As in have a degree or not? If not, it will make it a lot more difficult as most countries use a point system, and the piece of paper helps. (EDIT: missed that point reading, you do have ignore.)
Most countries are fine for anyone <35yo before they start deducting minor points, by minor I mean like 2/75 based on the Austrian system for every 5 years.
If you have a degree, life will be a lot easier as you get points for that, if hons already done, look at masters maybe, basically you want to be able to stand out so a company can argue to give you a working visa, or enough points to qualify for immigration criteria.
Easiest is ancestry if you have/can, personally have that and just packed bags, left, and now living and working here.
Then language is also important, if non-English (and I think even e.g. Aus/NZ do English cert requirements, can't remember, was on the forum in other threads), do courses in that and usually that's added as points, e.g. German has the Sprachdiplom. You should always endeavor to learn the language of where you want to go.
All you can really do is keep applying to places and hope to get picked, as a software dev what some did was freelance for companies in the country they wanted to work in, and once relationship was good enough/found the right company, ask for a sponsorship (know two friends who did that), others applied to large international companies and did transfer, but that's usually a waiting list and you're going to be working for a few years to get there, and immigration interest over the last few years went up a lot, lots trying to leave, so it's getting more difficult there. These are all like 3-10 year routes though.
So end effect: pick a couple of countries, check their entry requirements and what it is that is pro and con for that country, do remember to rate the culture and the stability quite high as well, e.g. eastern Europe is generally poorer than South Africa, so salary will not be that great, pro is that everyone is poor and theft is still generally low and pricing will be fine, with another con of language is quite difficult to learn for a lot of those countries. Then think 5-10 years in the future, why are young people leaving those regions, etc., research the culture and see if it suits you. Then work your way to it using point system, and then also remember companies can help apply work visa for you based on need, so being specialist for a company helps out.
In terms of funds, save up if you can, you will need a large deposit for rent in a lot of places when you arrive, and in case need to job hunt, you don't have to jump at the first job, it's a job you'll be stuck at for a few years.
