Jan 2024 – Present · 2 yrs 2 mos · Barcelona, Catalonia, Spain

As a Staff Engineer, I've led the integration of Sales, Product, and Engineering efforts, prioritizing feature rollouts, technical debt reduction, and best practice implementation. I initiated the creation of a dedicated Design System and component library to foster UI consistency and reusability across products.
My approach has embedded a product engineering mindset across our team, involving engineers directly in user research and metric-driven development, fostering a culture of rapid iteration and resilience. I've been instrumental in recruiting and mentoring top engineering talent, establishing a feedback-oriented culture that emphasizes continuous improvement and excellence.
Moving forward, my focus is on advancing our engineering frameworks to streamline product development, enhance cross-product interoperability, and drive innovation with efficiency at its core.
