Glad to hear you enjoyed it! Unfortunately, your position sounds all too familiar. The biggest factor in non-trivial applications is reliability over time, and you are much more likely to achieve it with an old fashioned stack you know inside out. Having said that, I think companies should encourage tinkering and being innovative as well. Just don’t take it to production until you know it like the back of your hand :)
Good luck with your project, I hope you can refactor your application to be well-maintainable without too much rework! And of course, thanks for your response, I appreciate it! :)
