Group management microservice
As a graph database Neo4J is a great choice to manage highly relational data. On the other side, a great number of applications feature at least some form of user management system. With Neo4J, those users can be store as nodes and connected to other items via relationships. A typical example would be a blog, where both articles and users are individual nodes while authorships are represented by a relationship.
Hazard prediction training web app
One of the companies I worked for put a lot of importance on safety. As a way to improve the employees' awareness of danger, there would be regular meetings during which participants would need to identify dangerous points in a picture. The results were written down and archived on paper, which I believed could be improved. So, I created this web application.
Group and User Pickers
With the user management and group management microservices, users and their groups can be easily queried through HTTP requests. However, the GUI that the user interacts with must also be properly designed so as to provide an optimal UX. To facilitate the query of users via the GUI, I designed a group and user picker component for Vue.js that can be easily installed using NPM.
Smart outlet setup
When used for the first time, the device will have no knowledge of what WiFi to connect to. Consequently, the smart outlet will generate its own, prefixed with the name <em>socket.</em>
Node.js DevOps example
In this article, we’ll build a simple Node.js application that uses Express to respond to HTTP requests. In order to deploy this application to production, we’ll also configure a GitLab CI/CD pipeline so as to dockerize it and deploy its container to a Kubernetes cluster.
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.
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.
RFID wristband
RFID tags are great but often easy to lose. To solve this problem, I designed this case for an RFID tag, which can be worn on one's wrist using a standard watch strap. The case was designed using Fusion360 and then 3D printed.
MongoDB K8s manifest
Here's a simple manifest to deploy MongoDB with data persistence in microk8s:
MQTT control dashboard
With the cloud native multi-user MQTT platform deployed, I started designing IoT devices that I could distribute to end users. However, without a GUI, interacting with those devices would be difficult. Of course, one could install applications like MQTT dash or similar but this would require tedious configuration such as MQTT broker and topics. I wanted to give users a simpler UX so I made this simple control interface that automatically displays a users devices and allows those to be controlled.
