Hi! Can't you just make a query when the user enters something? I think I can handle this. I just need info whether this is a website or a desktop application. I am new here but I have 8 years of experience as a software engineer, with the last 5 of them - as an android developer. I was also the team lead for an app with 50-100mln installs in the last year. Аs I am just starting here, I can offer expert-level services for a below the average payment - I am still looking for reviews and stats for my profile.
