I think your order is very attractive, and I want to offer my services as an experienced programmer.
I would be happy to discuss the details of your application and get started on the project.

Hello!
I am ready to develop a web application for duplicate name checking with fast search and the ability to update the database via interface or API.
It will include: a simple interface, real-time checking, data upload, basic administrator authorization, and search optimization.
Budget: 250 USD Deadline: 3 days
Good afternoon
I have reviewed the technical specifications, everything is clear
I will use Next Js for better authorization, Express for a simple but effective backend, and PostgreSQL for convenient data storage and fast search
Write to me, let's discuss all the details
Budget: 200 USD Deadline: 14 days
Hello.
The project is interesting, ready to start today. For optimal implementation:
— Frontend: React + TypeScript, UI on shadcn/ui (fast, modern, easily extendable)
— Backend: NestJS + WebSocket for real-time communication
— Database: PostgreSQL with indexes on necessary fields (better suited for frequent updates and multi-column search than MongoDB)
Budget: 480 USD Deadline: 8 days
Hello Dmitro,
I have carefully studied your technical specification. The task of creating a fast web program for real-time duplicate checking is exactly the type of project where the right architecture is everything.
To ensure instant checks without page reloads and high performance, I propose using the following modern stack:
Frontend: Next.js (React). This will allow us to create a very fast and interactive user interface.
Backend: Python with the FastAPI framework. FastAPI is one of the fastest web frameworks available, which is ideal for handling real-time requests from the frontend.
Database: PostgreSQL. To ensure lightning-fast searches, I will create an optimized, case-insensitive index on the column containing the names.
This stack will not only meet all your core requirements but will also easily handle the additional features like CSV upload, search history, and a secure admin panel for managing the database.
As a PCAP™ certified Python developer with extensive experience in creating full-stack applications, I can guarantee clean code and a reliable, scalable solution.
My price for creating the entire turnkey application is $480, and I am ready to complete the project in 7-9 days.
Sincerely,
Budget: 150 USD Deadline: 7 days

Можете уточнить интерпретацию слова "приложение" в контексте данного проекта. На каком языке оно должно быть? Это что то отдельное которое подключается к определенному типу баз при вводе ключей доступа? Или же это,что то на хостинге, условно в папке проекта которое будет коннектится к вашей БД,на условном php/python и должно открываться по какому то порту или урлу для работы с вашей БД?
