My Experience

Software Development Manager - Amazon Kindle 10/2021 – Present [Spain]

Software Development Manager of 3 different software development teams in Amazon Kindle, leading up to 2 SDMs and 25 engineers.

My charter owns the web reading experience at read.amazon.com (Kindle for Web - KfW), the sample reading experience in amazon.com (Look Inside The Book - LITB) and the native Kindle application for PC (K4PC).

As SDM of the charter, I supervise the performance of individual contributors and teams directly and through other SDMs, I work closely with the product team and with other engineering charters to align on the vision and deliverables, I optimise resources by aligning processes and technical stacks across teams and I deliver new features to delight our customers.

During my team in the team, we completely revamped the KfW experience (increasing by 20% the number of customers and 50% the number of pages read), redesigned the LITB experience to align with the rest of Kindle surfaces, and revamped the K4PC design and technical stack in order to re-use the web components of KfW.

Software Development Manager at Amazon Business 11/2019 – 10/2021 [Spain]

Software Development Manager of the Amazon Business' Customer Acquisition team in Madrid, in charge of the online registration for customers enrolling to Amazon Business.

I joined as the only member of the team in Madrid and I handled the recruitment and embarkment of 10 new SDEs, set up a team culture, defined best engineering practices, ensured operational excellence and handled the ownership transition of the Amazon Business Registration funnel from a team in Seattle to the new team in Madrid.

During my time in the team, we reviewed the entire registration funnel, revamped the entire frontend stack (from PHP to React), experimented with different approaches in order to reduce friction and launched new features to facilitate account verification. As a result, the successful funnel completion rate increased a 30%.

I follow up the career development and performance of each individual, manage external communication, handle conflicts and make sure the team engagement and motivation is kept high.
