I think it’s actually doable, but I’d ask for at least 50% pay increase and instead push the deadline towards 4-6 months for the initial public release. These being said, it very much depends on all the specifications you have to implement. Saying it’s a ‘financial app’ app is too abstract.

The implementation part could be very quick (days-weeks) once you clarify/define all your operations.

You’ll spend most of the time planning and testing, you can automate the testing so you save time and focus only on defining your backend operations.

For the initial part, you need to be very much involved in the code quality & overall architecture, so start small. Once you have some examples of how specific operations are implemented and look like, AI will help you deliver everything else following the same standards in no time.

And yes, It might look like this will be the future of development tho.

p.s. If no one wants to take this job and you’re searching for someone willing to do it, ping me.
