Developer experience

I value the importance of clean and efficient source code in streamlining development and accelerating project delivery. With expertise in Azure and GitLab, I have successfully implemented automated pipelines for seamless code integration. These automated pipelines have significantly reduced the need for repetitive manual actions, allowing developers to allocate more time to the enjoyable aspects of our work.

My preference lies in writing automated tests, including unit, integration, and contract tests, as opposed to manual feature testing. By doing so, I ensure thorough validation of software functionality, minimizing the risk of errors and increasing overall reliability.

I actively stay updated on industry best practices, regularly exploring new tools and frameworks to optimize code efficiency and quality.

Solution Design

Throughout my experience, I have actively contributed to the design process of comprehensive solutions, including microservices and APIs. Each of these endeavors presents its own unique challenges. When designing a complete solution, it is crucial to grasp the current state of the business, its expectations, and future visions, and adapt the solution to align with the teams responsible for its development.

In the case of designing an application, I believe it is paramount to have a solid understanding of its domain. This understanding enables the definition of clear responsibilities and ownership of data within the service. Additionally, considerations such as the infrastructure and the deployment process play a significant role in the overall solution design. Factors like self-hosted web servers without containerization, self-hosted Kubernetes clusters, or utilizing DevOps platforms such as Azure, AWS, or GCP can greatly influence the architectural choices and overall solution approach.

I am highly aware that there are situations where multiple possible solutions exist for a given challenge, and it can be challenging to choose the best one when no option stands out as significantly superior or inferior based on the considered criteria. Recognizing these situations and making informed decisions is of utmost importance, and I have developed the skills to navigate such complexities. By maintaining awareness of these critical aspects, I ensure that the solutions I design are tailored to the specific requirements.
