In June 2020, in the midst of the COVID-19 pandemic, Oscar’s Senior Fullstack Engineer contract was cancelled. Oscar returned to his roots of constantly learning and pursuing educational opportunities, and used his now ample free time to hunker down and begin studying for the OpenJS Node.js Services Developer (JSNSD) certification exam he had purchased a few months earlier.
Oscar studied independently and practiced the skills listed in the domains and competencies for the JSNSD exam. After weeks of preparation he proceeded to schedule and take his exam, and was pleased to find his preparation work had paid off – he passed.
All the while, Oscar was job hunting. He was applying mostly for Node.js positions, but wasn’t having much traction; that changed though once he achieved the JSNSD certification and companies began noticing his profile featuring the achievement on both LinkedIn and Reddit. Oscar quickly was offered a position as Senior Backend Engineer, Node.js, at a health technology startup in New York.
Oscar says that the most useful part of the certification process for him personally was the practical knowledge he gained while preparing for the exam. The topics specified in the certification domains and competencies were especially helpful not only in preparing for the exam, but for his new job role. For example he learned about putting a strong emphasis on developing secure and reliable services using NodeJS, and how important it is to care about all aspects of our applications or services and not blindly trust they already have a strong and secure infrastructure, as that’s often when security breaches are found.
It’s also important for Oscar that he shares his knowledge and expertise with the community. For that reason he has started a developer blog and joined several groups on Reddit and Facebook focused on NodeJS, where he shares my experience and helps others with problems that align with his areas of expertise, including security, application structure, architecture and infrastructure for Node.js apps, including Docker and Kubernetes.
