Introduction:
As a full-stack developer intern at Horizon Labs, I had the opportunity to work on a project where I was responsible for building the company’s display website. I created the website’s frontend and backend using the MERN stack, which consists of MongoDB, Express.js, React, and Node.js. In this blog, I will discuss my experience working on this project, including the challenges I faced and how I overcame them.

MERN Stack

Creating the Frontend:
Once I got the wireframes, mockups and prototypes from the graphics designer, I started building the frontend using React. I used various libraries such as Bootstrap and Reactstrap to make the website responsive and easy to navigate.

Challenges Faced: One of the main challenges I faced when building the frontend was making the website responsive across different screen sizes. I had to ensure that the website looked good and was easy to use on both desktop and mobile devices. To overcome this challenge, I used responsive design techniques such as fluid layouts, media queries, and flexible images.

Creating the Backend:
After completing the frontend, I moved on to the backend. I used Node.js and Express.js to create an API that allowed the frontend to communicate with the database. For the database, I used MongoDB and implemented features like CRUD operations and pagination to manage the products and user data. I also implemented authentication and authorization features to ensure that users could only access their own data.

Challenges Faced: One of the main challenges I faced when building the backend was handling large amounts of data. There were instances when a lot of data transfer was supposed to happen without any delays. To overcome this challenge, I used indexing, caching, and pagination techniques to ensure that the website remained fast and efficient even with a large amount of data.

Another challenge that I faced when creating the API was ensuring that it was secure and scalable. I had to implement various security measures such as input validation and encryption to prevent attacks like SQL injection and cross-site scripting. I also had to design the API in a way that could handle a large amount of traffic and scale as the website grew.

Collaboration and Agile Development:
Throughout the project, I worked closely with other developers and designers at Horizon Labs. We followed an agile development methodology, which involved working in sprints, holding daily stand-up meetings, and using project management tools like Jira and Scrum like Trello to track our progress.

Challenges Faced: One of the main challenges I faced during collaboration was communicating effectively with team members who had different backgrounds and skill sets. To overcome this challenge, I made sure to document my code and communicate clearly and regularly with my team members.

Conclusion:
My internship at Horizon Labs provided me with valuable experience in creating web applications using the MERN stack. I gained experience in building both the frontend and backend of a web application, as well as managing a database and implementing various features to enhance the user experience. Through this project, I learned about agile development methodologies and how to collaborate effectively with a team. The challenges I faced during the project helped me grow as a developer and gave me valuable experience that I can apply to future projects.
