The star rating is a representation of the overall rating, calculated as the mean of the client satisfaction rating, the average client interview rating, and internal interview scores.
The client satisfaction rating is the weighted average of client ratings, with weights based on reviewed work hours. When no client rating exists, the approval fraction (approved vs. reviewed work hours) determines it.
If the client satisfaction rating exceeds the overall rating, it becomes the star rating. In the absence of client ratings, if the average client interview rating is higher than the overall rating, it becomes the star rating. If no data is available, the star rating defaults to the internal interview score.

Project: Automatic Fish Feeder with Smartphone Interface
- It's a project to develop a high-capacity automatic fish feeder to be put in place in a local fish farm. It uses web app as its interface, and a servo to actuate.
- The 3D modeling or design process is done using Fusion 360 CAD (Autodesk). Key features: 3D-printed and able to use any plastic bottle as its reservoir.
- The main system is a NodeMCU, microcontroller similar to Arduino with wireless functionality. The software is developed using Arduino IDE.
- The interface is a web app, hosted by the NodeMCU as an access point. The web app is developed using Bootstrap, HTML, CSS, and Javascript.
- Several technical considerations: Cost and ease of assembly, the web app needs to be small, both the servo and the controller needs to be powered by a common phone adaptor.

Thea Client's Company/Project
Technology Industry
- It's the next phase of a prior project, AIBuddy, and I'm still deeply involved with the tech/skills I've used at that time (REST, Django, JavaScript, Electron, & Tensorflow Js).
- I work in a team to follow a design specification and implement it using Bootstrap in Electron. Bootstrap allows me to design and follow the specification quickly, focusing on things that matter.
- To improve the amount of control I have over the implementation, I work directly with HTML, JavaScript, and CSS alongside the available framework.
- The project will also expand the previous version's database and API (Django & REST) to handle new data and to implement user management.
- Mac Application Development process is necessary to deploy the app for macOS in the Mac App Store. Specifically, I deal with certification, signing, provisioning, & entitlements of the app.
Doing great detailed work.

- REST (DRF) allow me to design versatile APIs for external communication with the website, from streaming webcam image, various type of statistics, log user historical data, and multi-user management.
- Using Electron, I can turn my web dev skills such as JavaScript, JQuery, and AJAX to develop a native app across different platforms. It increases my focus on the functionality rather than the OS.
- Tensorflow library on Python gives me a lot of freedom in implementing my ideas for Machine Learning system. Here we're implementing Emotion and Posture recognition.
Updated the readme documentation, pushed code frequently, evaluating his work still, but I like his responsiveness and committing style so far. Update -- he completed our MVP -- excellent work.
