回答:只有你努力 坚持 坚持 就们没有问题。我本人33岁转Java开发从hello world开始 。10年过去已经是加拿大一家公司CTO 但天天仍然写代码。为了第一份开发工作 把整本英文版java core,设计模式,算法 oracle oca 全部背下来 手机里也装了 没事就背诵 理解 。不理解的立马上机写代码。天天白板手写算法。没有工作就到处求人免费帮人做系统。激情燃烧的岁月。所谓岁数精力不够我个...
回答:说一句泼凉水打击的话,自由职业者做编程一点前途没有,趁早打消这样的念头。主要原因是你搞不到赚钱的项目。软件开发不同于送外卖,会骑摩托、能认识门牌号就可以;软件开发者做的软件首先要得到认可,有人愿意用,愿意掏钱。回到正题。不同方向,使用工只不一样。互联网、AI、手机应用开发,先选方向,再决定用VS、JAVA还是Python等工具。
