Mongoose query documents with matching array element thumbnail
As a NoSQL database, MongoDB can store arrays as fields of a document. This article presents how to query such documents by filtering those with arrays that contain a specific value.

Wardrobe and outfits management web app

Have you ever bought a piece of clothing only to come home and realize you already had a similar one in your wardrobe? This happened to me the other day so I decided to fix the problem. To do so, I designed a simple web application in which the user can keep track of all the garments they own.

Food manager

The other day, I found myself putting on some weight. This rather surprised me as I thought I was having a healthy diet and exercised almost daily. To identify the root of the problem, I decided to start measuring my calorie intake as well as the macronutrients that constitute said intake.

Camera viewer

IP cameras are cheaper than ever and with the ESP32-CAM boards it is now possible to stream video for less than USD 10. However, IP cameras are commonly either only accessible from within their network, or use servers from third party companies to allow users to see the video feed from anywhere in the world. As both scenarios are inconvenient, I decided to create a camera viewer application that can proxy the video feed to a web interface.

User management and authentication service using MongoDB

User management and authentication service using MongoDB thumbnail
More often than not, web applications require restrictions regarding who can access the content that they serve. This involves an user management and authentication system, which, if designed inappropriately, can lead to security concerns. However, the development of such system can be time consuming, especially if done repeatedly for multiple applications.

Many companies rely on spreadsheets to keep track of their fixed assets. However, spreadsheets are commonly designed to be edited manually, which makes automation difficult.

Image upload microservice

An image is worth a thousand words and probably even more if comparing their size in bytes. When designing my CMS, I originally intended to store images directly in the article, encoded in Base64. However, this would considerably increase the size of each article, making the whole CMS slow.

Cashless payment system

Cashless payment system thumbnail
A company I worked for had a coffee machine for which employees could purchase coffee. However, the payment was done by putting coins in a jar. Not only did this present the obvious risk of theft, this system was also impractical for people not carrying spare change at all time. I decided to solve this issue by designing this cashless payment system.
