I am a Mathematics and Computer Science major passionate about systems and their inner workings. As a developer, I have experience building backend APIs (Node + Express) backed by SQL or NoSQL databases, and consuming them with React or Angular client-side web applications. Even though I have used both functional and object-oriented programming, I gravitate more towards the latter (OOP) due to its capacity to promote scalability. I also used Test-Driven-Development (TDD) in most of my projects with Jest, Enzyme, Mocha, and Chai for unit and integration testing and Cypress for End-to-end tests. In addition to understanding the entire software development life cycle, I am also exposed to agile methodologies that enforce continuous delivery and allow distributed / remote collaboration. I am conversant with version control with my preferred system being git. Since I am self-driven, I flourish when working alone or in teams. My academic background made me appreciate and develop an interest in reading algorithms and using data structures to model real-life problems and develop solutions for them.Express Js
