Create proof read and dictionary API and UI

I am looking for a skilled developer to create a proofread and dictionary API with a user-friendly UI.
This should have a learning model, as per language inputs and user using the language.
This learning model is majorly for INDIC Languages. Having knowledge of unicode UTF8/UTF16 encoding is necessary.
We have data over a million records in mySQL. Programming should be efficient to add up another million.
Output needs to be efficient and quick.

– The API should be built using Python or PHP to be able to host in shared hosting or dedicated hosting. Present DB is MySQL but I am open for NoSQL as well.

Please note:

No calls and personal numbers will be entertained. No Paypal payments.
I work only with direct developers not teams. so no marketing people please.
Preference would be given to who have done similar work previously. please highlight same in your bid.
If you have not done similar projects previously you need to show a basic demo before creating milestone so that I get confidence you can do this job.

Delivery should be within 7 days.
If interested please drop a message in the enquiry box I will ping you or you can send me chat requests.
