Recommendations
I worked with Gerardo on several different projects at Backcountry, his skills to deliver high-quality software allowed us to put into production solutions that in other occasions would have been impactful to the business and our customers, he thinks in stability, performance, security, and incremental rollouts. He was able to do so by technically leading the ERP go-live for the Company in regards to Product Data and Purchase orders, these integrations had zero impact on the overall put into production. Additionally, Gerardo led the design and architecture of a new Email Service Provider for the company, he engaged with stakeholders, worked on yet another seamless deployment and was the go-to person for both stakeholders and engineers, he is a person that rapidly engages and understands the technical and functional needs, he builds software that delivers value as soon as possible and then iterates on it to guarantee the quality is there for the long term, running chaos testing, load testing and always looking for design and stability patterns to be present.

Gerardo and I worked together in the Marketing, Merchandise & Content Software Team from November 2016 until April 2020. In that time Gerardo emerged into a strong leader who greatly influenced the improved quality of our code and processes. This was illustrated by his constructive feedback in code reviews, his mentorship of newer team members, and his self-started project to standardize logging, metrics, and dashboards across a number of our systems. His project, dubbed ‘Logging & Monitoring’ was critical for our team during high-demand times (such as Black Friday) and enabled us to quickly identify and resolve issues before such impacts became devastating.
In addition to his technical capabilities, I must highlight Gerardo’s exceptional character and reliability. He was a teammate that could always be counted on, evident by the many long, stressful nights and projects and war rooms in which he participated. He was always in the trenches, ready to jump into the fire, not just because he felt responsible for the systems but also because he felt responsible for the health and morale of his team.

Services
Backend development
Creating and maintaining RESTful APIs with a variety of frameworks like Spring Java, Play Scala, Python Flask and ASP.NET
Web Development
I give maintenance of websites and dynamic applications in JavaScript, JQuery, AngularJS, Node.js, Bootstrap, HTML5, and CSS3. Also, acquaintance with CMS like WordPress and Liferay.
Databases
I'm accustomed to SQL in relational database systems like Oracle PostgreSQL, including non-relational like MongoDB, with its aggregation framework.
Containerization
I'm comfortable working with Docker as the containerization platform and Kubernetes as the container orchestration platform.
CI/CD
When it comes to continuous integration, I used Git for my version control; I have created the Jenkinsfiles for Jenkins to generate the artifact. I've applied a dev, stage, and production environment in conjunction with Spinnaker for continuous delivery.
Performance Testing
I proposed an initiative of standardize Dashboards for monitoring and alerting in Sumologic for the backend teams; the next step was to automate load testing with Gatling and chaos testing with Gremlin inc to ensure the performance of the APIs.
Agile Methodologies
Different situations call for different methodologies; scrum is my default methodology because of its timeboxing property. When the workload increases, I have switched to kanban to keep with the fast pace.
OOP Best Practices
I know how and when to apply design patterns, encapsulation, and SOLID principles, a fan of clean code, practice TDD, and on Code Reviews, I always support myself with the source.
