A web application for managing audits, training and documentation.
OMS can integrate with other tools to make your audit process more efficient. Import and exporting data is just a click away.
NextJs
TypeScript
PostgreSQL
Django
TailwindCSS
Cypress
A brief overview of the features and how they will benefit the user.
Audits are used to check if the company is following the correct procedures.
The dashboard displays the status of the audits, the time spent training and the payscales.
The application is responsive and has a dark/light mode.
Here are some of the things I've learned while working on this project.
DRF provide me with an entry point to learn how to create a REST API. From serialization and authentication to pagination and filtering.
React(NextJs) taught me how to constantly reuse code, DRY, DRY. I learned how to use them and how to create a frontend for a REST API.
End to end testing was a new concept for me. I learned how to use Cypress to test interaction, components, intercept request and a lot more.
I learned how to implement responsiveness, dark/light mode. The beauty of TailwindCss is how fast can you create a beautiful design.
From AES/CBC encryption and Argon2 hashing to implementing encryption at rest, this project taught me a lot about data security.
No project is without its challenges. Here are some of the challenges we faced.
Since the data is sensitive, I had to choose an encryption algorithm that is secure and fast. We implemented AES CBC encryption to encrypt the data before it is sent to the database. For passwords I decided to go with argon2, which is a password hashing function that is designed to be slow to prevent brute force attacks.
This was a big challenge since we had to learn a new framework. I started with React and then moved to NextJs (loved NextJs). We had to learn how to create a REST API, how to serialize data, authenticate users, JWT, CORS policy, Swagger for documentation, and best practices for REST API.
Performance was an issue since thousands of records were being fetched from the database. Pagination, filtering and caching were implemented to improve performance. Endpoints were also optimized to reduce the data returned from the database. There was no need to pull all the data for no reason.
