Delphi 10 SQLite small development example project

I require Delphi developer who can write a small example project to decode Base64 image data and insert to SQLite DB. I can supply an external file(s) with example Base64 data, I require a small example project that loads the file ... loads it into an onscreen container (memo, etc so it can be seen) then insert it into a simple SQLite database. It is educational use as I do not have time to investigate the appropriate method. It doesn't have to be pretty just clean and simple to follow instructions. Ideally, it should be done without the use of 3rd party components but if necessary please inform me what they are. I expect to be able to open it in Delphi 10.2 and run an example. Appreciate you looking at this job. There will probably be much more to come.
