Day 1:

Today was my first day as an intern at a software company where I will be working with Java SpringBoot. I started by familiarizing myself with the company’s codebase and the SpringBoot framework. I also spent some time setting up my development environment and configuring it to work with the project.

Day 2:

I continued exploring the codebase and reading through documentation on how different components of the system work together. I also attended a meeting where we discussed the overall architecture of the application and how it fits into the larger ecosystem.

Day 3:

Today, I worked on implementing a new feature for the application. It involved creating a new endpoint in our REST API that would allow users to retrieve data from a third-party service. I had to research how to make HTTP requests using SpringBoot, as well as how to parse JSON responses.

Day 4:

I continued working on the feature from yesterday, this time focusing on error handling. Since we were relying on an external service, there was always a chance that something could go wrong. I learned about SpringBoot’s exception handling mechanism and implemented it to return appropriate error messages to clients.

Day 5:

I spent today reviewing my code from earlier in the week and making sure everything was properly documented and tested. I used JUnit to write unit tests for all of my new code, which helped me catch some bugs before they made it into production.

Day 6:

Today was spent working on optimizing one of our existing endpoints. It was taking too long to return data for certain queries, so I had to dig deep into our database schema and query patterns to find ways to speed things up. In the end, I was able to reduce response times by over 50%.

Day 7:

On this Saturday, I decided to spend some time learning about Spring Security - an important component of any web application that handles authentication and authorization. There were a lot of moving parts to understand, but I was able to create a basic implementation that protected our endpoints and required users to log in.

Day 8:

I continued exploring Spring Security today by adding support for OAuth2 authentication. This would allow users to log in using their Google or Facebook credentials instead of creating a new account on our system. I had to go through the process of setting up API keys and configuring the OAuth2 client, but it was rewarding to see everything come together.

Day 9:

After spending most of last week working on backend features, today I shifted my focus to the front-end. Our application used AngularJS for its user interface, so I spent some time reading up on best practices and creating a simple component that displayed data from our API.

Day 10:

I continued working on the AngularJS component from yesterday, this time adding support for pagination and filtering. It was interesting to see how the front-end interacted with the back-end REST API and how easy it was to integrate them using SpringBoot.

Day 11:

Today was spent addressing feedback from my mentor on some of my earlier work. He pointed out some areas where my code could be improved, such as better exception handling and more efficient database queries. It was humbling but helpful feedback that will make me a better developer in the long run.

Day 12:

I took a break from coding today and attended a tech talk given by one of our senior engineers. She talked about how we use Kubernetes to manage our deployment pipeline and ensure scalability and reliability across multiple environments. It was fascinating stuff that gave me a better appreciation for all the work that goes into making complex software systems function properly.

Day 13:

Back to coding today! I worked on implementing caching for some frequently accessed data in our system. This involved using SpringBoot’s caching annotations to cache query results in memory, which resulted in much faster response times for clients.

Day 14:

Another day, another feature to implement. Today I worked on adding support for file uploads to our API. This involved using SpringBoot’s multipart handling capabilities and configuring our server to accept large files without crashing or running out of memory.

Day 15:

Today was a big day - we merged my changes from the past two weeks into the main branch of the codebase! It was exciting to see my work go live and be used by real users. Of course, there were some bugs that cropped up that needed to be addressed, but it was a great feeling overall.

Day 16:

I spent today working on bug fixes related to some of my earlier work. It’s always a bit frustrating when you think you’ve solved a problem only to have it come back later, but debugging is an important part of software development.

Day 17:

I started working on a new feature today that would allow users to schedule reminders for certain events in our system. This involved creating a new database table and integrating with an external service that would send out email notifications at the appropriate times.

Day 18:

Continuing with yesterday’s work, I had to figure out how best to store and retrieve scheduled reminders from the database. There were a few different approaches I considered (such as using cron expressions), but ultimately settled on storing them as timestamps in UTC time.

Day 19:

I spent today writing tests for the reminder functionality I implemented over the past few days. Since this was a relatively complex feature with multiple moving parts, it was important to make sure everything worked as expected before merging into production.

Day 20:

Weekend again! I decided to spend some time brushing up on my Java skills by doing some online coding exercises. It can be easy to get caught up in one particular framework or technology stack, so it’s good to take a step back sometimes and focus on fundamentals.

Day 21:

Back to work. Today I worked on integrating with a new third-party service that would allow users to upload images and other media to our system. This involved creating a new API endpoint and using SpringBoot’s file handling capabilities.

Day 22:

I spent today working on more caching optimizations for the API endpoints that were frequently accessed by clients. By storing commonly requested data in memory, we were able to reduce response times even further.

Day 23:

Today was spent addressing some performance issues related to our database queries. We had noticed that certain operations were taking longer than they should, so I had to dive deep into our schema and indexing strategies to figure out how best to optimize things.

Day 24:

More bug fixes today! It seems like every time we fix one issue, another one pops up somewhere else. But that’s just part of the job.

Day 25:

I spent today working on documentation for some of the features I implemented earlier in the month. It’s easy to forget how much effort goes into writing good documentation - it can be tedious at times but is essential for making sure everyone on the team understands how everything works.

Day 26:

Another feature request came in today - this time, we needed a way for users to leave comments on certain items in our system. I had never worked with comment functionality before, so it was an interesting challenge figuring out how best to store and display them.

Day 27:

Continuing with yesterday’s work, I implemented a basic commenting system that allowed users to add and delete comments on specific items. There were some tricky edge cases (such as handling simultaneous updates from multiple users), but overall it went smoothly.

Day 28:

As always, there were bugs that needed fixing after merging my changes into production last week. One of them involved race conditions when updating certain fields in our database - it required me to use SpringBoot’s transactional annotations to ensure consistency.

Day 29:

I spent today working on improving our error handling for certain API endpoints. We had noticed that some clients were receiving vague error messages when something went wrong, which wasn’t helpful for debugging. By providing more detailed information in our responses, we were able to make it easier for developers to track down issues.

Day 30:

Today was a bit of a break from coding - I attended a workshop on Agile software development practices and how they’re implemented at our company. It was interesting to see how different teams approached things like sprint planning and retrospective meetings.

Day 31:

Back to work! Today I worked on adding support for internationalization (i18n) in our front-end code. This involved using AngularJS’s built-in i18n features and translating all of our UI text into multiple languages.

Day 32:

Continuing with yesterday’s work, I started looking into how best to handle date formatting across different locales. It turns out this is a complex problem with no one-size-fits-all solution, but by using Java’s built-in Locale class and SpringBoot’s message source functionality, we were able to come up with something that worked well enough.

Day 33:

Another bug fix day - this time related to an issue where some users were seeing stale data even after making updates. It turned out that we weren’t properly invalidating the cache when changes were made, so I had to go through and update all affected endpoints accordingly.

Day 34:

I spent today working on refactoring some legacy code that had been causing issues recently. This involved re-architecting certain parts of the system and updating dependencies to their latest versions.

Day 35:

My final day as an intern! I spent most of it writing up my findings and recommendations from the past month - things like areas where we could improve performance or refactor existing code for better maintainability. It was a good exercise in summarizing my work and reflecting on what I learned.
