Of course it is. I moved from the Netherlands to Sweden at 37, not that far from your age. Find a country which fits your needs and wants and start exploring the possibilities. Make sure you're able to learn the language of whatever country you plan to move to or you'll have a hard time integrating/assimilating (depending on the country and your preferences), make sure not to end up in an enclave of compatriots and don't undersell yourself. There is plenty of work for developers in most 'western' countries so in that respect you should be OK.
