. I involved engineers and team squads into ownership, self-optimization, and rotating team leader initiative. Over a short period of time I grew 3 team leaders and 3 new engineers, all successfully contributing to the team.Engineering focus: I delivered a set of production-grade tools for effective mapping and data management with high availability, scaling the operators’ team productivity up to 5x depending on the project. Among the multiple supported domains were execution, managing expectations, and the delivery of the high-risk / high-yield Autopilot Map tooling.
