During my career I manage a large number of projects, but one of the most challenging ones was the development and launch of a Telematic Control Unit for an important car maker in Japan. The project is important to me due to technical challenges we faced, the skills I applied and the impact on the company.

As Program manager my role was to lead a cross-functional team including Design Engineers, SW Engineers, Operations teams, Material procurement teams, quality and logistics, among others to successfully launch the product to mass production.

First, I kicked-off the project. For that, I shared with the team the project scope, the goals to achieve, I shared the project plan with key milestones and defined the roles and responsibilities for the different team members.

During execution, to maintain a clear communication, I set up design review sessions with the entire engineering organization to ensure everyone was aligned and fixing potential issues in advance. Besides, I led a weekly core-team meeting where we assigned tasks to team members, and setting clear deadlines for each task. To make these tasks easier to manage, I made sure tasks were broken down into manageable sizes with clear descriptions and acceptance criteria. This helped the team to stay focus on their deliveries and maintain speed.

Another important part was to manages Risks. I worked with the team to identify and classify possible risk that might impact to the project deliverables. We defined a Risk matrix to monitor during the development process, and also a project board with the main KPIs to achieve during each stage of the project.

To ensure quality, we defined different testing processes focused on the design, and the process. We installed specific quality check for the documents and devices delivered for each of the milestones of the PDP, as well as a clear quality control in mass production.

Finally, for transparency, I reported on monthly basis to our company leaders and customer about the project status, focusing on Timing, cost, quality and scope.

By employing these strategies, we successfully launched our module on time matching with all the requirements defined by our customer. This was a great example of teamworking, and taught me the importance of breaking down large projects into smaller and easy to manage pieces. Transparent and clear communication was also a great lesson learned. This approach helped me to improve in leading teams through complex problems.

I would like to talk about situation. When I was an engineering  manager at digital commerce platform org at Amazon, I was handling close to 11 services, and 

as part of the Rolling Stone initiative where Amazon was trying to move all its services away from Oracle, I had four services that I was trying to migrate from Oracle to the databases hosted on Azure. All my fellow colleagues who were owning services of DCP were doing similar exercise. One of the colleague who was owning digital redemption service had to go on maternity leave, and then couple of engineers earmarked to do this migration for digital redemption service wwere transition out of the organization. That is when I offered to help with the migration of the service. 

So I now had 5 services with competing  priorities where I 

had to manage very tight schedule of service migrations. Planning a very ruthless prioritization, figuring out an optimal execution path of a completely unknown service, interacting with the service upstream clients whom i had not worked with prior, working with an amalgam of My team members and the service owner team members were few of the ambiguous paths I navigated to help do on time migration completion of the   service owned by my collegues.

It would be at my thesis, of predicting SEPSIS with AI using multiple models, and the challenge was with time management, since we had 2 problems, the first problem was that we didn't had access to the data base until half of the second semester, since the process to get access to a hospital database was a rigorous process, so we weren't able to go quick with our application. The second one was that a team mate and I had a family member with cancer, so we needed to manage our work load in a manner that we could be present as family and team members, we needed to fulfil our duties on the project, so I planted a prioritization process in witch we focused on our best attributes I on sql queries and documentation, mostly but the situation with the family member of my companion worsen, so needed someone to help with his work load, so I also assisted him with his main tasks as the main designer of the project, mainly on the uml diagrams, so that we could end our thesis
