Accomplishments
Project: Event management website development
Objective: Our project object is to develop an event management website that will assist individuals in organizing and arranging their events. Because this project is all about innovation, we did incorporate all our ideas to make it more appealing to users. This is the sole method for clients to identify our work, and it is our responsibility to design our website in such a manner that it is both trustworthy and user-friendly. We chose this project since it allows us to develop additional features and has high market demand. Aside from that, it has a lot of potential for future growth. Tools like HTML, CSS and bootstrap were used for developing the front end while back end was developed with python, Flask, MYSQL, xampp and phpadmin.
Project: Sending Emails to users using AWS cloud
Objective: Our project focused on developing a robust file storage system using AWS S3, a secure
and scalable cloud storage service offered by Amazon Web Services. By harnessing the advanced capabilities of AWS S3, we ensured efficient and reliable file storage. To improve usability and accessibility, we implemented a dynamic process that generated unique website URL links for each file. These links served as direct pathways to the stored files, enabling users to conveniently access and download them.
