Default Two Actuarial JavaScript Interactive Apps

I've been using my evenings and weekend stuck inside to brush up on some coding projects and wanted to share two of the Actuarial related webapps I've created and see if there is any feedback you guys would like to share or suggestions for other apps that might help students out.

Let me know if you notice any math or logic related errors, I'm always open to constructive criticism! Note they both are optimized for use on a desktop (turns out mobile development is HARD!)

Exposure Rating Using MBBEFD Exposure Curves: A simplified look at exposure rating a single policy using the Bernegger paper on Exam 8, in d3.js/JavaScript

On Level Rate Calculator: A visualization of the parallelogram method for on levelling premiums, as described in Werner & Modlin on Exam 5, written in Django/Python and d3.js/JavaScript

P.S. I make no money off this site (in fact I pay to host it!) so I hope this is ok to post!

I have no idea what those do, but that's impressive!

Then I've failed in my attempt to make this accessible and easy to understand! Something to consider for the next one.

Thanks for checking it out.

No, that's not true at all. I was mainly just playing around with the software. I just meant that I'm not well versed in the actuarial concepts just yet. I will take a deeper look this weekend and try and give you more meaningful feedback.

The layout looks awesome, and the software seems to work well.

If you haven't sat for CAS Exam 5, then I'd suggest starting with the on-level calculator.

If you're on the SOA side of things, I'd also suggest starting with the on-level calculator.

Very cool stuff, this is excellent material to show in one's portfolio!

Personal question, is the development simply a hobby, or are you wishing to explore more in the world of software?

I appreciate the comments. I've been coding for years and try to bring as much of it as I can into my work to make things more efficient or accurate. Most of what I do day-to-day would be more classified as "scripting" (i.e. manipulating a raw dataset), whereas these projects are are more akin to software development (using both those terms loosely) that I do to maintain and develop my coding skills equally as a personal and professional interest.

Great tools; I like this!

On the property curve tool, I had to play with it to understand if "GULR" (ground up loss ratio) meant dollar one or above the deductible, but not the RI layer. Sensibly it meant above the deductible, but then from a semantics perspective is it really 'ground up'?

edit: this probably makes sense for a portfolio but I got thrown off since in this tool we're looking at a single risk...
