Parsing million records

Budget: 5000 UAH Deadline: 3 days

Hello.

I develop bots and parsers in NodeJS. I am ready to take on the project. Write to me, we will discuss.

I will implement without problems, the price on the condition that there will be no blocks, please contact me, I will implement in a stack convenient for you.

Good day. It's not a problem to do this, but I would still like to first take a look at the table and the JSON. You can review my work experience in the feedback history.

Hello! 👋

I have experience in developing systems for processing large volumes of data (millions of records), including CSV import, working with JSON, optimizing MySQL, and automatically updating data on a schedule. I will be able to implement a stable process for processing your file with the assortment and photos.

Here’s how I will implement it:

importing the original CSV (200k records) into a MySQL table while preserving the structure + update date field;

processing JSON from the link and extracting URLs of all photos;

writing photos into a separate table (up to 4 million records) linked to the product;

optimizing the database structure (indexes, batch inserts, chunk processing);

automatically updating data 5 times a day via cron;

a logging system, import correctness checks, and error control;

optimizing the speed of processing large volumes of data.

I have worked on tasks that require processing millions of records and large data arrays, so I pay special attention to the performance and stability of the process.

I am ready to discuss the details of the CSV and JSON structure, after which I will be able to estimate the timeline and budget. Expand

Hello. I have experience with parsing csv and json. I am ready to create a structured database, but first I would like to see the structure of the csv. I can also provide a script if information will be added to the csv with this structure.

Good day, Dmytro
I have advanced knowledge of MySQL and working with similar parsing.
Feel free to contact me, I will help create a solution that works quickly and reliably.
I am waiting for feedback.

Ready to take it on.
But we need to clarify the details of the order, write!
I will implement it with a script in Python.

Hello, Dmytro.
I have the relevant experience to implement this project.

Hello! 🚀

I have experience working with large volumes of data: importing CSV files with hundreds of thousands of records, processing JSON via links, loading millions of rows into MySQL, building stable ETL/parsing pipelines with scheduled updates, logging, retry mechanisms, and data integrity checks. For your task, I can implement a fast loading system for the assortment, extracting photos into a separate table, updating 5 times a day.

The stack I will be using:

Backend: Python, MySQL, asyncio / aiohttp, multiprocessing
Integrations: CSV import pipeline, JSON parsing, cron / scheduler, logging, retry / monitoring
Infrastructure: Docker, VPS / server, Redis (if needed), CI/CD

I am ready to discuss the project details in person and am ready to start working.

Best regards, Andriy! Expand

Good day, Dmytro!

We have experience working with large datasets — parsing Google Maps with over 200K entries, processing JSON responses, loading into PostgreSQL with deduplication and incremental updates.

Regarding your task:
1. Import CSV (200K rows, 10+ columns) into MySQL with indexes for fast searching + an update date column
2. Parse JSON from links → a separate photo table (2-4 million entries) with a foreign key to the main table
3. Automatic updates 5 times a day on schedule (cron) with logging and integrity checks

For fast processing of millions of entries, we use batch-insert (LOAD DATA / bulk insert), parallel processing of JSON, and process monitoring.

We are ready to show an example of our approach after reviewing the CSV and JSON. We propose working through Safe. Expand

Good day!

I have significant experience working on projects that require the rapid processing of millions of records, including efficient data parsing from APIs and working with MySQL. I am ready to implement your task of updating the assortment and photos.

Write to me in private messages, and we will clarify the details.

Good day
I am interested in your project.
I would like to discuss everything in more detail.

Hello! I have been engaged in data parsing for over 3 years. I implemented a similar project, but instead of images, we worked with archives.

I will be able to implement everything quickly and efficiently! As soon as we discuss the details - I will start working.
