I admit that the answer to this question is 10 months old and so you may already have the answer to your question already. Having said that, I would like to add my two cents worth.

One good place to find Java Developers is through freelance platforms like Upwork, Freelancer or even Fiverr. On these sites you will find many Java Developers who are willing to help you with your research projects.

Hope this answers your question and if you need any help with overcoming difficulties in life, then feel free to book a consultation.
