David Decosta Email & Phone Number

I graduated from Fairmont State University with a Bachelor's in Computer Science and a minor in psychology. I find great fulfillment in the challenges and rewards of programming, particularly in the art of deconstructing complex problems into manageable sub-problems. This skill not only serves me in the programming realm but has also become a general approach in my daily life.

I used NPM as my package manager, including the Heroku CLI, and utilized Git for version control and deployment on both GitHub and Heroku.𝙲𝚑𝚊𝚝 𝙿𝚛𝚘𝚓𝚎𝚌𝚝- I developed a two-component chat application, comprising a server and client module, coded in java. The functionality of this application extends to user registration and login capabilities, along side users being able to add/remove friends and engage in real-time conversations. This project highlights my ability to design and implement interactive applications and setup protocols.
